For number 13 x=70 and y=115 hope this helped
Answer:
60°
Step-by-step explanation:
∠B=(240-120)/2=120/2=60°
Answer:
C
Step-by-step explanation:
Possibly F also, if that is a multiplication dot in between
100 / 9
They both equal 11.11
(70/21)^2 * 8^3 * (1/2^9)
Since the buses travel in opposite directions, the speed at which they distance themselves is the sum of their speeds.
One bus travels at speed s.
The other bus travels at speed s + 15.
The sum of the speeds is s + s + 15 = 2s + 15
speed = distance/time
distance = speed * time
366 = (2s + 15) * 2
183 = 2s + 15
168 = 2s
s = 84
The slower bus travels at 84 km/h.
s + 15 = 84 + 15 = 99
The faster bus travels at 99 km/h.
Check:
In 2 hours, the slower bus travels 2 * 84 km = 168 km
In 2 hours, the faster bus travels 2 * 99 km = 198 km
In 2 hours, the buses are 198 km + 168 km = 366 km apart.
Our answer is correct.
