If we assume the hypotenuse is of side length 5:
a^2+b^2=c^2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
If the hypotenuse is the unknown:
a^2+b^2=c^2
3^2+5^2=c^2
9+25=c^2
c^2=34
c=(34)^(1/2)
Answer:
After 10 years the cost will be $ 97.52.
Step-by-step explanation:
This problem requires us to calculate the cost of graphing after 10 years if inflation rate is two percent. This can easily be calculated by compounding present value of current cost at the rate of 2%. Detail calculation is given below.
FV= 80 (1+2%)^10
FV = $ 97.52
To write an equation and simplify it, I'll start with this:
$4,500 = $90 + $39X Let X represent the amount of people attending the party.
Subtract 90 and both sides of the equation to make the $39X alone.
$4,410 = $39X
Divide $39 into both sides of the equation to isolate or bring X alone.
113.076923 = X
Now since we have to round down, we will do 113.
Answer: 113 people can attend the anniversary party.
