A. To be able to have the 2 sides ( the 2 triangles) line up correctly, Net A would be the correct one.

B. AB = 3

BC = 5

CD = 9.4

C. Surface area:

9.4 x 5 = 47

9.4 x 3 = 28.2

9.4 x 4 = 37.6

3 x 4 = 12

Total: 47 + 28.2 + 37.6 + 12 = 124.8 sq. in.

Riley and Erik have earned a total of 135 tokens to buy items in the school store. The ratio of the number of tokens that Riley

lisabon 2012 [21]

Answer:

<em>Riley has 72 tokens</em>

Step-by-step explanation:

<u>System of Equations </u>

We have two conditions for the tokens Riley and Erik have earned. Let's call x and y to the number of tokens of Riley and Erik respectively. The first condition states that

$x+y=135$

Solving for y

$y=135-x$

The second condition is that the ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7. It's written as

$\displaystyle \frac{x}{y}=\frac{8}{7}$

Or equivalently

$7x=8y$

Replacing y from the first equation

$7x=8(135-x)$

Operating

$7x=1080-8x$

Simplifying

$15x=1080$

$\boxed{x=72}$

Riley has 72 tokens

A cereal box has a height of 32 centimeters. it has a base with an area of 160-square centimeters. What is the volume,in cubic c

lutik1710 [3]

Volume=legnth times widht times height
legnth times width=area of base
so
volume=area of base times height for a prism

area of base=160
height=32
volume=160 times 32
volume=5120

volume is 5120 cubic centimeters or
5120 cm^3

What is the equation of a vertical line passing through the point (-4, 7)?

MrRa [10]

Answer:

x=-4

Step-by-step explanation:

Since we know that the equation will be x= we will just have to take the x value of the coordinate point and that would be the x so in this case the x is -4 so the equation would be x=-4
