Kelso / jones = 84.5/33.8 = 5/2 = 2 1/2
==> c
Answer:
One is 3 to 4th power
(3 x 3) x (3 x 3)
Step-by-step explanation:
the other is
3 to 3rd power divided by nine to the fourth power...
(3 x 3) x 3 = 27
(9 x 9 ) x (9 x 9) = 2187
2187 / 27 = 81
Answer:
Step-by-step explanation:
A) Divide both sides of equation by t to isolate r. Then, r = d/t
B) Plugging in the given numbers, solve:
d = distance which is 760,320 yards
r = rate which is unknown
t = time which is 2 hours.
- r = d/t
- r = 760,320 yards / 2 hours
- r = 380,160 yards per hour
C) The conversion from yards to miles, 1 yard = 1760 miles. So, multiply by the previous answer in (B) by the two ratios or just divide:
- 380,160 yards / 1760 miles = 216 miles per hour
D) Use miles in this scenario because of the number of significant digits (yards would require a number in the hundred-thousands).
