Answer:
35%
Step-by-step explanation:
Percent increase is (new number - old number) / old number
(162 - 120) / 120 = 42 / 120 = 0.35 = 35%
Answer:
12 inches of wire
Step-by-step explanation:
Given:
- 14 in = $0.60
- x in = $0.48
Solve:
Set up a proportion to solve this equation. We can find the price for 1 inch first.
- Solve for 1 inch
- 15 in = $0.60
- 1 in = $0.60 / 15
- 1 in = $0.04
Now, we know that 1 inch of wire costs $0.04. We can solve for the x inxhes:
- Solve for x inches
- x in ·$0.04 = $0.48
- x in = $0.48 ÷ $0.04
- x in = 12
- x = 12
You can buy 12 inches of wire.

You can see a common ratio between the terms of the sequence.
Start with 3.
If you multiply that by -1/3, you get -1.
Multiply -1 by -1/3 again and you get 1/3.
Clearly, the common ratio is -1/3.
Thus, the sequence is geometric.
2) Start with -2, and continue to multiply it by -5/2.
1: -2
2: 5
3: -25/2
4: 125/4
Thus, the answer is d.
If 7% interest is compounded annually, then the value of the $500
after 'Y' years in the future is
$500 (1.07)^to the 'y' power .
For this exercise, it's $500 (1.07)⁴ = $ <u>655.40</u> .
