The common endpoint of two Amy's is the vertex. So the answer is A
Answer:
Yes
Step-by-step explanation:
25.12 inches of circumference is equal to the radius of 3.998 inches
4 inches > 3.998 inches
Therefore it fits
10x = 5 Answer: x = 1/2
−5 = x + 6 Answer: x = -11
22 = 22x Answer: x = 1
0 = −7x Answer: x = 0
−x = 7 Answer: x = -7
x/4 = 1/2 Answer: x = 2
x/5 = 20 Answer: x = 100
x/-2 = -5 Answer: x = 10
5x = 55 Answer: x = 11
−3x = 18 Answer: x = -6
12 = x -6 Answer: x = 18
A]
D=R×t
d=5.8r
d2=5.1(r+7)
0.7r=35.7
r=51 mi/hr
thus the average speed on the outbound trip would be:
51+7=58 mi/hr
b]
let speed of fishing boat=x km/h
speed of cruise ship=(x+12.5) km/h
distance traveled by fishing boat=11.5×x=11.5x km
distance traveled by cruise ship=(x+12.5)×11=(11x+137.5) km
Total distance covered by the ships:
11.5x+11x+137.5=322
22.5x=322-137.5
22.5x=184.5
thus
x=184.5/22.5
x=8.2 km/h
The speed of fishing boat is 8.2 km/hr
