The correct awnser would be B because it is the only one rounded to the nearest cent
Answer:
Given:
5 pounds rice cost $2.49
To Find:
Cost of 9 pounds rice
Step-by-step explanation:
5 pounds rice cost $2.49
1 pound rice will cost $
So,
9 pounds rice cost = 1 pound rice cost × 9
= $
= $0.498 × 9
= $4.482
I would go withhh c but I am not 100% sure
(12+7x)(12-7x)
Because the square root of 144 is 12 and for 49 is 7
The formula that calculates the compound rate from the given values is
<h3>How to determine the compound interest rate?</h3>
The compound interest formula is:
Where:
- P represents the principal amount
- r represents the compound interest rate
- n represents the number of times the interest is compounded
- t represents the time in years
- I represents the interest
We start by adding P to both sides
Divide through by P
Take the nt-th root of both sides
Subtract 1 from both sides
Multiply through by n
In this case, t = 10
So, we have:
Hence, the formula that calculates the compound rate is
