Find the discount price and subtract from the total to find the sale price.

To find the discount price, multiply 90 b 40% (convert 40% into decimal)

90 x 0.4 = 36

Next, subtract the discount from the total to find the sale price.

90 - 36 =  54

So, the sale price is <u>$54</u>.

Find the area of the figure.
jek_recluse [69]

Answer:

The answer is 100 inches. (Please read how I got my answer)

It is 100 inches, because you need to find the whole area inside each figure, inside the actual entire figure, not the figures inside of the figure. Which would mean, 2in and 2in would be 4in, 2in and 3in would be 6in and 2in and  5in, would be 10 in. You can then multiply them all together. That would be 100.

To get this, you divide the smaller number by the larger one and get 0.5882... 500 is about 59% of 850, so to find the percent lost, you subtract that from 100 to get 41% decrease

Write the equation of the line that passes through (2,5) and is perpendicular to Y=(1/2)X-1
V125BC [204]
We know that
if two lines are perpendicular
then
m1*m2=-1
where
m1 and m2 are the slopes of the lines

step 1
For <span>Y=(1/2)X-1
</span>slope m1=(1/2)
so
m2=-1/m1-----------> m2=-1/(1/2)-------> m2=-2

step 2
with m=-2 and the point <span>(2,5)  find the equation of the line
y-y1=m*(x-x1)------> y-5=-2*(x-2)-----> y=-2x+4+5------> y=-2x+9

the answer is
y=-2x+9
see the attached figure
