Answer:
0.508
Step-by-step explanation:
Since you have to multiple. L×W×H....
The first one has a volume of 400 and the second has a volume of 400...so both prisms have an equal volume but have a differnet shape
This means 900÷1000 because 10 to the power of 3 is 1 and 3 zero which is 1,000. The answer will be 0.9
The length of the yard is 25ft.
In order to find this we first need to set up variables for the length and the width. Since we don't know anything about the width, we'll set it as x. Then, we know the length is equal to ten more than three times the width. Since the width is x, we can write the length as 3x + 10. Now we can use the formula for the perimeter of a rectangle to solve for x.
2l + 2w = P
2(3x + 10) + 2(x) = 60
6x + 20 + 2x = 60
8x + 20 = 60
8x = 40
x = 5
Now that we have a value for x, we can plug into the length equation and find the length.
3x + 10
3(5) + 10
15 + 10
25
You would multiply 2.75 by 50, which is 137.5 miles
