Answer:
There are 14 dimes and 17 nickels.
Step-by-step explanation:
Let x be number of nickels and let y be number of dimes.
Given that the total is $2.25 and there are 31 coins, we know that:


Solving for x yields:

We then proceed by plugging that back into the previous equation:

--> Distribute
--> add y's together
--> subtract 1.55
--> divide by 0.05
Therefore, x must equal 17, which means you have 14 dimes and 17 nickels.

Answer:
d) 100 feet
Step-by-step explanation:
The x value of the vertex (highest point in this case) is found via -b/2a:
-80/-32 = 2.5
Plug 2.5 into the function:
h(2.5) = -16(2.5)² + 80(2.5)
= - 100 + 200 = 100
