Bella worked for 15 days for a total of 112.5 hours. how many hours did she average per day?

7.5

Step-by-step explanation:

So, we want to take the hours in the fifteen days. 112.5, and divide that by 15 days to get how many hours per day, which is 7.5.

Check:

7.5 * 15 = 112.5

112.5 = 112.5

112,5 : 15 = 7,5

Bella worked 7,5 h daily

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
