A) The amount of change is .20 (20 cents) so we need to find what percent of $4.00 is .20...
4 * x = .20
x = .20/4 = .05
Multiply by 100 (move decimal 2 places to the right) to change decimal to percent.
.05 = 5% increase
b)The increase is .75. What percent of 3.00 is .75
3 * x = .75
x = .75/3
x = .25 x 100 = 25% increase
c) The amount of change is .75 but this time we are going from 3.75 to 3.00 so we find out what percent .75 is of 3.75.
3.75 * x = .75
x = .75/3.75
x = .20 x 100 = 20% decrease
Hei
Here it is
-4-5=-9
-4x(-5)=20
Answer:
1. 4x5÷3 is a pair with 4x3÷5
2. 5x 4/3 is a pair with 5x3÷4
3. 3x 5/4 is a pair with 4x 3/5
Answer:

Step-by-step explanation:
We know that
Length(l) = 1.5n + 9 ft
Width(w) = 5n - 1.5 ft
The formula for the perimeter(P) of a rectangle is:

So by substituting l and w we get :
![P= 2[(1.5n+9)+(5n-1.5)]](https://tex.z-dn.net/?f=P%3D%202%5B%281.5n%2B9%29%2B%285n-1.5%29%5D)
![P= 2[(1.5n+9)+(5n-1.5)]](https://tex.z-dn.net/?f=P%3D%202%5B%281.5n%2B9%29%2B%285n-1.5%29%5D)
![P= 2[1.5n+5n+9-1.5]](https://tex.z-dn.net/?f=P%3D%202%5B1.5n%2B5n%2B9-1.5%5D)
![P= 2[6.5n+7.5]](https://tex.z-dn.net/?f=P%3D%202%5B6.5n%2B7.5%5D)

Volume of cylinder is = πr2h
Criteria: π=3.14
By solving,
= πr2h
=3.14x8x8x25
By multiplying, we get,
=5024 cm^2
