plss help asap, my assignment is due today and I have been trying to solve this for the past 3 days​

Answer: The answer is: 525 millimeters of compound A are needed.

Step-by-step explanation:
You have to put it in equation form to solve for compound A. To do this use variables.

7(x) + 5(x) = 900
12(x) = 900
x = 900/12
x = 75
When we get 75 you have to plug it into compound A to get this:
7(75) = 525

To confirm our answer we plug in 75 to both variables.
7(75) + 5(75) = 900

I hope this was able to help you :D

Answer: The equation that can be used to determine the total amount in Justin's account is:

b = 50 + (12 * w)

This equation represents the total amount in Justin's account, b, after w weeks. The equation starts with the initial amount, $50, which is the amount Justin had in his account before making any deposits. Then, it adds the amount deposited each week, $12, multiplied by the number of weeks, w. This results in the total amount in the account after w weeks.

In this equation the variable "w" represents the number of weeks that have passed and "b" represents the total balance.

Step-by-step explanation:

The functions are 0, -2 and 1 for the mentioned function is 4, - 16 and 2.

Firstly we will represent the function in equation form. Then we will calculate the result by keeping each value of function.

f(x) = x³ - 3x² + 4

Calculating result when function is 0

f(x) = 0³ - 3×0² + 4

f(x) = 0 - 0 + 4

f(x) = 4

Calculating result when function is -2

f(x) = (-2)³ - 3×(-2)² + 4

Finding square and cube

f(x) = -8 - 3×4 + 4

Performing multiplication

f(x) = - 8 - 12 + 4

Performing addition

f(x) = - 20 + 4

Performing subtraction

f(x) = - 16

Calculating result when function is 1

f(x) = 1³ - 3×1² + 4

f(x) = 1 - 3 + 4

Performing addition

f(x) = 5 - 3

Performing subtraction

f(x) = 2

Thus, functions are 4, -16 and 2.

The concession stand charges $2.25 for each nacho.

What is the percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" is also used. A percentage is a dimensionless number; it has no unit of measurement.

To find out how much the concession stands charge for each nacho, we need to calculate the markup percentage.

The markup percentage is calculated by:

(Markup Amount / Cost) * 100 = Markup Percentage

In this case, the markup amount is 80% of the cost of each nacho, which is:

(80/100) * $1.25 = $1

So, the markup amount is $1.

To calculate the final price of each nacho, we need to add the markup amount to the cost:

$1.25 (cost of nacho) + $1 (markup amount) = $2.25

Therefore, the concession stand charges $2.25 for each nacho.

The greatest prime factor of 2516 is 11, so the answer is A. 11

What is the prime factor?

A prime factor is a natural number, other than 1, whose only factors are 1 and itself. The first few prime numbers are actually 2, 3, 5, 7, 11,

We can use the process of counting to find the sum of all the numbers in S.

For one-digit numbers, there are 2 possibilities (0 or 1).

For two-digit numbers, there are 2 x 2 = 4 possibilities (00, 01, 10, 11).

For three-digit numbers, there are 2 x 2 x 2 = 8 possibilities (000, 001, 010, 011, 100, 101, 110, 111).

For four-digit numbers, there are 2 x 2 x 2 x 2 = 16 possibilities (0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111).

So, the sum of all the numbers in S is

2 + 4(1+2+3+4) + 8(1+2+3+4+5+6+7+8) + 16(1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16)

We can simplify this expression as

2 + 4(10) + 8(36) + 16(136)

The sum of all the numbers in S is equal to 2 + 40 + 288 + 2176 = 2516.

Hence, The greatest prime factor of 2516 is 11, so the answer is A. 11

Step-by-step explanation:

reading the question thoroughly, we find out that volume (V) and radius (r) of the cone is given, and we just have to find out the length (h) of the cone

V = πr²h/3

Putting the given values in place,

V = 75.36 cm³

V = 75.36 cm³r = 2 cm

V = 75.36 cm³r = 2 cmπ = 3.14

Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.

h = 3V/(πr²)

h = 3×75.36/(3.14×2²)

h = 226.08/12.56

h = 18 cm

42 divided by 6=7 so in each vase there are 7 flowers

Step-by-step explanation:

Answer:

Width = 3.773 inches

Length = 79.227 inches-

Step-by-step explanation:

g = 7(3w)             Eq. 1

166 = 2(g+w)       Eq. 2

g = length

w = width

From Eq, 1:

g = 21w              Eq. 3

Replacing Eq. 3 in Eq. 2

166 = 2(21w + w)

166 = 2(22w)

166 = 44w

166/44 = w

w = 3.773

From Eq. 3

g = 21(3.773)

g = 79.227

Check:

From Eq. 2:

166 = 2(79.227 + 3.773) = 2 * 83

after mixing 1 can of concentrate and 3 cans of water, we will have 4 cans of juice.

the volume of 1 can is (as for any cylinder or regular 3D object)

pi×r²

r is the radius, which is half of the diameter.

in the picture it is not fully clear what is 2.25 in long : the diameter of the radius ?

I suspect it is the diameter.

so, the radius of our cans is 2.25/2 = 1.125 in

the volume of 1 can is

pi×1.125²×4.25

and the volume of all 4 cans of juice is then

4×pi×1.125²×4.25 = 17×3.14×1.265625 = 67.5590625 in³

so, your answer is 68.

The values of p and q are given as follows:

p = 3.5, q = 6.

Hence the factored expression is given as follows:

The function f(x) is divisible by 2x² - 7x + 6, which has the roots given as follows:

x = 1.5 and x = 2.

(using a quadratic equation calculator with coefficients a = 2, b = -7 and c = 6).

Hence the following relation holds true, considering the linear factors of the function:

2x³ + px² + 8x + q = 2(x - 1.5)(x - 2)(x - a).

In which a is the third root.

Hence:

2x³ + px² - 8x + q = 2(x² - 3.5x + 3)(x - a)

2x³ + px² - 8x + q = 2(x³ - x²(3.5 + a) + x(3.5a + 3) - 3a)

2x³ + px² - 8x + q = 2x³ - x²(7.5 + 2a) + x(7a + 6) - 3a.

Hence the system of equations is given as follows:

From the second equation, the value of a is given as follows:

7a = -14

a = -2

The coefficient of the second derivative (t2) is constant, so the equation is linear.

1. (1+y2)(d2y/dt2)+t(dy/dt)+y=et2  ->  2nd. order non-linear differential equation

2. t2(d2y/dt2)+t(dy/dt)+2y=sin t  ->  2nd. order linear differential equation

3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t3  ->  3rd. order non-linear differential equation

4. y''-y+y2=0  ->  2nd. order non-linear differential equation

The order of a differential equation is the highest derivative involved in the equation. For example, in the equation 1 + y2(d2y/dt2) + t(dy/dt) + y = et2, the highest derivative is the second derivative (d2y/dt2), so this equation is of 2nd order. Linearity is determined by whether the coefficients of each derivative are constants, or whether they depend on the function y and its derivatives. In this equation, the coefficient of the second derivative (1+y2) is not constant, so the equation is non-linear. Similarly, in equation t2(d2y/dt2)+t(dy/dt)+2y=sin t, the coefficient of the second derivative (t2) is constant, so the equation is linear.
