Answer:
540
Step-by-step explanation:
We need 6 times 90 for the full amount.
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
4 x ? = 252
Do the opposite of multiplication.
252 ÷ 4 = ?
? = 63.
Hope this Helps! :)
Answer:
C =37.68 m
Step-by-step explanation:
The formula for a circumference is given by
C = pi *d
C = 12 pi
Approximating pi = 3.14
C = 12*3.14
C =37.68 m
Answer:
10^-5 or 1/100,000
Step-by-step explanation:
That probability of 5 events in a row is the 5th power of the probability of one of them, assuming they are independent.
0.1^5 = (10^-1)^5 = 10^-5
