The Mattress Depot paid $400 for a bed wholesale, then marked up the price to sell in the store. The retail price is 450% of the wholesale price. At the end of the season, the store will discount the retail price. Which statements are true? Select all that apply.

a. The retail price of the bed in stores is $1800.
b. If the store discounts the retail price of the bed by 30%, the discounted price is $540.
c. If the store discounts the retail price of the bed by 50%, it will make a profit of 125%.
d. The retail price of the bed is $1400 more than the wholesale price.
e. If the store discounts the retail price of the bed by 20%, it will not make a profit.

Answer:

The answer to the question is 540°

Step-by-step explanation:

The reason to the answer is:-

There is a formula which is (n - 2) × 180

n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3

Therefore, 3 × 180 = 540°

The polynomial x^2-18x+81 represents the area(in square feet) of a square courtyard. Write an expression for the perimeter of the courtyard.

Answers

Answer:

4x - 36 feet

Step-by-step explanation:

The area A of a  square whose sides are s units is given as

A = s * s

Given that the area A = x^2-18x+81, factorizing

A = x^2-9x-9x+81

A= x(x-9)-9(x-9)

A = (x-9)(x-9)

A = (x-9)^2

This means that the size of each side of the square  courtyard is x-9 feet long

Recall that the perimeter P of a square whose side is s long is given as

P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard

P = 4(x-9)

= 4x - 36 feet

Answers

Answer:

answer to top question:  x = 3/17

answer to bottom question:  x = -1

Step-by-step explanation:

distribute first

5 + 4x - 6 + 8x = -5x + 2

combine like terms

-1 + 12x = -5x + 2

12x = -5x + 3

17x = 3

x = 3/17

5 - 4x + 6 + 8x = -5x + 2

4x + 11 = -5x + 2

9x + 11 = 2

9x = -9

A steep mountain is inclined 74 degree to the horizontal and rises 3400 ft above the surrounding plain. A cable car is to be installed from a point 970 ft from the base to the top of the mountain. Find the shortest length of cable needed.

Answers

Answer:

3917m

Step-by-step explanation:

We are given that

[tex]\theta=74^{\circ}[/tex]

[tex]h=3400 ft[/tex]

We have to find the shortest length of cable needed.

Let Base=x

We know that

[tex]tan\theta=\frac{Perpendicular\;side}{Base}[/tex]

Using the formula

[tex]tan74^{\circ}=\frac{3400}{x}[/tex]

[tex]x=\frac{3400}{tan74}=975m[/tex]

[tex]y=x+970=975+970=1945m[/tex]

Now, the length of cable needed

=[tex]\sqrt{(3400)^2+(1945)^2}[/tex]

=3917m

Hence, the shortest length of cable needed=3917m

Find the sum 1.56 + 0.083. Show your reasoning

Answers

Answer:

1.643

Step-by-step explanation:

1.56 + 0.083

1.56 = 1.560

Starting from the digits the closest to the right, we do

0.003 + 0.000 = 0.003

0.08 + 0.06 = 0.14

so right now we have 0.143

0.0 + 0.5 = 0.5

so now we have 0.643 (because 0.1 + 0.5 = 0.6)

and finally 1 + 0 = 1

so we end with 1.643

The sum of the expression 1.56 + 0.083 is,

⇒ 1.643

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The expression is,

⇒ 1.56 + 0.083

Now, We can simplify as;

⇒ 1.56 + 0.083

Add as;

⇒ 1.643

Thus, The sum of the expression 1.56 + 0.083 is,

⇒ 1.643

Could someone help with this pls?

Answers

Answer:

61

Step-by-step explanation:

Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.

Simplifying, we get;

9x - 31 + 7x - 2 + 4x + 33 = 180

20x = 180

x = 9.

So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61

Answer: The answer in this photo thanks for a little quiz

The number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

What is an equation?

In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.

Given that, the book they're reading right now is 256 pages long.

Let the number of days be x.

Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.

102+16x -------(i)

Bert has read 142 pages, and he plans to read 11 pages every day.

142+11x -------(ii)

Addison and Bert have each read the same number of pages in total.

So, (i)=(ii)

102+16x=142+11x

16x-11x=142-102

5x=40

x=8

Hence, the number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.
