Kylie saved $550 from babysitting. she used 32% of her money for a down payment on summer camp and 3/20 of her savings for two new video games. she deposited the rest into a college savings account. expressed as a decimal, what part of her money did kylie deposit into her college savings account?

%53

Step-by-step explanation:

3/20=%15

15+32=%47 for both video games and camp

100-47= %53 left over for college

.53

Step-by-step explanation: Of Kylies $550, 32% was for a down payment for summer camp. This is calculated with the formula 550 x .32 = $176 down payment.

She used 3/20 for two video games. 3/20 = .15, so the video games cost .15 x $550 = $82.50.

Kylie spent $176 + $82.50 = $258.50.

$550 savings - $258.50 = $291.50 is the amount that she put into her savings account. Expressed as as decimal, it is 291.50/550 = .53, so she put .53 of her babysitting money into her college savings account.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

what i would say the best answer is a. 40.5
