Answer: since you are in middle school, I will assume simple shapes such as rectangles and squares

area=legnth times width
therefor
width=area/legnth and
legnth=area/width

A blimp travel 300 miles in 7.5 hours. Assume the blimp travel at a constant speed. Write and solve an equation to find the speed of the blimp. Use the formula d= rt.

Answers

Well um, I don't know what the d = rt formula is but I know one that would work well with this problem.

Formula for speed = Distance / time

So we have 300 miles as our distance and 7.5 hours as our time.

Then we divide ---> 300/7.5

And that gives us...

40 mph

253+98 then subtract 27

you would do 253-98=155 which equals red , then 155-27=128 which equals blue , the you know that there are 253 yellow , lastly you would do 253+155+128=536 gum balls in the machine

Look at this prism and its net. Rectangular prism with length labeled 5 meters, width labeled 7 meters, and height labeled 12 meters. Net of the same rectangular prism with the same dimensionsn labeled. What is the surface area of this rectangular prism?

Answers

There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

$A_(surf)=2*(l * w)+2*(l * h)+2*(h * w)$
$A_(surf)=2*(5*7)+2*(5*12)+2*(12*7)$
$A_(surf)=2*35+2*60+2*84$
$A_(surf)=70+120+168$
$A_(surf)=358$
$A_(surf)=358m^(2)$

A cube has a volume of 1/512 cubic meter.What is the length of each side of the cube?Explain your thinking.

Answers

The side of the cube will be equal to s = ( 1 / 8).

What is volume?

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of cube or cubes.

The volume of a cube is equal to V = s³

Given a volume of 1/512, using the formula.

V = s^3

1/512 = s³

s = ∛1/512

s = 1/8 meter

Therefore the side of the cube will be equal to s = ( 1 / 8).

The volume of a cube is equal to V = s^3.
Given a volume of 1/512, using the formula.
V = s^3
1/512 = s^3
s = cuberoot of 1/512
s = 1/8 meter
