Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his incline skates 32 cm in circumference. How many rotations does each wheel make while Shawn is coasting down the ramp. Round your answer to the nearest rotation.

Step-by-step explanation:

16 rotations

500/32 = 15.625

15.625 rounded = 16

Therefore, the answer is 16 rotations.

Why:

500 and 32 are both given to you in distance. By divided 500 by 32 will give you how many times the shorter distance can fit into the longer distance. This will then give you the amount of rotations in the greater distance.

Once you have the answer, it asks for you to round to the nearest rotation. 15.625 rounds to 16 because 6 is in the tenths place. And we all know a number 5 or greater rounds up. So, 16 is the correct answer.

It should be 16 rotations

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
