Answer
using fethagorth equation
Step-by-step explanation:
To figure out one measure of a triangle, we use A2+B2=C2
(Where a is the first measure times itself, b is the second side times itself and c is the longest side times itself). Once you figure that out and plug all your numbers into the formula, you can solve like a regular equation. 45 times 45 is 2,025. 85 times 85 is 7,225. We don't know c so we just put that as C2. Our equation- 2,025+7,225= C2
Add the numbers to get 9,250= C2
Our answer is 96. (Because 96 times itself is 9,250). The answer is not exact so I just rounded it to the nearest whole number.
Answer:
- 7% interest = $10,000
- 13% interest = $20,000
Step-by-step explanation:
First find out what an 11% return on $30,000 is.
= 11% * 30,000
= $3,300
Use simultaneous equations.
Assume the amount to be invested in to make a 7% interest is x and the amount for a 13% interest is y.
0.07x + 0.13y = 3,300
x + y = 30,000
y = 30,000 - x
0.07x + 0.13 (30,000 - x) = 3,300
0.07x + 3,900 - 0.13x = 3,300
0.07x - 0.13x = 3,300 - 3,900
-0.06x = -600
x = -600 / -0.06
x = $10,000
y = 30,000 - x
= 30,000 - 10,000
y = $20,000
