Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.

Answer:
10,000
Step-by-step explanation:
In order to round numbers we look at the number to the right of whatever we are rounding to. So in this case we are rounding to the nearest thousand so we look at the number to the right of the thousands which is the hundred in this case. If that number is a 1-4 we round down and if that number is a 5-9 we round up. In this case the number to the right is a 9 so we will round up. The nearest thousand above 9991 is 10,000 so that is what we will round to
