Answers
Answer:
2x+15=33
Step-by-step explanation:
Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.
Since he started doing 15 sit-ups on the first day, the total number of sit-ups
after x days would be 2n+15.
Since he did a total of 33 sit ups today, then 2n+15=33

Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150
Answers
So 1150 (measured by the experiment) - 1081 (the estimate = theory)/1081 = 69/1081 = 0.0638 x 100 = 6.38%
The percentage error in the situation, where Estimated value 1081
and Actual value 1150 is, 6%
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
Estimated value: 1081
Actual value: 1150
Percentage error = [Actual value - Estimated value]/Actual value×100
= [1150 - 1081]/1150×100
= 6
Hence, the percentage error is 6%

A teacher asks four students to determine the area of a circle with a circumference of 50.24 feet. The table shows the students’ responses.
Which student determines the area of the circle correctly? (Use 3.14 as an approximation of pi.)
Answers
Student 3 determines the area of the circle correctly.
What are the circumference and diameter of a circle?The circumference of a circle is the distance around the circle which is 2πr.
The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.
Given, A circle has a circumference of 50.24 feet.
We know the circumference of a circle is 2πr.
Therefore, 2πr = 50.24.
πr = 50.24/2.
πr = 25.12.
r = 25.12/3.14.
r = 8 feet.
We also know the area of a circle is πr².
= π(8)² square feet.
= 200.96 square feet.
Student 3 determines the area correctly.
