Answer:
The answer is 0.165 inches.
Step-by-step explanation:
The volume of a rectangular pool can be calculated as the product of its length, width, and depth. To find out how much the water level increased, we'll calculate the volume of one quart of water and compare it to the volume of the pool.
One quart is equivalent to 0.946 liters, and 1 liter of water has a volume of 1000 cubic centimeters. Therefore, one quart of water has a volume of 0.946 liters x 1000 cubic centimeters/liter = 946 cubic centimeters.
Since 1 cubic foot is equivalent to approximately 28,317 cubic centimeters, the volume of one quart of water in cubic feet is:
946 cubic centimeters / 28,317 cubic centimeters/cubic foot = 0.033 cubic feet.
The volume of the pool can be calculated as:
12 ft x 20 ft x depth (in feet) = 240 cubic feet
So, if the pool is 12 ft x 20 ft, the water level increased by:
0.033 cubic feet / 240 cubic feet = 0.0001375 feet = 0.165 inches.
Therefore, the water level in the pool increased by approximately 0.165 inches.

The pre-image, quadrilateral ABCD was dilated to produce the image, quadrilateral A'B'C'D'. The length of the side between the vertices A and B is 5 inches. What is the length of the side between the vertices A' and B', when vertices B'C' is 9 inches and vertices BC is 12 inches?
The length of the side between the vertices A' and B' is 3.75 inches
How to find the length of the side between the vertices A' and B'?In order to find the length of the side between the vertices A' and B', we need to use the fact that the ratio of corresponding side lengths between the pre-image and the image is the same as the ratio of the scale factor used in the dilation.
The ratio of the side length between the vertices B'C' and BC is 9/12. If we call this ratio k, then the ratio of the side length between the vertices A'B' and AB is also k.
So we can use the side length between AB = 5 inches and k = 9/12 to find the side length between A'B'
A'B' /AB = k
A'B' = k × AB
A'B' = (9/12) × 5

The solution to the equation m+[tex]n^{2}[/tex] = g5M is g = m[tex]n^{2}[/tex]/5M, which can be solved by dividing both sides of the equation by 5M and rearranging the equation to isolate the g on the right side.
What is an equation?A mathematical declaration that two expressions are equal is known as an equation. The equal symbol (=) is used to denote the separation of two phrases.
In the given question, we must isolate the g on one side of the equation in order to solve this equation for g. We may start by multiplying both sides of the equation by 5M to accomplish this. This will result in the left side of the equation having m/5M + ([tex]n^{2}[/tex]/5M). It will only provide us with g on the right side.
The terms on the left side of the equation can then be combined by multiplying them together. This will result in the equation shown below: (m/5M)([tex]n^{2}[/tex]/5M) = g.
The fractions can then be eliminated and the denominators removed by multiplying both sides of the equation by 5M. This will result in the formation of 5Mg on the right side and mn2/5M on the left.
We can then rearrange the equation to isolate the g on the right side, giving us: m[tex]n^{2}[/tex] = 5Mg. Finally, we can divide both sides of the equation by 5M to get g by itself on the right side, giving us the final equation: g = m[tex]n^{2}[/tex]/5M.

The average of a set of numbers is defined as:
[tex]\dfrac{\textrm{sum of values}}{\textrm{number of values}}[/tex]
In this problem, we are shown a table where each row has a coupon value in the left column and the number of that coupon value in the right column (e.g., if we look at the top row, we can see there are 70 coupons each valued at $10).
So, the sum of values in this problem (i.e., the total number of dollars given out by the store in the form of coupons) is defined as the sum of the product of each row.
[tex]\textrm{sum of values} = (\$10 \times 70) + (\$20 \times 40) + (\$40 \times 20) + (\$60 \times 4) + (\$120 \times 2)[/tex]
[tex]\textrm{sum of values} = \$700 + \$800 + \$800 + \$240 + \$240[/tex]
[tex]\textrm{sum of values} = \$2780[/tex]
The number of values in this problem is just the sum of the numbers in the right column (i.e., the number of coupons given out).
[tex]\textrm{number of values} = 70 + 40 + 20 + 4 + 2[/tex]
[tex]\textrm{number of values} = 136[/tex]
Finally, to answer the problem, we can plug the two numbers that we just solved for into the formula for the average of a set.
[tex]\textrm{average savings} = \dfrac{\textrm{value of all tickets}}{\textrm{number of tickets}}[/tex]
[tex]\textrm{average savings} = \dfrac{\$2780}{136}[/tex]
[tex]\textrm{average savings} \approx \$20.44[/tex]
Caitlyn needs to mail a USB drive to a friend. She uses 42 -cent stamps and 5 -cent stamps to pay $1.71 in postage. How many of each stamp did Caitlyn use?
Solving an equation we will see that Caitlyn used 3 of the 42-cent stamps and 9 of the 5-cent ones.
How many of each stamp does she use?Let's define the variables that we will be using:
x = number of 42-cent stapms.y = number of 5-cent stamps.Then the total value of the stamps, in dollars, is:
x*0.42 + y*0.5
And we know that the value must be $1.71, then we can write the equation:
x*0.42 + y*0.05 = 1.71
y = (1.71 - x*0.42)/0.05
To find the values of x and y, we can just evaluate in different whole values of x, until we get a whole value of y.
using x = 1 we get:
y = (1.71 - 0.42)/0.05 = 2.58
This is not a solution.
if x = 3
y = (1.71 - 0.42*3)/0.05 = 9
This is the solution, she used 3 of the 42-cent and 9 of the 5-cent.

