Marks lawn care company charges a flat fee of $15, plus $9 per half hour for every job. which equation can be used to find the amount Y that marks lawn care company would charge for a lawn job that takes X hours to complete? A. Y=15x+18
B. Y=18x+15
C. Y=15x+9
D. Y=9x+15

y= 18x + 15

Step-by-step explanation:

If its 9 dollars per hour than it would be 18 per hour. The independent variable is the how long itll take, and the 15 would be without starting. So it results into B) y=18x+15

D. (Y=9x+15)

Step-by-step explanation:

This one was pretty easy to find out using common sense, it can be solved via knowing that the only variable being multiplied is 9, so find 9x+15 and there is your answer.

The correct question is:

The product of sin30 and sin60 is the same as the product of.............

Find attachment for the diagram

The product of sin30 and sin60 is the same as the product of cos60 and cos30.

Step-by-step explanation:

First of all, note that the following are correct:

cos60° = 0.5

sin60° = (√3)/2

cos30° = (√3)/2

sin30° = 0.5

sin30 × sin60 = 0.5 × (√3)/2 = 0.43301

Obviously, just by mere inspecrion,we see that

cos60 × cos30 = 0.5 × (√3)/2 = 0.43301

In conclusion, the product of sin30 and sin60 is the same as the product of cos60 and cos30.
