Let width be x
let length be x+13
perimeter=2*(L+W)
226=2*(x+x+13)
226=2*(2x+13)
226=4x+26
subtract 26 from each sides
200=4x
x=50, which is the width
length=63
5:2 is basically the same as 14:35
To get to 5 you have to multiply 2 by 2.5 and 14 times 2.5 is 35
Answer:
The expression is equal to ![3.50h+4](https://tex.z-dn.net/?f=3.50h%2B4)
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to
![m=\$3.50\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%243.50%5C%20per%5C%20hour)
The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute
![y=3.50x+4](https://tex.z-dn.net/?f=y%3D3.50x%2B4)
For x=h hours
substitute
![y=3.50h+4](https://tex.z-dn.net/?f=y%3D3.50h%2B4)
Hello!
The mean is 12
The data has a standard deviation of 4
Look and see how far away 18 is from 12 using 4
12 + 4 = 16
16 is one deviation
16 + 4 = 20
20 is two deviation
18 is right in the middle
The answer is C. 1.5 deviations
Hope this helps!
7 by 8 rectangle plus a 7 base by 11 - 8 height triangle
A = 7×8 + (1/2) 7 (11 - 8) = 56 + 21/2 = (112+21)/2 = 133/2
