Answer:
You have to invest $6,250
Step-by-step explanation:
very simple applying the simple interest formula which is
Given data
A, final amount = $10,000
P, initial principal balance= ?
r, annual interest rate = 7.5%
t, time (in years)= 8 years
we can substitute our given data to find the principal needed.
Divide both sides by 1.6 we have
P= $6,250
3/8
We can write the entire book with the number 1. Now we can write this operation
3/8 + 1/4 + x = 1
3 + 2 + 8x = 8
5 + 8x = 8
8x = 3
x = 3/8
angle 1 = 84
angle 2 = 6
complementary angles add up to 90 degrees.
angle 1 + angle 2 = 90
(4x + 60) + x = 90
5x + 60 = 90
5x = 30
x = 6
angle 1 = 4x + 60 = 4(6) + 60 = 84
angle 2 = x = 6
$14.85
8.98 + 3.27 + 1.5 = 13.75
13.75 x .08 = 1.1
13.75 + 1.1 = 14.85
18
15-10÷5+5
First distribute the 10 ÷ 5.
15-2+5
Left to right, Subtract the 15-2.
13+5
Add.
