Hey You!
We must know what 80% of 500 is:
500 * 80% = 400
Ayden did meet is goal, because his goal was 400 and he painted 415 squares (Which is beyond his goal).
Answer:
Step-by-step explanation:
The ratios of the numbers shown in the table are all ...
y/x = 16/4 = 20/5 = 4
Then the missing y-value is ...
y = 4x
y = 4(2) = 8
__
And the missing x-value is ...
36 = 4x
36/4 = x = 9
_____
<em>Additional comment</em>
The x- and y-values in a "ratio table" are proportional to each other. That means the y corresponding to half an x-value will be half the y-value. In other words, the y for x=2 will be half the y for x=4, or 16/2 = 8.
Also, the values add. We notice that y=36 is the sum of y=16 and y=20. This means the corresponding x-value for y=36 will be the sum of x=4 and x=5, or x = 4+5 = 9.

I had the same question I got it right
Slope of line ab = 6-2 / 8-4 = 4/4 = 1
So the slope of the perpendicular line is -1/1 = -1
This line passes through the midpoint of ab
The midpoint of ab = ( 8+4 / 2 , 2+6 / 2) = (6, 4)
Finding the equation of the perpendicular line:-
y - y1 = -1(x - x1) where x1 = 6 and y1 = 4:-
y - 6 = -1(x - 4)
y = -x + 10 is the answer
