If they are all a foot long then she should have 32 pieces of Chain
Answer:
C. 8 inches wide and 15 inches long
Step-by-step explanation:
20 x 10 equals 200, so that means the only option that also equals 200 when multiplied togethor is C.
Let´s:
t=time when the both runners coincide.
velocity=distance/time ⇒ distance=velocity x time
distance traveled by Christy=0.12 t
distance traveled by Cindy=0.22 t
Becuse Christy starts the race with an advantage of 1.5 km de distance from Cindy´s position the distance would be : 0.12 t + 1.5
We would have to solve the following equation:
0.12t+1.5=.0.22t
0.22t-0.12t=1.5
0.1t=1.5
t=1.5/0.1
t=15
Answer: In 15 minutes Cindy will catch Christy
Answer:
13
Step-by-step explanation:
(x + 3)^3/2 = 64
√(x + 3)^3 = 64
(x + 3)^3 = 64^2
(x + 3)^3 = (4^3)^2
(x + 3)^3 = (4^2)^3
Same exponent
So
x + 3 = 4^2
x + 3 = 16
x = 13
