Answer: 181.25
Step-by-step explanation:
So 4 to 5 is a ratio. Now there is 145 girls, so you figure out 4 multiplied by what is equal to 145. You get 36.25, so you multiply the number 5 by the same number to get your answer. 36.25*5=181.25
Answer:
C. The graph of the function starts high and ends low
Step-by-step explanation:
For
, as
approaches negative infinity,
approaches infinity, and as
approaches infinity,
approaches negative infinity.
Thus, we have:

This corresponds with answer choice C. The graph of the function starts high and ends low.
The unit cost of the fencing and the cost of a bag of mulch together with
the area and perimeter of the garden give a cost sum of $36.5.
Response:
- The amount required to spend is <u>$36.5</u>
<h3>How does the unit cost determine the total cost?</h3>
Cost of the barrier per feet (unit cost) = $0.75
Area covered by one bag of mulch = 7 square feet
Cost of one bag of mulch (unit cost) = $5
From the given diagram, we have;
Area of the garden = 8 ft. × 2 ft. + 0.5 × 8 ft. × 3 ft. = 28 ft.²

Length of fencing = 2 ft. + 8 ft. + 2 ft. + 5 ft. 5 ft. = 22 ft.
- Amount to spend = 4 bags × $5 + 22 ft. × $0.75 =<u> $36.5</u>
