Answer:

$427,500 dollars

Step-by-step explanation:

Given the following question:
Initial price = 450,000
5% discount

In order to find the answer, we simply find 5% of 450,000.

\frac{5\times450000}{100} =5\times450000=2250000\div100=22500
450000-22500=427500
r=427500

The radio (after a 5% discount) costs "$427,500 dollars."

Hope this helps.

The angles in a triangle are such that one angle is 120 degrees more than the smallest angle, while the third angle is 3 times a
fomenos

Answer:

The measures of the angles are

132\°, 12\° and 36\°

Step-by-step explanation:

Let

x-----> one angle

y----> the smallest angle

z----> the third angle

we know that

x+y+z=180\° -----> equation A

x=120\°+y ----> equation B

z=3y -----> equation C

substitute equation B and equation C in equation A and solve for y

(120\°+y)+y+3y=180\°

5y+120\°=180\°

5y=180\°-120\°

y=60\°/5=12\°

<em>Find the measure of x</em>

x=120\°+12\°=132\°

<em>Find the measure of z</em>

z=3(12\°)=36\°

therefore

The measures of the angles are 132\°, 12\° and 36\°

What is the equation of the line that passes through the points (-7,-7) and (-7,4)
musickatia [10]

Answer:

Step-by-step explanation:

The equation of a line

y = mx + c

y - intercept point y

m - slope of the line

x - intercept point x.

c - intercept of the line

Step 1: find the slope

m = y2 - y1 / x2 - x1

Given two points

( -7 , -7) ( -7 , 4)

x1 = -7

y1 = -7

x2 = -7

y2 = 4

Insert the values into the equation

m = 4 - (-7) / -7 -(-7)

m = 4 + 7 / -7 + 7

m = 11/ 0

Step 2: sub any of the two points given into the equation

y= mx + c

y = 11/0x + c

(-7 ,4 )

x = -7

y = 4

4 = 11/0(-7) + c

4 = -77/0 +c

-77/0 is math error which means that the points are not correct
