a computer costs 400 dollars. Its 20 percent off with an additional 5 percent off, there's no sales tax. How much does the compu

zhenek [66]

The computer costs $304 now.

Step-by-step explanation:

Given,

Cost of computer = $400

First discount = 20%

Amount of discount = 20% of $400

Amount of discount = $\frac{20}{100}*400=\frac{8000}{100}$

Amount of discount = $80

Price after first discount = 400-80 = $320

Additional discount = 5%

Amount of additional discount = 5% of price after first discount

Amount of additional discount = $\frac{5}{100}*320=\frac{1600}{100}$

Amount of additional discount = $16

Final cost = 320-16 = $304

The computer costs $304 now.

G(-2, 5), H(6, 5), J(6, -1)<br> 17. Find the coordinates of the centroid.

adell [148]

The coordinates of centroid are: (10/3, 3)

Step-by-step explanation:

The formula for calculating centroid of a triangle is:

$(x,y) = (\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})$

Here (x1,y1) are the coordinates of first vertex

(x2,y2) are the coordinates of second vertex

(x3,y3) are the coordinates of third vertex

Given:

G(-2,5) = (x1,y1)

H(6,5) =(x2,y2)

J(6,-1) = (x3,y3)

Let I be the centroid of the triangle

Putting the values in the formula

$I(x,y) = (\frac{-2+6+6}{3},\frac{5+5+-1}{3})\\= (\frac{10}{3},\frac{9}{3})\\=(\frac{10}{3},3)$

The coordinates of centroid are: (10/3, 3)
