Answer: 1st train = 364 mph, 2nd train = 356.2
Step-by-step explanation:
Train 1: x + 7.8
Train 2: x
Train 1 + Train 2 = Sum
x + 7.8 + x = 720.2
7.8 + 2x = 720.2
2x = 712.4
x = 356.2
Train 1: x + 7.8
= 356.2 + 7.8
= 364

Answer:
C) 9
Step-by-step explanation:
54 = 2 x 3 x 3 x 3
81 = 3 x 3 x 3 x 3
common factor of 54 and 81 = 3 x 3 = 9
Answer: 9
Central angle = 360 / 24 = 15 degrees
ARc length = r * theta, where theta is the angle in radians and r = radius
= 15 * 15 * pi/180
= 3.93 feet to nearest hundredth.
Area of sector = area of circle / 24 = pi*15^2 / 24 = 29.45 ft^2
Answer:
237
Step-by-step explanation:
multiply the length value by 10
