Answer:
195.25
Step-by-step explanation:
Consider geometric series S(n) where initial term is a
So S(n)=a+ar^1+...ar^n
Factor out a
S(n)=a(1+r+r^2...+r^n)
Multiply by r
S(n)r=a(r+r^2+r^3...+r^n+r^n+1)
Subtract S(n) from S(n)r
Note that only 1 and rn^1 remain.
S(n)r-S(n)=a(r^n+1 -1)
Factor out S(n)
S(n)(r-1)=a(r^n+1 -1)
The formula now shows S(n)=a(r^n+1 -1)/(r-1)
Now use the formula for the problem
The third one because its the only one decreasing
Answer:
35
Step-by-step explanation:
Maneesha: 75 % × 37 sunflower seeds equals to 27.75
27.75 is a decimal so rounded off they become 28
her friend: 1/3 × 21 = 7 pumpkin seeds
the total of the seeds will be 28 + 7 = 35 seeds

Answer:
The number of ways to select 5 diamonds and 3 clubs is 368,082.
Step-by-step explanation:
In a standard deck of 52 cards there are 4 suits each consisting of 13 cards.
Compute the probability of selecting 5 diamonds and 3 clubs as follows:
The number of ways of selecting 0 cards from 13 hearts is:

The number of ways of selecting 3 cards from 13 clubs is:

The number of ways of selecting 5 cards from 13 diamonds is:

The number of ways of selecting 0 cards from 13 spades is:

Compute the number of ways to select 5 diamonds and 3 clubs as:

Thus, the number of ways to select 5 diamonds and 3 clubs is 368,082.
Answer:
70 degrees
Step-by-step explanation:
Because an area of a triangle is 180.
55 + 55 = 110 180 - 110 = 70
110 + 70 = 180
