Answer:
uhh i think 175
Step-by-step explanation:
The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.
First, measure the diameter of the tire in inches.
Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62 inches.
Hope this helped
Step-by-step explanation:
Here is the answer to this question,
His hypothesis would be:
Null hypothesis:
H0: μ(new) - μ(regular) = 0
Alternate hypothesis:
H1: μ(new) - μ(regular) > 0
The consumer is testing to know if his new detergent is better off in cleaning than the regular. The question says that higher scores after cleaning is used to signify which is better based on sufficiently clean garment. Since he is interested in knowing the mean scores of the differences, he should use the hypothesis I stated above.
Answer:
Step-by-step explanation:
The given circle has circumference 136cm.
The formula for circumference is 
This implies that:
The area of a circle is given as 
When 
Answer:
42p + 21r
Step-by-step explanation:
First look at the parentheses. Since 4p and 2p are the same variables, you can add them.
7(6p + 3r)
now you use the distributive property.
7 x 6p + 7 x 3r
42p + 21r
and then you get you’re answer.
