Call the production cost 'C', the revenue 'R' and the number of CDs 'n':
C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.
Answer:
(-1,-1) and (4.1).
1+1
slope of the line: m= ------- = 2/5
4+1
the slope of the perpendicular line: -5/2 and point (-1,3)
(y-3) = -5/2(x+1)
Answer:
The volume of the cone is 42.6 m^3
Step-by-step explanation:
The volume of a cone is given by the area of the base multiplied by the height of the cone and divided by three. The base is a circle, so it's area is computed by the following:
Abase = pi(r^2) = 3.14(2.2^2) = 15.2 m^2
We can then compute the volume of the cone that is:
Vcone = Abase*h/3 = 15.2*8.4/3 = 42.56 m^3
The volume of the cone is 42.6 m^3
Answer:
9:50
Step-by-step explanation:
To get the ratio, we can just simplify a fraction down to 1.
Since there's 18 dimes, and 100 coins in total, we'll start with the fraction
18/100
Put 18/100 in simplest form
9/50
Then Turn the fraction into a ratio
9/50 -> 9:50
For every 9 dimes there's 50 coins.
I hope this helped.
(Simplified to 1, is 1/5.56 or 1:5.56)
