Step-by-step explanation:
The percentage error for the given data will be 12.5%
What is the percentage?According to its definition, a percentage is any number relative to 100. It is shown with the sign %. "Out of 100" is what the percentage means. Consider dividing any quantity or item into 100 identical bits.
The percentage error will be calculated as:-
percent error = (|experimental value - theoretical value| / theoretical value) x 100
In this case, the experimental value is 3600 years (from carbon-14 dating) and the theoretical value is 3200 years (from the researcher's estimate). Plugging these values into the formula:
percent error = (|3600- 3200| / 3200) x 100 = (400/ 3200) x 100 = 12.5%

There are 5 times as many pens in box A as in box B.
Teddy moves 82 pens
from box A to box B.
Both boxes now have the same number of
pens.
How many pens are in box A now?
Answer:
123 pens in Box A
Step-by-step explanation:
To solve this we will rewrite the word problem as an equation...
5x (A)
x (B)
When Teddy moves 82 pens from A to B, he is subtracting 82 pens from Box A and adding 82 pens to Box B...
5x - 82 (Change in Box A - subtraction)
x + 82 (Change in Box B - addition)
The problem now states that Box A and Box B are equal...
5x - 82 = x + 82
--- subtract x from both sides ---
4x - 82 = 82
--- add 82 to both sides ---
4x = 164
--- divide both sides by 4 ---
x = 41 pens
Now, we replace the x in the expression "5x - 82" with 41...
5(41) - 82 = 205 - 82
205 - 82 = 123
123 pens in Box A

Amakiri spent N125 for a camera and some film. The camera cost N100 more than
the film. What percent of the cost of the two items did Amakiri spend for the camera?
Answer:
90%
Step-by-step explanation:
N125 = 2x + N100
2x = N25
x = N12.5
camera = N100 + N12.5 = 112.5
Total = N125
(Camera/Total) x 100 = % spent on camera
(112.5 / 125) x 100 = 90%
12.) Samuel is 30.75 inches tall. His younger brother, Spencer, is 6 inches shorter. How tall is Spencer?

Suppose a principal amount of $7500 was invested at an interest rate of 6%. How long did it take to reach $10650?
Based on the information how long did it take to reach $10650 is 7years.
Given:
Principal=$7,500
Rate=6%
Amount=$10650
Time=?
Simple Interest(SI)=A-P
=$10650-$7500
=$3150
Time=(100×SI)/(p×r)
T=(100×3150)/(7500×6)
T=315,000/45,000
T=7 years

The period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.
What is the future value?The future value refers to the compounded value of present cash flows in the future, using an interest rate.
The future value can be determined using the future value table or formula.
We can also determine the future value using an online finance calculator, which also enables us to determine the period required to get a stated future value.
Data and Calculations:PV (Present Value) = $7,500
I/Y (Interest per year) = 6%
PMT (Periodic Payment) = $0
FV (Future Value) = $10,650
Results:
N (# of periods) = 6 years
Total Interest = $3,142.17
Thus, the period it took the $7,500 investment to reach a future value of $10,650 at a compounding interest rate of 6% is 6 years.
