52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x
this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x
stands for the diagonal
x = 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13 X 4 = 52
Answer:
Ron will not make his monthly goal of $4,123 and will need $359.74 to supplement his monthly income when he retires.
Step-by-step explanation:
Given monthly income of Ron is $3,142.23
Ron contributes 10% of his monthly income that is $ 314.223
Given : Ron is 25 years old and is retiring at the age of 65. so he has 40 years to contribute.
Total amount he contribute in 40 years paying 5.5% compounded monthly is given by
interest rate(r) =
time period = 40 years = 480 months
Principal amount = $ 314.223
Future value =
Substitute , we get,
Thus, future value is $547074.681009.
After retirement his monthly income when he has $547074.681009 amount.
Putting values , we get,
P = $3763.25
He will receive a monthly income of $3763.25.
But given he will need a monthly income of $4,123 for 20 years which is not met by Ron.
So,the amount he need to supplement his monthly income when he retires by (4123-3763.25)= $359.74
Ron will not make his monthly goal of $4,123 and will need $359.74 to supplement his monthly income when he retires.
