The answer is 20%
[(150 - 125) / 125] × 100% = 0.2 × 100% = 20%
hope that i have helped!
185% = 185/100
185/100 = 37/20
The simplest form fraction of 185% is 37/20.
You actually have to do the break our rooms to find the code wish i could help
N=-5, you must isolate your variable(n), so divde 4 by -0.8, which equals -5.
The first line equation: y = -2/7x - 5; m1 = -7/2
The second line passes through (2,4) and is perpendicular to the first line.
Therefore,
The gradient of first line = -1/m1 = -1/(-2/7) = 7/2
Then, the equation of the second line is;
y = 7/2x+b
Substituting for the coordinates given;
4 = 7/2(2)+b
4 = 7+b
b = 4-7 = -3
Therefore, the equation of the second line is;
y = 7/2x - 3
In standard form, the equation this equation can be written as:
y(2) = 7x - 3(2)
2y = 7x - 6
7x -2y - 6 = 0 -----> standard form.
