Answer:
56,000.0
Step-by-step explanation:
The number 6 is in the nearest thousand. To round, you look at the number in front of the number you are trying to round and decide if that number is higher or lower than five. If the number is higher than 5, round up to the next highest number. If the number is lower than 5, the number stays the same.
It is A because the ratio is 2:3
396,000
because 5 goes up and anything lower than five stays the same
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
