krek1111 [17]
This is the working of how it is 28% discount

Find the amount of discount : $125 - $90 = $35
Divide by the original price : $35/125 = 0.28
Change in to percentage : 0.28 x 100 = 28%

Therefore the percentage discount is 28% off

(-4,5) and (4,0) find the distance between each pair of points
aleksklad [387]

Answer:

9.4339 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) = (-4,5)

(x_2,y_2) = (4,0)

Replacing these values in the distance formula

D =\sqrt{(-4-4))^2+(5-0)^2}

D =\sqrt{(-8)^2+(5)^2}

D =\sqrt{64+25}

D =\sqrt{89}

D= 9.4339

Hence the distance is 9.4339 units

Two angles are complementary. one of the angles is twice the other.the larger angle has a measure of
horrorfan [7]
Complimentary angles will add up to 90 degrees

x + y = 90
x = 2y

2y + y = 90
3y = 90
y = 90/3
y = 30......this is one angle

x = 2y
x = 2(30)
x = 60.....this is ur other angle

and ur larger angle is 60 degrees
