Answer:
d^2 = 12^2 + 5^2 = 169
d = 13
r = d/2 = 6.5
A = pi·6.5^2 = 132.73 cm²
Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.
Answer:

Answer:
$642
Step-by-step explanation:
To calculate sales tax, you multiply the percentage by the price. In this case it would be 600 x 0.07 which is 42. Then you add them together which would be 600 plus 42 which equals 642.
V = lhr
V ÷ lh = lhr ÷ lh
V/lh = r
r = V/lh
Just divide both sides by what you want removed, leaving behind r.
