A tv that usually sells for $189.91 is on sale for 20% off. If sales tax on the tv is 6%, what is the price of the tv, including tax?

$161.04

Step-by-step explanation:

189.91 * .20 = 37.98 (to determine amount off)

189.91 - 37.98 = 151.928 (sale price)

151.928 * .06 = 9.116 (amount of tax)

total 151.928 + 9.116 = 161.044 rounded to 161.04

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

-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
