We have area of the rectangle:

$fg=120$

Area of the triangle:

$\frac 1 2 f \times 3 = 135-120$

Solve away:

$f = \frac 2 3(15) = 10$

$g= \dfrac{120}{f}=12$

Answer: f=10, g=12

Check: trapezoid area

$A = \frac 1 2(12+15)10 = 5(27)=135 \quad\checkmark$

Haley had 56 dollars she spent 5/8 of her money on a new shirt how much money did she have left after buying the shirt

Mrac [35]

First you would multiply $56 by 5/8:

56 * 5/8 = 35

Now you know that she spent $35 on the shirt. So, subtract 35 from 56 and that's your answer.

56 - 35 = 21

Haley has $21 after buying the shirt. :)

the volume of a cylinder is given by the formula v=3.14r^2h, where r is the radius of the cylinder and h is the height. suppose

photoshop1234 [79]

we know that

The volume of a cylinder is given by the formula

$V=3.14 r^{2} h$

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

$r=x+8\\h=2x+3$

Substitute the values in the formula above

$V=3.14*(x+8)^{2}*(2x+3)$

$V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)$

therefore

<u>the answer is</u>

The volume of the can is equal to

$V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}$
