60 more students voted for Kevin
Step-by-step explanation:
Given
total students = 300
Voted for Jennifer = 40%
Voted for Kevin = 60%
We will find number of students for one of them and then will subtract from total to find the others.
So,
Students who voted for Jennifer:
Students who voted for Kevin
=
In order to calculate that how many more students voted for Kevin :
180-120 = 60
Hence,
60 more students voted for Kevin

First step is to factor. With a polynomial function in the form ax² + bx + c = f(x), we have to find what factors of term C have a sum of term B.
So with this, we need factors of -90 add up to become -1. Your factors are - 10 and 9.
f(x) = x² + 9x - 10x - 90
Now we group together and pull out GCFs.
f(x) = (x² + 9x) + (10x - 90)
f(x) = x(x² + 9) - 10(x + 9)
f(x) = (x - 10)(x + 9)
Now, set each factor equal to zero.
x - 10 = 0, x + 9 = 0
For the first equation you are going to add 10 to both sides to get x by itself. Subtract 9 from both sides in the second equation for the same reason.
x = 10, x = -9
Your zeros are at x = -9, 10 or at the ordered pairs (-9, 0) and (10, 0).

Answer:
8.1 * 10^-2
Step-by-step explanation:
Scientific notation is a number with it's largest digit in the one's place and its succeeding digits following it as decimals, then multiplied by a power of ten.
Appling this knowledge to the given number, we can conclude:
0.0810
= 0.081
= 8.1 * (1/10) * (1/10)
= 8.1 * 10^-1 * 10^-1
=9.1 * 10^-2
