Answer:
523.33 in³
Step-by-step explanation:
Volume = (4/3)×3.14×5³
= 523.3333333333 in³
(4 2/3) / (4 1/5) = 1.111
mark is 26=x and marissa id 33
if you take 59 take away 7 you get 52
then you wil devide 52 and get 26
you will use the 7 you took out earlier and add it to one of the 26 which will give you mark(26=x) and marissas(33) age .
The age of victor after 3 years is 24.
Option: C
<u>Step-by-step explanation:</u>
Mr.Smith is 81 years older than victor.
After 3 years Mr.smith will be four times of victor's age.
⇒After 3 years, age of Mr.Smith will = 81+3.
∴After 3 years, age of Mr.Smith will be 84.
Let us consider victors age as x.
We know that four times of victor's age = Mr.Smith's age after 3 three years.
⇒4x=84.
x=![\frac{84}{4} .](https://tex.z-dn.net/?f=%5Cfrac%7B84%7D%7B4%7D%20.)
x=21.
So we found that age of Victor is 21 and further we have to find his current age. i.e. his age after 3 years.
Victor's current age =21+3.
=24.
∴ The victor's current age is 24 years old.
The first term is a = 72
The common ratio is r = 1/6.
We multiply each term by 1/6, which is the same as dividing each term by 6.
To find r, divide any term you want over the previous term
r = 12/72 = 1/6
r = 2/12 = 1/6
etc.
Now use the infinite sum formula to find S
S = infinite sum
S = a/(1-r) ... see note below
S = 72/(1-1/6)
S = 72/(6/6 - 1/6)
S = 72/(5/6)
S = (72/1) divided by (5/6)
S = (72/1)*(6/5)
S = (72*6)/(1*5)
S = 432/5
S = 86.4
Answer: 86.4
note: this infinite sum formula only works if -1 < r < 1. In the case of r = 1/6 = 0.167 (approx), this r value is between -1 and 1.
