Answer:
The tip was 30% percent
Step-by-step explanation:
All you have to do is the following, total price difference/ original price. 4.20/14 is 0.3, so 30 percent.
Answer:
or 
Step-by-step explanation:
One is given the following equation:

The problem asks one to simplify the expression, the first step in solving this equation is to factor the equation. Rewrite the numerator and denominator of the fraction as the product of two expressions. Remember the factoring patterns:



Now simplify the numerator. Remember, taking the square root of a squared value is the same as taking the absolute value of the expression,


Rewrite the expression without the absolute value sign in the numerator. Remember the general rule for removing the absolute value sign:
or 

or 
Simplify both expressions, reduce by canceling out common terms in both the numerator and the denominator,
or 
or 
Simplify further by rewriting the expression without the parenthesis, remember to distribute the sign outside the parenthesis by the terms inside of the parenthesis; note that negative times negative equals positive.

Zinger 1 = -16(6)^2 +150(6) = 324 feet
Zinger 2 = -16(6)^2 + 165(6) = 414 feet
414-324 = 90 feet
Zinger 2 is 90 feet higher
It would be B, Mode and Median!!
I don't even actually need to work this one out. The rule between the volumes of a cylinder and a cone is that is they have the same height and diameter, the the volume of the cone is one-third that of the cylinder. But in this case the cone's height is three times that of the cylinder. So I predict that their volumes are the exact same. But working it out, the volume of a cylinder is V=πr2h, and plugging in all the appropriate values the volume of the cylinder is 251.33 square inches. And the volume of a cone is V=πr2(h/3), and plugging in the values given to me here the volume of the cone is 251.33 square inches. Therefore their volume is the same.
