Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.
If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.
After that just check your answer by seeing if the mean of all the numbers is the same.
Answer:
$74.97
Step-by-step explanation:
Cost of skateboard = $79.43
Less 12 % = 0.12 × 79.43 = <u> -9.53
</u>
Sale price = 69.90
Plus sales tax = 0.0725 × 69.90 = <u> +5.07
</u>
Total cost = $74.97
