36/x=100/25
(36/x)*x=(100/25)*x 
36=4*x 
36/4=x 
9=x 
x=9

Hi

x is 100%
9 is 25%

x/100 = 9/25
25x = 100(9)
25x = 900
x = 900/25
x = 36

Answer:

25% of 36 is 9

The top of a table is in the shape of a trapezoid. It has a height 1.5 feet and the two parallel bases measure 3 feet and 5 feet

Kobotan [32]

The area of a trapezoid if found using the formula

A = (base1 + base2)/2 x height

Area = (3+5)/2 x 1.5

Area = 8/2 x 1.5

Area = 4 x 1.5

Area = 6 square feet.

Hey!

------------------------------------------------

Points:

(-2, 3) and (3, 0)

------------------------------------------------

Find the slope:

$= \frac{y2 - y1}{x2 - x1} \\=\frac{0 - 3}{3 - (-2)}\\= \frac{-3}{5} or -0.8$

------------------------------------------------

Slope Intercept Form:

y = mx + b

m = slope

b = y-intercept

Slope = -3/5

Y-intercept = 9/5

Answer: y = -3/5 + 9/5

------------------------------------------------

Point Slope Form:

y - y1 = m(x - x1)

You can use either of the points.

Answer:

y - 3 = -3/5(x - 2)

y - 0 = -3/5(x - 3)

------------------------------------------------
