Answer:
9.45
Step-by-step explanation:
2.70*3 = 8.10
8.10 + 1.35= 9.45
3*(x+5)^(1/2)=-9
(x+5)^(1/2)=-3
x+5=9

Answer: 120
"A analog clock is diveded up into 12 sectors, based on the numbers 1-12. one sector represents 30 degrees (360/12=30). if the hour hand is directly on the 10, and the minute hand is on the 2, that means there are 4 sectors of 30 degree between then, thus they are 120 degree apart (30*4=120)."
