There are 128 three digit numbers divisible by 7
We know that the divisibility rule of 7 is:
If the difference between twice the unit digit of the given number and the remaining part of the given number is multiple of 7 or the difference is 0, then the number is divisible by 7.
the range of three digit numbers is 100 to 999
The first three-digit number divisible by 7 is 105 and the last three-digit number divisible by 7 is 994.
The numbers divisible by 7 must be: 105, 112, . . ., 994
We can observe that the above series represents the arithmetic progression with common difference d = 7, the first term a = 105 and the last term a_n = 994
We know that the formula for the n-th term of AP is:
a_n = a1 + (n - 1)d
994 = 105 + (n - 1)7
7n - 7 = 889
7n = 889 + 7
7n = 896
n = 128
Thus, there are 128 three digit numbers.

A garden table and a bench cost $621 combined. The garden table costs $79 less than the bench. What is the cost of the bench?
Answer:
$389.5
Step-by-step explanation:
621/2 = 310.5 assuming they're equal therefore, it is stated that the table cost cost 79 less than the bench so we substract.
310.5 - 79 = 231.5
This is the cost of garden table, lets find the bench now.
621(both table and bench)-231.5(garden table)= 389.5 is the cost of the bench.
What are the 3 defining characteristics of parallel lines?.
The characteristics of parallel lines:
1) Parallel lines lie in the same plane
2) The parallel lines never intersect each other.
3) The slopes of parallel lines are equal.
We know that two lines are parallel to each other if they lie in the same plane and never intersect each other.
Parallel lines are always equidistant from each other.
Also, the parallel lines are coplanar.
Mathematically, the parallel lines are represented by the symbol, ‘||‘.
If two lines l₁ and l₂ are parallel to each other then they are represented as l₁ || l₂.
Also, the slopes of parallel lines are equal.
Let m₁ be the slope of line l₁ and m₂ be the slope of line l₂.
If line l₁ and l₂ are parallel to each other then m₁ = m₂

The amount of revenue for a business can be modeled by the function
L(t) = 7300(1.012) 4t. Write an equivalent function of the form L(t) = abt.
Round your final values to 4 decimal places.
Answer:
a=7300, b=1.0108.
L(t) = 7300(1.0108)^t
Step-by-step explanation:
First, we can see that L(t) = 7300(1.012)^(4t) can be rewritten as L(t) = 7300e^(4tln(1.012))
Using the properties of logarithms, we can simplify this to L(t) = 7300e^(4t(ln(1.012))
Now, we can see that the function L(t) is in the form L(t) = ab^t, where a = 7300 and b = e^(ln(1.012))
Therefore, we can write the equivalent function as L(t) = 7300e^(0.048t)
The final values rounded to 4 decimal places are a=7300, b=1.0108.

Without knowing its side lengths, can you determine the ratio of the perimeter of a square to the length of one of its sides? Explain.
A square's side to perimeter ratio is one to four.
How do you calculate a perimeter's ratio?The quantity of two-dimensional space a shape occupies is referred to as its area. Simply dividing the perimeter by the area yields the ratio of a shape's perimeter to area. It is simple to calculate this. The perimeter ratio and scale factor are the same. In reality, the scaling factor for every ratio between any two similar shapes is the same (diagonals, medians, midsegments, altitudes, etc.).The Perimeter is equal to a constant multiplied by the Side length, or the Perimeter is equal to four when divided by the Side length. There is so no doubt that the link between Side length and Perimeter is proportionate.To learn more about ratio, refer to:

A bakery ell pie and cake. In November, they old 400 pie and 250 cake totaling $8,550. In December, they old 300 pie and 500 cake totaling $11,100. What i the price of the pie?
The price of the Pie will be $12 and the price of the cake will be $15.
We will solve this problem with the help of equations.
Let the price of Pie be $X and the price of Cake be $Y.
According to a given question in November, they sold 400 Pie and 250 Cake and the total amount is $8550.
So our first equation will be,
400X + 250Y = 8550.
And in December they sold 300 pies and 500 cakes respectively totaling $11100.
So our second equation will be:
300X + 500Y = 11100.
Taking the value of X from our first equation we get:
X = (8550-250Y)/400
Putting it in our second equation we get:
300(8550-250Y)/400 + 500Y = 11100
On solving this:
3/4(8550-250Y)+500Y = 11100
25650/4 - 750/4 Y + 500Y = 11100
1250/4 Y = 18750/4
Y = 15
So the price of the Cake is $15.
Similarly, we can find the price of Pie as (8550-250*15)/400 = 12
So the price of the pie is $12.
Therefore the price of the pie is $12 and the cake price is $15.

