An infinite geometric series is the sum of an infinite geometric sequence . This series would have no last term. The general form of the infinite geometric series is a1+a1r+a1r2+a1r3+... , where a1 is the first term and r is the common ratio. We can find the sum of all finite geometric series.
3 periods, 20 minutes each
20 * 3 = 60 minutes
12 minutes per period
12 * 3 = 36
So the ratio is 36:60, or simplified: 3:5
Answer:
y=-13/3x+11/3
Step-by-step explanation:
(1.5-0.2)/(0.5-0.8)=1.3/-0.3=-13/3
-13/3(0.5)+b=1.5
b=11/3
Answer:
18
Step-by-step explanation:
6 divided by 2 = 3 + 8 = 11
11 x 2 = 22 - 4 = 18
Hope this helps! :>
We are given that car dealership employed 4 mechanics. and 20 cars came there.
That means each employee should handle 
Which means we need to choose 5 cars from 20 cars first . For that we need to use combinations since order in which car is given to mechanic does not matter.
Hence number of ways =
=
= 15504 ways of allocating.