Find a vector (u ) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ Give EXACT answer. You do NOT have to simplify your radicals!
u =
A vector (u) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ is u = ⟨-2/√13, 3/√13⟩.
A vector in the opposite direction of a given vector can be found by multiplying that vector by -1. The magnitude of a vector is the length of the vector and it can be found by using the Pythagorean theorem on the coordinates of the vector.
The magnitude of the vector v = ⟨-2,3⟩ is:
|v| = √(-2)^2 + 3^2 = √4 + 9 = √13
To find a vector with magnitude 4 in the opposite direction as v, we can first normalize the vector v by dividing it by its magnitude,
then multiply it by 4:
u = (-1) * (1/|v|) * v
= (-1) * (1/√13) * ⟨-2,3⟩
= ⟨2/√13, -3/√13⟩
So, a vector (u) with magnitude 4 in the opposite direction as v =⟨−2,3⟩ is u = ⟨2/√13, -3/√13⟩

y = [tex]\frac{1}{5} x+c[/tex]
4 = [tex]\frac{1}{5}[/tex][tex](-10)[/tex][tex]+c[/tex] (make c the subject)
c = 4 + 2
c = 6 (this is the y-intercept that is needed when creating the equation of the line)
therefore: [tex]y=\frac{1}{5} x+6[/tex]

Step-by-step explanation:1. Identify the data.We're given the slope and an ordered pair the function passes through.
[tex]\sf Slope (m)=\dfrac{1}{5}[/tex]
[tex]\sf Point: (-10,4)\\ \\Therefore:\\x_{1}=-10\\y_{1} =4[/tex]
2. Use the formula for calculating linear equations based on the slope and a point.Here's that formula: [tex]\sf y-y_{1} =m(x-x_{1} )\\ \\[/tex]
3. Substitute the variables in the formula by the identified values on step 1.[tex]\sf y-(4) =(\dfrac{1}{5} )(x-(-10) )\\ \\[/tex]
4. Calculate.[tex]\sf y-(4) =(\dfrac{1}{5} )(x+10 )\\ \\\\\sf y-(4) =(\dfrac{1}{5} )(x)+(\dfrac{1}{5} )(10)\\ \\ \\\sf y-(4) =\dfrac{1}{5} x+(\dfrac{10}{5} )\\ \\ \\\sf y-4 =\dfrac{1}{5} x+2\\ \\ \\\sf y-4+4 =\dfrac{1}{5} x+2+4\\ \\ \\\sf y =\dfrac{1}{5} x+6[/tex]
5. Verify the answer.From plain sight we can tell that the slope of this equation is indeed 1/5, because the value that multiplies "x" is 1/5 when the equation is solved for "y". Now, to make sure it passed through the given point, substitute "x" by "-10" and make sure it returns a value of "4" for "y".
[tex]\sf y =\dfrac{1}{5} (-10)+6\\ \\ \\\sf y =\dfrac{-10}{5}+6\\ \\ \\\sf y =-2+6\\ \\ \\y=4[/tex]
The answer is correct!
Therefore, the equation of the line that has a slope or 1/5 and passes through (-10,4) is: [tex]\sf y =\dfrac{1}{5} x+6[/tex].

How do you find a arc length without a radius? Need a answer asap.
the length of the arc will be C/2π*Ф.
What is circle?
The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.
The radius of a circle and its centre angle both affect how long an arc is. We are aware that the arc length and circumference are equivalent at an angle of 360 degrees (2). Due to the continuous relationship between angle and arc length, we can therefore state that:
L/Ф = C/2π
L = C/2π*Ф
Hence the length of the arc will be C/2π*Ф.

