Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
Answer:
Step-by-step explanation:
Answer:
the answer is A or F (both are the same answer which is 40)
48÷8=6
6×20=120
so 20 plates cost 120 dollars
A percentage is really just a decimal with the point moved over
a couple of places. So what you really need is just the decimal
form of 36/48.
As always, a fraction is just a short way to say "divided by", and
when you actually go ahead and do the division indicated by the
fraction, you get the decimal.
When you divide 36 by 48, the quotient is 0.75 .
To turn a decimal into a percentage, move the point 2 places
toward the right.
0.75 = 75%
