Answer:

Step-by-step explanation:

In order to solve this question, we need to subtract the smaller area of the hole from the bigger area of the actual donut. We use the formula $a=\pi r^2$ . We plug the numbers in for the smaller circle and the area of the smaller circle is 3.14. Then, we plug in the numbers for the bigger number and we get 28.27. We subtract 3.14 from 28.27 and we get approximately 25, which is equal to J.

Answer:

% error = 3.3%

Step-by-step explanation:

Percent Error Formula:

% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100

% error = ( (12.7 - 12.3) / 12.3 ) * 100

% error = (0.4/12.3) * 100

% error = (0.03252033) * 100

% error = 3.25203252

% error = 3.3%

A teacher has a box of pens and pencils. There are 8 more pencils than pens. After the students take 1 pen and 5 pencils from th

crimeas [40]

Let no. of pens be x.

Pens : x
Pencils: x+8

Total: 2x+8

Student takes 1 pen and 5 pencils.

Remainder: 2x+8 - 5 -1 = 2x+2
2x+2 = 26
2x= 24
x = 12 (original no. of pens)
x+ 8 = 20 (original no of pencils)

There are 12 pens at first and 20 pencils.
After 1 pen is taken, 11 pens are left.
After 5 pencils are taken, 20-5=15 pencils are left.
