Answer:

The total change in his account is of -$85, that is, a loss of $85

Step-by-step explanation:

We combine these changes. So

On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.

On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70

On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85

Please help ! This is 7th grade math and I’ve been stuck on this question for 30 minutes!
FinnZ [79.3K]

\dfrac{1}{22}\:\dfrac{\text{in}}{\text{hr}}

Step-by-step explanation:

The amount of time from 10pm to 7am is 9 hours. However, the time indicated is 7:10am. Since there are 60 minutes in an hour, 10 min is equal to 1/6 of an hour. Therefore, the total time that the water level of the pool decreased is 9\frac{1}{6} hours or \frac{55}{6} hours. To find the rate at which the water level decreased, we divide the change in the water (in inches) by the time it took to reach that level. So we write

rate of change = \dfrac{\text{change\:in\:height}}{\text{change\:in\:time}}

\:\:\:\:\:\:\:= \dfrac{\frac{5}{12}\:\text{in}}{\frac{55}{6}\:\text{hrs}}

\:\:\:\:\:\:\:=\dfrac{5}{12}\cdot\dfrac{6}{55}\:\dfrac{\text{in}}{\text{hr}}

\:\:\:\:\:\:\:= \frac{1}{22}\:\dfrac{\text{in}}{\text{hr}}
