So because the shape is broken down into right triangles we’ll just use the formula
A = ab/2
and because all of our “a” and “b” are the same
a = 4
b = 3
once we’ve found one triangle
A (one triangle) = 4•3/2
A (one triangle) = 6
we can multiple our answer by 4 to find the total of our whole shape
A = 6•4
A = 24
your answer is 24 in
The
<u>correct answer</u> is:
Matthew's rate is higher by $50 per month.
Explanation:
We know that Christopher's rate is $550 per month.
To find Matthew's rate, we will treat the data we have as ordered pairs:
(3, 1800)
(6, 3600)
(9, 5400)
We find the slope of the line between these points. The formula for slope is:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Using the first two points, we have:
![m=\frac{3600-1800}{6-3}=\frac{1800}{3}=600](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B3600-1800%7D%7B6-3%7D%3D%5Cfrac%7B1800%7D%7B3%7D%3D600)
To verify Matthew saves the same amount each month, we will find the slope between the second two points and make sure they're the same:
![m=\frac{5400-3600}{9-6}=\frac{1800}{3}=600](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B5400-3600%7D%7B9-6%7D%3D%5Cfrac%7B1800%7D%7B3%7D%3D600)
Matthew's rate is $600 per month.
This is higher than Christopher's by 600-550=$50 per month.
If the variable x is a positive integer, the list of possible values of x can be represented as; x >=1.
<h3>Positive integers</h3>
According to the question;
- We are required to list the possible values of x provided the variable x is a positive integer.
On this note, the list of possible values of x is all numbers greater or equal to 1 in which case these numbers do not have a fractional component.
