A furniture store owner buys a sofa for $400 and marks it up %90 to sell it. During the stores anniversary sale she sells the sofa for %25 off. How much profit will the store owner make on the sofa during the anniversary sale?

Answers

Answer:

Anniversary sale price= $570

Step-by-step explanation:

Giving the following information:

Purchase cost= $400

Mar-up percentage= 90%

First, we need to calculate the "normal" selling price:

Selling price= 400*1.9= $760

Now, we can determine the anniversary sale price:

Anniversary sale price= 760 - (760*0.25)= $570

Angle 4 = 104 degrees Angle 6 = (2x - 4) degrees Solve for x.

Answers

Answer: x = 40

Step-by-step explanation:

104 + 2x -4 = 180

104 - 4 + 2x = 180

100 + 2x = 180

2x = 180 -100

2x = 80

x = 80/2

x = 40

8. Sheila buys two concert tickets from her friend.
She pays $90 for the two tickets. She looks at the
tickets and sees that each ticket has a face value
of $52.50.

B.What was the percent markdown, rounded to the nearest whole percent

Answers

Cost of two tickets that Sheila paid to her friend = $ 90

Actual price of 1 ticket = $ 52.50

So, actual price of 2 tickets = 52 x 2 = 105

Hence, markdown or discount Sheila's friend gave her is =

105 - 90 = 15

The answer is $15.

Answer:

Step-by-step explanation:

105 - 90 = 15

A side of the triangle below has been extended to form an exterior angle of 156°. Find
the value of x

Answers

Answer:

x=24

Step-by-step explanation:

again 180-156=24

super easy remember exterior +interior angles add up to 180

Brainliest please

First angle = 105

Second angle = x

Third angle = 156 - 105

= 51

_________________________________________

Three angles of the triangle:

[tex]105[/tex]

[tex]x[/tex]

[tex]51[/tex]

___________________________________________

Angle sum of triangle = 180°

[tex]105 + 51 + x = 180[/tex]

[tex]156 + x = 180[/tex]

[tex]x = 180 - 156[/tex]

a tree of 14 m height is broken so that its top touches ground and makes an a 60 degeree.find the length of broken part of tree

Answers

Answer:

98 - 24√3 is your answer dear.

Step-by-step explanation:

Let the length of broken part of the tree = 14 - x

For finding x

sin60° = √3/2 = x /14-x

14√3 - √3x = 2x

14√3 = 2x + √3x

14√3 = (2 + √3)x

x = 14√3/(2 + √3)x

after rationalisation

x = 24√3 - 84

substract it 14 - (24√3 - 84)

YOU'LL GET 98 - 24√3 WHICH IS YOUR ANSWER.

i need help finding the value of x and the measure of each angle

Answers

Answer:

x=7, angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

+2 +2

------------------

16x = 112

÷16 ÷16

-----------------

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180

Adsila and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes, Adsila fills 11 boxes every hour. How many boxes does Carlos fill every hour?

Answers

Answer:

Carlos fills 16 boxes per hour.

Step-by-step explanation:

Given that:

Adsila and Carlos are working together to fill the gift boxes for soldiers.

Number of boxes filled while working together in 4 hours = 108 boxes

Number of boxes filled while working together in 1 hour = [tex]\frac{108}{4} = 27[/tex] boxes per hour

Number of boxes filled by Adsila every hour = 11 boxes

To find:

Number of boxes filled by Carlos every hour = ?

Solution:

Number of boxes filled every hour while working together = Number of boxes filled every hour by Adsila + Number of boxes filled every hour by Carlos

Number of boxes filled every hour while working together = 27 = 11 + Number of boxes filled every hour by Carlos

Number of boxes filled every hour by Carlos = 27 - 11 = 16

SAVINGS Natalie has $250 in her savings accountinto which she deposits $10 of her allowance each week. The balance of her savings account can be modeled by the function f(w) = 250 + 10w , where w represents the number of weeks. Write a function g(w) to represent the balance of Natalie's savings account if she withdraws $40 to purchase a new pair of shoes. Describe the translation of f(w) that results in g(w) .

Answers

Answer:

[tex]g(w) = 210+ 10w[/tex]

Step-by-step explanation:

Given

[tex]f(w) = 250 + 10w[/tex]

[tex]Withdrawal = \$40[/tex]

Required

Determine g(w)

First, we'll write an expression for g(w)

From the question, we understand that she withdrew $40 from her account balance in w weeks.

This implies that:

[tex]g(w) = f(w) - 40[/tex]

Where f(w) is the account balance in w weeks and $40 is the withdrawn amount

Substitute 250 + 10w for f(w)

[tex]g(w) = 250 + 10w - 40[/tex]

Collect Like Terms

[tex]g(w) = 250 - 40+ 10w[/tex]

[tex]g(w) = 210+ 10w[/tex]

Recall that:

[tex]g(w) = f(w) - 40[/tex]

This means that function f(w) when shifter by 40 units downward, gives g(w)
