Answer:
78
Step-by-step explanation:
You take the original total: 60, and multiply it by 30 to get 1,800. You then divide 1,800 by 100 to get 18. 18 is your 30%. Now, you add the 30% to 60 getting your total number of ducks: 78.
The equation version:

It is just proportions.
Instantaneous rate of change = S'(r) = 8πr
S'(8) = 8π(8) = 64π
Therefore, the instantaneoud rate of change of the <span>surface area with respect to the radius r at r = 8</span> is 64π

Answer:
2
Step-by-step explanation:
If p = 5 and q = 1, the equation would look like
2 - (1 - 5/5)
2 - (1 - 1) [5/5 is a giant 1]
2 - (0)
2
41.00
25% off $45 is 33.75
You then add 7.25 to 33.75 which is $41
