B
Here, x is the volume of the 10ml solution. Multiplying it by its concentration gives the amount of alcohol in it. 50 is the total volume of the 12% solution so (50 - x) gives the volume of the 15% solution. Multiplying this by the concentration gives the amount of alcohol in it. The sum of these amounts of alcohols is equivalent to the amount of alcohol in the 12% solution which is given by the product of its volume and concentration.

The equation of the line into point slope form is equal to
In this problem we have
substitute the given values

therefore
y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)
Answer:
The profit margin for the concert sponsorship is 31.3725 %
Step-by-step explanation:
An arena receives for 1 event = $1700
An arena receives for 12 events = 
An arena receives for 12 events = 20400
The costs for this sponsorship total $14,000
Profit = 20400-14000
Profit =6400
Profit margin =
Profit margin = 
Hence the profit margin for the concert sponsorship is 31.3725 %
The height you are looking for is called the "slant height".
slant height^2 = height^2 + (half the base length)^2
slant height^2 = 62^2 + 31^2
slant height^2 = 3,844 + 961
slant height^2 = 4,805
slant height =
