N(1/5) = (2/15)
divide both sides by (1/5)
n = (2/15)/(1/5)
to divide fractions, cross multiply, e.g. (2*5)/(15*1) = 10/15
n = 10/15 = 2/3 or 0.666666.
Average speed=(total distance traveled)/(total time of travel)
average speed=(120+48)/3
average speed=56 mph
80085 because this is the circumference which u multiply across surface area that gives u the volume.
Answer:
3:4
Step-by-step explanation:
You divide both sides by 2: 6/2:8/2=3:4.
Consecutive odd or even integers are of the form x, x+2.
So we have x(x+2) = 63, where Diane's age = x.
x²+2x = 63.
x² + 2x - 63 = 0
(x + 9)(x - 7) = 0
x = -9, or 7.
Since -9 is awfully young, we rule it out and say Diane's age is 7, and her sister is 9.
