Step-by-step explanation:
2 because for every 5 she gets she gives 2 to her brother and she only got one 5 so its 2
The pH of distilled water is usually LESS THAN 7, because when it contacts air CO2 gas begins dissolving into the water.
The answer would be 40.
to answer this, u can use the is over of equals to % over hundred.
is %
__ = ___
of 100
the is would be 24 and the percent would be 60.
so,
24 60
__ = ___
x 100
to answer this u would cross multiply.
24x100=2400
60x X=60x
then, divide
6\0x 2400
__\___ = _____
6\0 60
2400 divided by 60 is 40.
40 is the answer.
A.) Revenue = price * quantity = px = -1/20x^2 + 1060x
R(x) = -1/20x^2 + 1060x.
b.) Profit = Revenue - Cost = R(x) - C(x) = -1/20x^2 + 1060x - 120x - 5000
P(x) = -1/20x^2 + 940x - 5000
c.) For maximum profit, dP/dx = 0
-1/10x + 940 = 0
1/10x = 940
x = 940 * 10 = 9,400
x = 9,400
Maximum profit = P(9400) = -1/20(9400)^2 + 940(9400) - 5000 = $4,413,000
d.) The price to be charged for maximum profit = -1/20(9400) + 1060 = $590
