To turn a percent into a decimal, move the decimal point over to the left two places.
For example, 25% would be .25 as a decimal.
An easy way to remember how many places the decimal point moves is by looking at the percent sign. It has two circles on either side of the slash, so two circles = two places.
The prime factors of 700 = 2 x 2 x 5 x 5 x 7.
Answer:
X=2
If you substitute 2 in for x, you get 35 for both angles. Since both sides are the same, the answer has to be 2.
So there are 26 letters in the alphabet and 4 symbols here. If you calculate 4 out of 26, that would equal 15.38% or 0.15.
If John charge $12 then he has 14 students, and he gets $ 14*12,
If he increases on $2(12+2) , he loses 1 student (14-1), gets (12+2)*(14-1)
if he increases on he loses 2 students (14-2) gets (12+2*2)(14-2)
2+2 (12+2*2)
if he increases 2*3 he loses 3 students, (14-3) gets (12+2*3)(14-3)
2x*3 (12+2*3)
and so on......
if he increases 2*x, he loses x students, (14-x)left, gets (12+2x)(14-x)
(12+2x)
So , his revenue in general =
(12+2x)(14-x)=12*14-12x+28x-2x²=-2x²+16x+168
<em> I think it should look like this
</em>c(x)= -2x²+16x+168
