The square pyramid has a volume of 486 cubic inches. What is the value of x?
Softa [21]

Volume of square pyramid can be calculated by the formula :

V=a^{2}\frac{h}{3}

a is the length of base and h is the height of the pyramid.

In the given figure a= x in.and h = \frac{1}{4}  x in.

Volume of pyramid given V =486 cubic inches.

Substituting these values in volume of pyramid we have:

486= x^{2}  \frac{x}{4} ÷ 3

Or 486=\frac{x^{3}}{4}  x\frac{1}{3}

486= \frac{x^{3}}{12}

Multiplying both sides by 12

5832 =x^{3}

18^{3}  =x^{3}

Or x= 18 in.

Assuming a motorcycle traveled 80 miles in 5 hours at a constant speed, How far did it go in 1 hour?
Serggg [28]

Answer:

16 miles

Step-by-step explanation:

We can write the ratio of miles:hours as 80:5 using the given information. Because we want to find the distance of 1 hour, we can divide the ratio by 5 (because 5/5 is 1, and we want 1 on the "right side") which gets us 16:1. This means that the motorcycle traveled 16 miles in one hour. Hope this helps!
