Answer:
4
Step-by-step explanation:
(6√5)²+x²=14²
36(5)+x²=196
180+x²=196
x²=196-180
x²=16
x=√16
x=4

Answer:
19
Step-by-step explanation:
In the first day the population will decrease to 1530, then 1500 the day 2, 1470 day 3, and so on ...
For decrease and get less than 1000 the mold population needs to be reduced in at least 560. The questions turns to be, how many days will it take to reduce the population in 560 spores?
If we divide 560 between 30 it will gives us the answer:
560/30 = 18.667
So, it is need to wait 19 days. In 18 days only 540 spores are reduced. In 19 days 570. We will say 19 days as we are looking (I guess) for an integer number.
Answer:
an estimate is sufficient
Step-by-step explanation:
Assuming the given numbers represent all of the flour Jasper needs, he can estimate that he will need more than 4 cups and less than 4 1/2 cups. It is unlikely that a package of flour will have the exact amount needed, so this estimate is probably sufficient to determine what to buy.
