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).
Assuming the equation is 3x-2y+4=0 then the equation of the line, solving for y in terms of x, gives y=3/2x+2 the slope of this line is 3/2 then the slope of a line that is perpendicular is -2/3 .An easy way to see this is to draw the line. By definition the slope, m=tan(α) where α is the angle the line makes with the x axis. Let L=slope of the perpendicular line then L=tan(β) but the two lines with the x axis form a right triangle hence α+π-β=π/2 so β=π/2+α and L=tan(β)=tan(π/2+α)=-cot(α) = -1/tan(α)=-1/m.In our problem m=3/2 so L=-2/3.The geometry becomes clear if you make a sketch of the two lines. Hope this helps
Hi!
240*.75 = 180
180*.9 = 162
$162
Hope this helps!
Answer: 11 hours
Step-by-step explanation:
First, you divide 495 by 45
and you get 11
to double check you can just multiply 11 by 45 and you'll get 495
(i think thats how you do it)
