Answer:
Should be 10 if there is nothing for th stem value of 3.
Step-by-step explanation:
The stem is the tens place, and the leaf is the ones. You would get 28 40 43 43 45 50 50 for your numbers. If you take Q3-Q1, you get your answer, 10.
Answer:
The length of DF must be between 21 and 53.
Step-by-step explanation:
In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.
EF + DF > DE
16 + DF > 37
DF > 21
Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.
DE + EF > DF
37 + 16 > DF
53 > DF
With these two in mind, we know that DF must be between 21 and 53
Multiplying -15 by 60 yields -900, so the amount of water in the pool changes by -900 gallons in one hour.
