There are 8 because
5³ ⇒ 125
There are 1000 cubic inches.
And 1000 ÷ 125 ⇒ 8

Answer:
36 mph
Step-by-step explanation:
The appropriate relations are ...
time = distance/speed
speed = distance/time
Suppose the race has a total length of 360 miles. Then half the race is 180 miles.
The cyclist's time on the first half is (180 mi)/(30 mi/h) = 6 h.
The cyclist's time on the second half is (180 mi)/(45 mi/h) = 4 h.
The total time is 10 h for the total distance of 360 mi, so the average speed is ...
(360 mi)/(10 h) = 36 mi/h
_____
The length of the race doesn't matter. The above numbers make the math convenient. The average is computed from ...
1/((1/2)/30 + (1/2)/45) = 2/(1/30 +1/45) = 2·30·45/(30+45) = 36
This is the <em>harmonic mean</em> of the numbers 30 and 45.
Hello, To solve this problem, you need to use a process of trial and error, and add up each number until you get 24 or above. If you get above, it is wrong. The only number that goes into 24 evenly is 8, so the answer is 8 keychains.<span>

Step-by-step explanation:
"If the sum of 2 angles is 180°, then each is the supplementary angle of the other".
