Answer: B)1,047 feet
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the circumference of the tire:
Circumference(C): π x diameter
C = π (20) = 62.83 inches.
Since 1 foot is equal to 12 inches.
62.83 ÷ 12 = 5.23 feet
Finally we have to multiply the result by 200:
5.23 x 200 = 1,047 feet

Answer:
Step-by-step explanation:
perimeter=2(85)+π(12.5)=220+2×12.5π
=170+25×3.14
=170+78.5
=248.5
distance ran=3×248.5=745.5 yards.
Answer:
A) 10x + 8 = 21
B) x = 1.3
Step-by-step explanation:
2(2x + 3) + 2(x + 1) + 4x = 21
4x + 6 + 2x + 2 + 4x = 21
10x + 8 = 21
10x = 13
x = 1.3 cm
Answer:
83.79 kJ
Step-by-step explanation:
The potential energy is the product of weight and height, where weight is in newtons.
PE = Mgh = (190 kg)(9.8 m/s^2)(45 m) = 83,790 J
