Answer:
20%
Step-by-step explanation:
First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
Answer:
h = 39
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume is 10000pi and the diameter is 32
The radius is 32/2 = 16
10 000 pi = pi (16)^2 h
Divide each side by pi
10 000 pi/pi = pi/pi (16)^2 h
10 000= 256 h
Divide each side by 256
10000/256 = 256h/256
39.0625 = h
To the nearest whole number
h = 39
Answer:
15/18
Step-by-step explanation:
A single di has 6 sides, meaning the probability of rolling a 6 is 1/6. So if you roll a di 18 times you would probably get 6 three times. Meaning the number of unsuccesful rolls would be (18/18 - 3/18). Hope this helps.
