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.
So how you would answer this question is by finding the area of the sides. So the rectangle is 25 x 17 or 425 and there is 4 rectangles. You take the area of the rectangle and multiply it by 4, which would be 1700 and now you find the area of the square which is 17 x 17 or 289 and then you multiply that by 2 because there are two squares, 578 and you take that answer and put it with the area of the rectangles and you get your surface area. 2278 is the surface area of the rectangular prism. Another way to explain it is there are 6 sides so six areas and you just add the areas together to get the surface area. Hope this helps :D
Answer:
line equals 180 full circle equals 360 therefore .. you add the three numbers once gotten your answer subtract that from 180 which would be 180-135=45 degrees
Answer:
Step-by-step explanation:
Given
Probability that an inspector doe not identify low-quality timber=0.20
(a)Probability that both inspector do not identify a low quality timber
(b)Let n be the no of inspector
Probability should be less than 1%=0.01
so 
Taking 
both sides
x>2.861
thus minimum value of x is 3
(c)From part b it is clear that minimum 3 officer are required to to keep the low quality timber below 1%
on an average 2 officer are not sufficient to identify 4 low quality timber out of 100
