Answer:
9 hours
Step-by-step explanation:
We can use a ratio to solve
819 miles 567 miles
-------------- = --------------
13 hours x hours
Using cross products
819 x = 567*13
Divide each side by 819
819x/819 = 567*13/819
x =9
7+7=14. You can draw pictures, count on your hands, etc.

Answer:
262.44 cubic metres.
Step-by-step explanation:
First, we can calculate the volume of the cylinder by doing pi * r^2 * h. In this case, r is 5 / 2 and h is 7.
pi * (5/2)^2 * 7 = pi * 25/4 * 7 = pi * 6.25 * 7 = pi * 43.75 = 3.14159265 * 43.75 = 137.4446784 cubic m.
Seconds, we calculate the volume of the cube. It is 5^3 = 5 * 5 * 5 = 25 * 5 = 125 cubic m.
137.4446784 + 125 = 262.4446784, which is about 262.44 cubic metres.
Hope this helps!
