If 26 problems are 65%, then you can figure out the number of all of the problems.
26/x=65/100
65x=2600
x=40
If there are 40 total problems and Frank has done 26, he needs to complete 14 more.
Answer:
Rational numbers can be written as a fraction where p and q are integers and q is not equal to zero
we know that
the equation
describe a vertical parabola with vertex at point
if -------> the parabola open Up and the vertex is a minimum
if -------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
25 degrees it shows on the protractor
