Answers

Answer:

To find a power of a product, find the power of each factor and then multiply. In general, (ab)m=am⋅bm. am⋅bm=(ab)m. In other words, you can keep the exponent the same and multiply the bases.

Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150

Answers

You take (experimental value - theoretical value), over/divided by theoretical value. Then multiply by 100 to get the percentage.

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%

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Please show all work.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers


You meed to subtract and divide

Answer:

the circumference is 5, since the diameter is half, so you have to double 2.5 to get 5.    2.5 + 2.5 = 5

if the tire rotates 1 time and gains 5 feet, we have to divide 5 from 5,280. So...

5,280 ÷ 5 = 1056

it rotates 1056 times to get to 1 mile!

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.
