I know that 20% is out of 100.If I changed this problem to be a fraction problem,I would change that percent to 20/100.55 would be the denominater of the other fraction.Right now we're trying to find the numerator for the denominator of 55 to make this a complete fraction.Secondly,I would try to find a common denominator to get my answer.I'm going to make the common denominator......5500.As my teacher always said what you do to the bottom you do to the top and it goes the other way around too.So, i will times 20*55 to get my numerator.This equals 1100.Now I would divide this fraction by 100 to get my finished answer.The answer is 11 is 20% of 50.
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)
For lines to be parallel, they have to have the SAME slope.
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -2/3
perpendicular line's slope is 3/2
9.) First find the slope of line PQ. Use the slope formula and plug in the two points.
P = (4, 1) (x₁ , y₁)
Q = (8, 4) (x₂ , y₂)



Line RS is parallel to line PQ, so they have the same slope of 3/4

To find "b", plug in the point R = (3, -2) into the equation


Subtract 9/4 on both sides
Make the denominators the same



10.) Find the slope of line PQ


Line RS is perpendicular to line PQ, so the slope of line RS is -4/3
y = -4/3x + b
Plug in the point R = (3, -2) into the equation to find "b"
y = -4/3x + b
-2 = -4/3(3) + b
-2 = -4 + b Add 4 on both sides
2 = b

The cube root of 512 is 8.
I hope this helps you.
Photosynthesis is how plants turn energy from the sun into glucose (which is energy for the plant to use)
