Find the surface area and show work

Law Incorporation [45]

Answer: $1,270in^2$

Step-by-step explanation:

The surface area of a rectangle can be calculated with:

$Area_{rectangle}=lenght*width$

The surface area of a trapezoid can be calculated with:

$Area_{trapezoid}=\frac{height}{2}(Larger\ base+Smaller\ base)$

Calculate the area of the base, wich is a rectangle:

$A_{1}=(34in)(15in)=510in^2$

There are two equal rectangles, therefore, multiply the area of any of them by 2:

$A_{2}=2(15in)(13in)=390in^2$

Calculate the area of the other rectangle:

$A_{3}=(15in)(10in)=150in^2$

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

$A_4=\frac{2(5in)}{2}(34in+10in)=220in^2$

Therefore, the surface area will be the sum of all the areas calculated:

$SA=A_1+A_2+A_3+A_4\\\\SA=510in^2+390in^2+150in^2+220in^2\\\\SA=1,270in^2$

What is the equation of this line? y=−3/2x y=2/3x y=3/2x y=−2/3x Graph of a line passing through the origin and the point begin

iogann1982 [59]

Correct answer: y=(2/3)x

The line passes through the origin (0,0) and the pair (3,2)

the equation y=(2/3)x satisfies both points:

for (0,0): 0=(2/3)*0 = 0

for (3,2): 2 = (2/3)*3 = 2

and therefore is the correct linear function of the line described.
