Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.
Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:
<em>Circle area formula: </em>πr²
<em>Radius:</em> 12/2 = 6ft
<em>Our case:</em>
(π * 6²)/2 =
36π/2 =
18π = 56.55ft²
The easiest way to find a percentage is to divide the two numbers. You're trying to find what percent 3,000 is of 25,000, so you divide 3,000 by 25,000 to find the decimal.
3000/25,000 = 0.12
If you move the decimal point to the right two places, you'll have your percentage. (Percent means "out of one hundred", and since the decimal point is now in what was the hundredths place, it is now a percentage instead of a decimal.)
12%
$3,000 is a 12% raise from $25,000.
The answer to your problem is: 122.32
The answer is C because 3/4 is the biggest of them all and the only one saying that is C.
