Answer:
B and D
Step-by-step explanation:
a is right because there are numbers that exist that are larger than five and smaller than 9
c is right because again, there are numbers that exist that are larger than -3 and smaller than 7.
b cannot be right because there are no numbers that can be larger than 9 that are also smaller than 5
d also cannot be right because there are no numbers that are less than -5 that are also more than -3.
Answer:
16 acres
Step-by-step explanation:
First find the operating cost for 1 acre. Find that by dividing $551,520 by 20 acres. That gives us $27,576 per acre. Now we can set up a proportion to solve for the number of acres that have an operating cost of $441,216:

Cross multiply to get:
27576x = 441216 so
x = 16
We did not have to find the cost per acre to solve this. We could have set up the proportion with $551,520 on the top of the ratio and 20 on the bottom and we would still have gotten the same answer. I just figured the numbers wouldn't be as large if we divided to find the cost per unit.
