Answer:
Dan is correct
Step-by-step explanation:
First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.
Answer:
7x(3-5a)
Step-by-step explanation:
21-35a =
to find a minimum common multiply you have to rationalize the number with the same numer, and this number must be a whole, this will help you to write the expression easier, if you notice that 21 and 35 are familiar of 7, then you can find a common factor, to multiply your expression

Answer:
- 65.312 inches
- 326.56 inches
- 1959.36 inches
Step-by-step explanation:
<h3>Given</h3>
<h3>To find</h3>
- Travel in 1, 5, 30 rotations
<h3>Solution</h3>
<u>Circumference of the wheel is equal to one full rotation</u>
- C = πd = 3.14*20.8 = 65.312 inches
- 5C = 5*65.312 = 326.56 inches
- 30C = 30*65.312 = 1959.36 inches
