To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)
50*.86=43 people
Hope this helps
This is a quadratic equation, i.e. an equation involving a polynomial of degree 2. To solve them, you must rearrange them first, so that all terms are on the same side, so we get

i.e. now we're looking for the roots of the polynomial. To find them, we can use the following formula:

where
is a compact way to indicate both solutions
and
, while
are the coefficients of the quadratic equation, i.e. we consider the polynomial
.
So, in your case, we have 
Plug those values into the formula to get

So, the two solutions are


Answer:
y=-1
From where the line crosses the y axis, it goes up 1 and over 1 from each plane although its moving to the left from 0 every time. This means the slope is negative.
In the equation y=mx+b, b is the y intercept and m is the slope
plugin the info and you get y=-1x+0 or
y=-1x
Step-by-step explanation:
Solution:
we are given that
In the image, shape ABCD is similar to shape WXYZ.
we have been asked to find the measure of side ZW.
As we know that when two shapes are similar then the ratios of their corresponding sides are equal.
So we can write

Hence ZW=4.5 Inches.
Answer:

Step-by-step explanation:

Subtract 2 from both sides:


Subtract 5x from both sides:


Divide both sides by 2:
