Between 9 AM and 6:10 AM the water level in a swimming pool decreased by 5/12 inches assuming that the water level decreased at a constant rate how much did the water level drop each hour?

The water level drops each hour by 0.1472 inches/hour.

Step-by-step explanation:

We are given that Between 9 AM and 6:10 AM the water level in a swimming pool decreased by 5/12 inches assuming that the water level decreased at a constant rate.

Firstly, we will find the number of hours between 6:10 AM and 9 AM, that is;

Number of hours = From 6:10 AM and 9 AM, there are 2 hours and 50 minutes

So, Number of hours = = 2.833 hours

Also, the water level in a swimming pool decreased by = = 0.417 inches

Now, to find how much did the water level drop each hour, we will divide the amount of water level in a swimming pool decreased by the time interval given, that is;

=

= 0.1472 inches/hour.

This means that the water level drops each hour by 0.1472 inches/hour.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
