To find the circumference of a semi-circle, it would be 1/2<span> π × d. So, pi (3.14) times the diameter, 5 would be 15.7, but then we would need to multiply it by 1/2 to get the circumference for half the circle, and that will get you 7.85. Now you can add all the lengths now. 7.85 + 7 + 5 + 7 = 26.85. Hope this helps! Let me know if you still don't get it. <3</span>
Answer: The answer is that he cleaned one room
Step-by-step explanation:
Because he charged in total 77 dollars and he charged 77 dollars per room, so 77*1=77=c
In order from left to right:
D, C, A, B
Solve for m by simplifying both sides of the equation, then isolating the variable.
m = -2.5
Interest = PRT/100
I= 14000*0.12*3
I=5040
Add Interest to the Principal
14000 + 5040
= $19,040
A is the answer.
