8. Crystal earns $5.25 per hour mowing lawns.
a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 2 hours and 15 minutes?

A. m(h) = h/5.25; $0.43

B. m(h) = 2h +15; $25.50

C. m(h) = 5.25h; $11.81

D. m(h) = 5.25h; $11.29

C. m(h) = 5.25h; $11.81

Step-by-step explanation:

Crystal will earn $11.81.

Step-by-step explanation:

Since we have given that

Cost per hour mowing lawns = $5.25

Let the number of hours be 'h'.

Let the amount of money be 'm'

So, According to question, we get

Here h = 2 hours and 15 minutes

So,

So, Crystal will earn if she works for 2 hours and 15 minutes will be

Hence, Crystal will earn $11.81.

step-by-step explanation:

then i will answer

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
