Answer:
325 minutes
Step-by-step explanation:
We can use a ratio to solve
25 minutes x minutes
------------------ = ---------------
1 burger 13 burgers
Using cross products
25*13 = 1x
325 = x
325 minutes
Answer:
Solve for a
A= 3/B - 2
Step-by-step explanation:
Answer:
2/3 magazines per hour
Step-by-step explanation:
Olivia writes 2 new sheets of magazines in 3 hours.
The rate per hour at with she writes the sheets of magazines is the number of sheets divided by the amount of time taken to write the sheets.
Hence, the rate per hour is:
R = 2 / 3 = 2/3 magazines per hour
The rate per hour at with she writes the sheets of magazines is 2/3 magazines per hour.
Total number of Marbles is = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12.
P( Not yellow) 12/20 = 3/5.
<h3>The answer is 3/5.</h3>
The annual interest rate needed to reach the given amount in five years is 4.47%.
Hence, option B) is the correct answer.
<h3>What is the annual interest rate needed?</h3>
Compound interest is expressed as;
A = P( 1 + r/n )^(nt)
Making rate r the subject of the formula;
r = n[ (A/P)^(1/nt) - 1 ]
Given that;
- Principal P $2000
- Final Amount A = $2500
- Number of times interest applied per time period n = monthly = 12
- Time t = 5
We substitute into our formular above
r = n[ (A/P)^(1/nt) - 1 ]
r = 12[ (2500/2000)^(1/(12×5)) - 1 ]
r = 12[ (1.25^(1/60) ) - 1 ]
r = 12[ 1.0037598 - 1 ]
r = 12[ 0.0037598 ]
r = 0.447
Next we convert to percentage
r = 0.447 × 100%
r = 4.47%
The annual interest rate needed to reach the given amount in five years is 4.47%.
Hence, option B) is the correct answer.