A population proportion is 0.30. A random sample of size 150 will be taken and the sample proportion p will be used to estimate
the population proportion. Use the z-table.
Round your answers to four decimal places.
a. What is the probability that the sample proportion will be within ±0.03 of the population proportion?
b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?
In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.
What is probability?
Probability is a measure of the likelihood that an event will occur, it is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
In this case, we are interested in the probability that the sample proportion (p) will be within a certain range of the population proportion (0.30).
a. To find the probability that the sample proportion will be within ±0.03 of the population proportion, we can use the standard normal distribution (z-table). The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.
The formula for the standard normal distribution is:
z = (p - 0.30) / (standard deviation of p)
The standard deviation of p is given by the formula:
(population proportion * (1 - population proportion)) / sample size
In this case, we have:
(0.30 * (1 - 0.30)) / 150 = 0.0006
So, the standard deviation of p is 0.0006
The probability that the sample proportion will be within ±0.03 of the population proportion is the same as the probability that the sample proportion will be between 0.27 and 0.33.
Therefore, we can calculate the z-score for the lower and upper bounds of the range:
z1 = (0.27 - 0.30) / 0.0006 = -5
z2 = (0.33 - 0.30) / 0.0006 = 5
Using the z-table, we can find the probability that a z-score falls between -5 and 5.
The probability that the sample proportion will be within ±0.03 of the population proportion is:
P(z1 <= z <= z2) = P(-5 <= z <= 5) = 1 - 0.0000 = 1.0000
b. To find the probability that the sample proportion will be within ±0.08 of the population proportion, we can use the same formula as before. The probability that the sample proportion will be within ±0.08 of the population proportion is the same as the probability that the sample proportion will be between 0.22 and 0.38.
Therefore, we can calculate the z-score for the lower and upper bounds of the range:
z1 = (0.22 - 0.30) / 0.0006 = -10
z2 = (0.38 - 0.30) / 0.0006 = 10
Using the z-table, we can find the probability that a z-score falls between -10 and 10.
The probability that the sample proportion will be within ±0.08 of the population proportion is:
P(z1 <= z <= z2) = P(-10 <= z <= 10) = 1 - 0.0000 = 1.0000
Hence, In both cases, the sample proportion is very likely to be within a certain range of the population proportion, with a probability of 1.0000 or 100%.

Find the equation of the solution through the point (x,y)=(6,0). Your answer should be of the form x=f(y) or y=f(x), whichever is appropriate.
The implicit solution of the differential equation dy/dx=x/(25*y) is y = (3(25x^2/2 + c))^(1/3) = constant. The equation of the solution through the points (x,y)=(-5,1), (x,y)=(0,-6), and (x,y)=(6,0) are y = (3(25x^2/2 - 313.75))^(1/3), y = (3(25x^2/2 - 1875))^(1/3), and y = (3(25x^2/2 - 2025))^(1/3) respectively.
1. 25y^2dx = xdy → y^2 dy = 25x dx → ∫y^2 dy = ∫25x dx → y^3/3 = 25x^2/2 + c → y = (3(25x^2/2 + c))^(1/3) = constant
2. Substituting x=-5 and y=1 in the implicit solution, we get (3(25(-5)^2/2 + c))^(1/3) = 1 → c = -313.75 → y = (3(25x^2/2 - 313.75))^(1/3)
3. Substituting x=0 and y=-6 in the implicit solution, we get (3(25(0)^2/2 - 313.75))^(1/3) = -6 → c = -1875 → y = (3(25x^2/2 - 1875))^(1/3)
4. Substituting x=6 and y=0 in the implicit solution, we get (3(25(6)^2/2 - 1875))^(1/3) = 0 → c = -2025 → y = (3(25x^2/2 - 2025))^(1/3)
The implicit solution of the differential equation dy/dx=x/(25*y) is y = (3(25x^2/2 + c))^(1/3) = constant. The equation of the solution through the points (x,y)=(-5,1), (x,y)=(0,-6), and (x,y)=(6,0) are y = (3(25x^2/2 - 313.75))^(1/3), y = (3(25x^2/2 - 1875))^(1/3), and y = (3(25x^2/2 - 2025))^(1/3) respectively.

What is the exponential function?
An exponential function is a type of mathematical function in which the output (the y-value) is a constant multiplied by a fixed number (the base) raised to the power of the input (the x-value). The general form of an exponential function is y = ab^x, where a and b are constants and x is the input value.
1 .To estimate f(1/3) using the graph points (0, 12) and (1, 0.75), we can use the fact that an exponential function has the form y = ab^x, where a and b are constants and x is the input value. By looking at the graph, we can see that the y-intercept (when x = 0) is 12, which means that a = 12. We can also see that the function passes through the point (1, 0.75), which means that f(1) = 0.75. Using this information, we can write the equation for the function as:
y = 12b^x
f(1/3) = 12b^(1/3)
Since we don't know the value of b, it's impossible to know the exact value of f(1/3) from the given information. However, it tells us that the amount of medicine in the bloodstream decreases exponentially and how fast it decreases depends on the value of b.
2. To find the equation that defines f, we can use the point (1, 0.75). We know that f(1) = 0.75, so we can substitute this into the equation we found earlier:
0.75 = 12b^1
0.75 = 12b
b = 0.0625
So, the equation that defines f is:
y = 12 * 0.0625^x
or
y = 0.75 * 0.0625^x
This equation tells us that the amount of medicine in the bloodstream decreases exponentially with time, with a rate determined by the value of b = 0.0625.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle.
The area of the region enclosed by the given curves is 32 units2.
The region enclosed by the given curves is bounded by the equation y = x2 and y = 4. The region is a parabolic region and needs to be integrated with respect to y. A typical approximating rectangle for this region is shown in the diagram below.
The area of this region can be expressed as the integral:
A = ∫y=x2→4 y dx
This integral can be evaluated by splitting the integral into two parts: A = ∫y=x2→4 x2 dx + ∫y=x2→4 4dx
After evaluating the integrals, the area of the region is:
A = (1/3)x3 + 4x |y=x2→4
A = (1/3)(42) + 4(4 - 22)
A = 32
Therefore, the area of the region enclosed by the given curves is 32 units2.
