Answer:
The original price was $90.
Step-by-step explanation:
Let j represent the original price. Then, subtract 20% from 100%, obtaining 80%. The markdown price is 80% of j, or 0.80j = $72
Solving for j, we get j = $72/0.80 = $90
Answer:
86.40
Step-by-step explanation:
86.4 rand 72 plus 14.4 equals 86.40

Answer:
3x-x+2=4
Step-by-step explanation:
What is the equation of the line that is perpendicular to y=1/5x+4 and that passes through (5,—4)?
=========================================================
Work Shown:
The given equation y = (1/5)x+4 is in the form y = mx+b with m = 1/5 as the slope.
Apply the negative reciprocal to this slope to go from 1/5 to -5/1 or -5.
The original slope is 1/5 and the perpendicular slope is -5. Note the two slopes multiply to -1. This applies to any pair of perpendicular lines as long as neither line is vertical.
---------
We'll use m = -5 as the slope and (x,y) = (5,-4) to find the y intercept
y = mx+b
-4 = -5*5+b
-4 = -25+b
-4+25 = b
21 = b
b = 21
The y intercept of the perpendicular line is b = 21
With m = -5 and b = 21, we go from y = mx+b to y = -5x+21 which is the equation of the perpendicular line.

Triangles S T U and W V X are congruent. Angles W and W are congruent, T and V are congruent, and U and X are congruent. Which of the following statements are correct based on the diagram? Select all that apply. Segment U T is congruent to segment X V Angle S is congruent to angle V Segment S T is congruent to segment W V Angle V is congruent to angle T Segment U S is congruent to segment X V
The correct option will be that S T is congruent to segment W V.
Congruent trianglesGiven the triangles STU and WVX, if the triangje are congruent, then the measure of their sides will be the same.
Since the corresponding angles are congruent, hence the equivalent sides will be:
ST = WV
Su = WX
TU = VX

Answer:
15. d) 36
16. b) 20
17. d) 180
18. b) 50
19. c) 360
20. b) 60
Step-by-step explanation:
To find the number of sides a polygon has giving an interior angle, use the equation:
(number of sides - 2)*180/(number of sides) = measure of interior angle
15. (n = number of sides)
((n-2)*180)/n = 170
180n-360 = 170n
10n = 360
n = 36 (d)
16. (n = number of sides)
((n-2)*180)/n = 162
180n-360 = 162n
18n = 360
n = 20 (b)
17. The sum of the interior angles of a triangle is always 180 (d)
18. 180-60-70 = 50 (b)
19. The sum of the interior angles of a quadrilateral is always 360 (c)

The school cafeteria buys bottles of water for $0.75 each and sells them for $1.05 each. By what percentage does the cafeteria markup the price of water bottles? Do NOT include units or percent signs!
Answer:
40
Step-by-step explanation:
Cost of the bottles of water = $0.75
Sales of the bottle= $1.05
markup Price= [(Sales of the bottle)-(Cost of the bottles of water)]/Cost of the bottles of water
= ($1.05- $0.75)/$0.75
= $0.30/$0.75
=0.40×100%

The last time I posted this question some random person took the points so DONT DO IT AGAIN (YOU KNOW WHO YOU ARE)Write the equation of a line in slope-intercept form with a slope of 10 and passes through (–4, – 25).
Answer:
[tex]y=10x+15[/tex]
Step-by-step explanation:
We want the equation of a line with a slope of 10 and passes through (-4, -25).
We can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, we will substitute 10 for m and (-4, -25) for (x₁, y₁):
[tex]\displaystyle y-(-25)=10(x-(-4))[/tex]
Simplify:
[tex]y+25=10(x+4)[/tex]
Distribute:
[tex]y+25=10x+40[/tex]
Subtract 25 from both sides:
[tex]y=10x+15[/tex]
And we have our equation.
What are the ratios for SIN A and COS A
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=Opposite over Hypotenuse
Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].

Answer:
1. d ≈ 19
2. a ≈ 39.00°
3. x ≈ 37°
Step-by-step explanation:
1) Using sine to find d, recall that sine = opposite side/hypotenuse. So:
[tex]sin(39) = \frac{d}{30}[/tex]
Cross multiply:
d = 30 (sin(39))
d ≈ 19
2) To find the measure of the angle, we can use sine because we have the opposite side and hypotenuse measures. So:
[tex]sin(a) = \frac{18.88}{30}[/tex]
Using the inverse of sine:
[tex]a = sin-1(\frac{18.88}{30})[/tex]
Input into calculator:
a ≈ 39.00°
3) To find the measure of the angle, we can use tangent because we have the opposite side and adjacent side measures. So:
[tex]tan(x) = \frac{300}{400}[/tex]
Using inverse of tangent:
[tex]x = tan-1 (\frac{300}{400})[/tex]
Input into calculator:
x ≈ 37°