Part B: If the parent function f(x) = |x| is transformed to h(x) = |x| + 2, what transformation occurs from f(x) to h(x)? How are the vertex and range of h(x) affected?
Part A:
The graph of the function g(x) = |x - 7| is a V-shaped graph that opens upwards and has a vertex at x = 7. The vertex is the midpoint of the graph and occurs at the value of x where the absolute value changes from positive to negative. The domain of the function is all real numbers and the range is all non-negative numbers.
Part B:
The transformation from f(x) to h(x) occurs by shifting the graph of the parent function up by 2 units along the y-axis. In other words, every y-coordinate in the graph of f(x) is increased by 2 in the graph of h(x). The vertex of the parent function is (0,0) and is shifted to (0,2) in the transformed function. The range of h(x) is all non-negative numbers greater than or equal to 2.

Answer:
y = 10 and x = 5
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{5\sqrt{3} }{y}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
y × [tex]\sqrt{3}[/tex] = 10[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 10
-----------------------------------
using Pythagoras' identity in the right triangle
x² + (5[tex]\sqrt{3}[/tex] )² = y² = 10²
x² + 75 = 100 ( subtract 75 from both sides )
x² = 25 ( take square root of both sides )
x = [tex]\sqrt{25}[/tex] = 5

The ideal utilization would be $150but he can choose to borrow $1050
What is a credit card in simple words?A credit card is a type of credit facility, provided by banks that allow customers to borrow funds within a pre-approved credit limit. It enables customers to make purchase transactions on goods and services.
Given here: Bob's credit limit is $3500 and he has a balance of $2200
Therefore available credit is equal to $3500-$2200=$1300
Thus if he spends more than $1300 then he goes over his limit.
But ideal utilization ratio is 30% and therefore 30%×3500=$1050
Thus ideal credit usage would be = 3500-1050

How should you graph the equation y =- 3 4x 2?.
The final graph is given below in the image.
The equation is [tex]y = -\frac{3}{4}x - 2[/tex]
The graph of a linear equation in two variables is a line (that's why they call it linear).
If you know an equation is linear, you can graph it by finding any two solutions
(x1,y1) and (x2,y2)
plotting these two points, and drawing the line connecting them.
You can find two solutions, corresponding to the x-intercepts and y-intercepts of the graph, by setting first x=0 and then y=0.
To graph the line [tex]y = -\frac{3}{4}x - 2[/tex] we are going to take advantage of the fact that its y-intercept is -2 when x = 0, so our first point is (0,-2). To find our second point, we are going to find the x-intercept; to do it, we are going to set y = 0 and solve for x:
[tex]y = -\frac{3}{4}x - 2\\0 = -\frac{3}{4}x - 2\\2 = -\frac{3}{4}x \\x = -\frac{8}{3}[/tex]
Now, we have our second point (0, -8/3), we just need to join the 2 points with a straight line.

DRIVING While on a bike ride, Tyra’s distance from home can be modeled by f(x) = −15∣∣x−40∣∣+8
, where x is the time since Tyra left home in minutes and f(x) her distance from home in miles. Graph the function on a separate piece of paper. Find and interpret the key features of the graph in the context of the situation.
The graph of the function f(x) = −15|x−40|+8 will be a piecewise linear function.
Graph explain: What is it?
A graph is defined as a mathematical structure that connects a collection of points to express a specific function. A pairwise relationship between the objects is established using it. The edges that connect the graph's vertices (also known as nodes) are its vertices (lines).
It will be a V-shape, with the vertex at x = 40 and y = 8.
On the left side of the vertex, the function will be decreasing, representing Tyra moving away from home.
On the right side of the vertex, the function will be increasing, representing Tyra moving towards home.
The vertex at x = 40 and y = 8 represents the point in time where Tyra reaches her furthest distance from home (8 miles) and then begins to head back towards home.
Key features of the graph in the context of the situation:
The vertex at x = 40 and y = 8 represents the point in time where Tyra reaches her furthest distance from home (8 miles) and then begins to head back towards home.
The left side of the vertex represents the time period when Tyra is moving away from home, and the right side represents the time period when Tyra is moving towards home.
The slope of the graph on the left side of the vertex is negative, indicating that Tyra is moving away from home at a decreasing rate, while the slope of the graph on the right side of the vertex is positive, indicating that Tyra is moving towards home at an increasing rate.
The y-intercept is at 8, which means Tyra starts 8 miles away from home.
The graph is symmetric about the y-axis because for every time x on the left side of the vertex, there is a corresponding time on the right side of the vertex.
The graph is not a function because for every x value, there are two y values, one for when Tyra is moving away from home and one for when Tyra is moving towards home.

The lengths of all three sides of the triangle are;
43.6 inches
52.3 inches
61.1 inches
What are the lengths of the triangle?The arcs are seen to be two times the angles and as such, the arc made by the 50° angle is 100° and then we see that the one made by the 60 degree angle given as 120°.
Formula for the circumference of a circle is;
C = 2πr
C = 50π inches
C = 157 inches
The arc made by the 50° angle is;
Arc length = 157*100/360
= 43.6 inches
The arc length made by the 60° angle = 157(120/360)
= 52.3 inches
The arc length made by the remaining 70° angle is;
Arc length = 157(140/360)
