a rectangular suitcase measure 24 inches long and the diagonal is 30 inches long. the zipper covers the entire perimeter of the suitcase. how many inches of the zipper was needed to cover the perimeter of the suitcase?
Answers
Given parameters:
Length of the suitcase = 24 inches
Length of the diagonal = 30 inches
Unknown:
Length of zipper required to cover the perimeter = ?
The length of this zipper is the same as the perimeter of the rectangular suitcase.
Perimeter of a rectangle = 2(L + B)
where L is the length and B is the breadth
Now, let us find the find the unknown breadth;
Using Pythagoras theorem;
30² = 24² + Breadth²
Breadth² = 30² - 24² = 324
Breadth = √324 = 18 inches
Perimeter of the suitcase = 2(24 + 18) = 84 inches.
The length of zipper that will cover this suitcase is 84inches.

Answer:
at 65 texts , co 2 costs more
19.99 + .25x > 35.99
x= number of texts
Step-by-step explanation:
19.99 + .25x = 35.99
x= number of texts
.25x= 35.99-19.99

You have to but the numbers in order than you cross each of the ends until you get the middle number/median
Answer: 9
Step-by-step explanation:
The median in math is basicly the middle of the list. First, put the list in order from least to greatest. Then, find the middle. If there is no middle, add the two numbers in the middle. Add them together, and divide the sum by two. The quotient is the median.
In this case, there is a middle. The middle is nine. Nine is the median.

Answer:
1. b 2. b
Step-by-step explanation:
1. In the graph it shows a negative slope so we can immediately eliminate a and c since they have a positive slope as shown in the equation. Then the initial value is the y coordinate when x is 0. In the graph you can see that when x is 0 y is 18 so the equation would be h= -3+18
2. In the problem it says that Jennifer is paid $2,200 as a base salary. This means that this is her initial value. Then you can see that she gets paid 300 extra for every car she sales. This is the rate of change. The equation will be y=300x+2,200
fyi 300 goes first because it is the rate of change and those always go first.

The equation y =0.7x represents the distance Henry hikes in miles over time in hours. The graph
represents the rate that Cark hikes. Determine which hiker is faster. Complete the explanation
Henry’s unit rate is ___ miles per hour. Clark’s unit rate is 1.5 miles per hour . So, ____ is faster.
Answers
Answer:
Henry’s unit rate is 0.7 miles per hour. Clark’s unit rate is 1.5 miles per hour . So, Ckark is faster.
Step-by-step explanation:
Distance covered by Henry is represented by y = 0.7x, where x = time (hrs), and y = distance (miles).
Distance covered in 1 hour by Henry would be:
y = 0.7(1) = 0.7 miles per hour
Distance covered by Clark in 1 hour = 1.5 miles per hour
Ckark covers more miles per hour than Henry covers in one hour, therefore, Ckark is faster.

Write the equation of the line with the given point and slope.
(-5, -3); slope = -3/5
Answers
A line in point slope form is y = mx + b
m = the slope
b = y-intercept
So far our line looks like: y = -3/5x + b
Let's plug -5 into x and -3 into y to solve for b
-3 = -3/5(-5) + b
Let's multiply -5 by -3/5
-3 = 3 + b
Subtract 3 from both sides.
-6 = b
Our line is: y = -3/5x - 6
