Answer:
80%p=d
Step-by-step explanation:
20% discount is 80% of original.
An equation for the relationship between the discount price of an item, d, and it's original price, p is p = 0.8d.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
A store is offering a 20% discount on all items.
Let the discount price of an item, d, and it's original price, p.
The original price = (100 - 20%)discount price
p = 80%d
p = 0.8d
Therefore, p = 0.8d is the required equation.

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°
9514 1404 393
Answer:
73°
Step-by-step explanation:
A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.
-647° +720° = 73°
The least positive measure angle coterminal with A is 73°.
find the height
10cm 8cm
h=
Answer:
h = [tex]\sqrt{84}[/tex] cm
Step-by-step explanation:
The radius, height h and slant height form a right triangle.
radius r = 8 ÷ 2 = 4, hypotenuse = 10
Using Pythagoras' identity in the right triangle
h² + 4² = 10²
h² + 16 = 100 ( subtract 16 from both sides )
h² = 84 ( take the square root of both sides )
h = [tex]\sqrt{84}[/tex] cm
Please help!!
Find the value of x!
Answer:
x = [tex]\frac{16}{3}[/tex]
Step-by-step explanation:
Since the triangles are similar then the corresponding sides are congruent.
EF and BC are corresponding sides , then
8x - 3 = 5x + 13 ( subtract 5x from both sides )
3x - 3 = 13 ( add 3 to both sides )
3x = 16 ( divide both sides by 3 )
x = [tex]\frac{16}{3}[/tex]
A group of friends wants to go to the amusement park. They have no more than $ 100 to spend on parking and admission. Parking is $ 8, and tickets cost $ 23 per person, including tax. Write and solve an inequality which can be used to determine x, the number of people who can go to the amusement park.
Answer:
Step-by-step explanation:
Based on the information given in the question, the inequality which can be used to determine x, the number of people who can go to the amusement park will be:
8 + 23(x) ≤ 100
8 + 23x ≤ 100
23x ≤ 100 - 8
23x ≤ 92
x ≤ 92/23
x ≤ 4
The number of people that can go to the amusement park will be at most 4

Find the length of the line joining the points A(-4.8) and B(-1, 4).
Answer:
5
Step-by-step explanation:
You will need the distance formula.
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
Now you can plug in your 2 points.
A([tex]x_{1}[/tex], [tex]y_{1}[/tex])
B([tex]x_{2}[/tex], [tex]y_{2}[/tex])
[tex]d = \sqrt{(-1 - (-4))^2 + (4-8)^2}[/tex]= 5

Answer:
279 ft²
Step-by-step explanation:
A=bh
A=16x16
A=256
Subtract the area of island
A=bh
A=3x7
A=21
256-21=235
Then you have to find the area of the trapezoid at the top, which is a reactangle and then two smaller triangles
A=bh
A=10x4
A=40
A=1/2bh
A=4x1x1/2
A=2
Multiply it by two because there are 2 of them
2x2=4
40+4=44
The area of the main part is 235 and the area of the side section is 44.
Add them together
235+44=279 ft²
