Answer:
C. 2.5×10^-27
Step-by-step explanation:
(2×10^-13)^-2 = 2^-2 × 10^(13×(-2)) = 1/4 × 10^-26
= 0.25 × 10^-26 = 2.5 × 10^-27
___
Your scientific or graphing calculator can compute and display this for you.
60 blocks in 30 min
18 blocks in 9 min
Method 1
60-18 = 42
42 blocks in 21 min
Method 2
30-9 =21 min
#1) Arrange the numbers from least to greatest.
#2) If there is a odd amount of numbers the middle number is your answer.
but if there is a even amount of numbers, take those two middle numbers, add them, then divide them by two. Then you got your answer.
1/100 is average and it’s a 1/25 chance so it’s a 1/2500
50 / 3 = 5280 / x......50 ft to 3 turns = 5280 ft to x turns
cross multiply because this is a proportion
(50)(x) = (3)(5280)
50x = 15840
x = 15840/50
x = 316.8 pedal turns
