Response:
The investment's value after 3 years will be £11,904
Step-by-step explanation:
sarah invests £9600 with an 8% simple interest rate per annum
Duration is 3 years
Formula for simple interest
I = P*n* r
P is the initial investment= 9600
r signifies interest rate = 8% = 0.08
n = duration in years = 3
Now, we can calculate the interest using the formula
I = 9600 * 0.08 * 3= 2304
The interest accrued totals 2,304
Now, we combine the interest with the initial investment to find the investment's total value after 3 years
9600 + 2304= 11904
Answer:
In conclusion, the answer is C.
Step-by-step explanation:
<span>The question requires us to calculate: 13/56 + 5/7. To solve this, we must first identify a common denominator for these fractions, which we find to be 56 as 56 = 7 * 8. We then multiply both the numerator and denominator of the second fraction by 8. This gives us 5/7 * 8/8 = 40/56. Lastly, we add the fractions: 13/56 + 40/56 = 53/56, and this is the final result, which cannot be further simplified. Answer: 53/56</span>
Answer:
53 teachers
Step-by-step explanation:
First, we need to determine how many teachers are required. If the school district serves 6,734 students with a maximum class size of 25, then the number of teachers needed can be calculated as:
6,734 / 25 = 269.36
Since we cannot have a fraction of a teacher, we must round our result to the nearest whole number (269 or 270).
Taking 269 teachers with 25 students per class results in:
269 • 25 = 6,725 students, which is insufficient, given there are 6,734 students.
This indicates that at least 270 teachers are necessary.
Since there are already 217 teachers, it implies that 270 - 217 = 53 additional teachers are required.
