Answer: There are 30 gallons of anti freeze of first brand and 120 gallons of anti freeze of second brand.
Step-by-step explanation:
Since we have given that
Percentage of anti freeze in first brand = 35%
Percentage of anti freeze in second brand = 85%
Percentage of anti freeze in mixture = 75%
Total number of gallons of mixture = 150 gallons
We will use " Mixture and Allegation":
First brand Second brand
35% 85%
75%
------------------------------------------------------------------
85%-75% : 75%-35%
10 : 40
1 : 4
So, Number of gallons of anti freeze in first brand is given by
Number of gallons of anti freeze in second brand is given by
Hence, there are 30 gallons of anti freeze of first brand and 120 gallons of anti freeze of second brand.

Answer:
If two planes intersect, they intersect in a line. Two planes that do not intersect are called parallel. Given a plane and a line, there are three possibilities. The line and the plane intersect in a single point.

Answer:
13.5
Step-by-step explanation:
It took me awhile, but using the Rational Root Theorem and then synthetic division I got the first root. If you don't know the RRT you'll be in heaps of trouble doing this type of problem. I found the first root to be (x+6), then I did it again and got another root of (x+6) and the third one was (x-5). So the roots of this polynomial (and there are 3 because this is a 3rd degree polynomial) are (x+6) with a multiplicity of 2, and (x-5).
