45.50(original price) * .8 (discount) * 1.05 (tax) =$38.22(final answer)

Answer:

38.22

Step-by-step explanation:

Remark

You take the discount first. Most places apply a sales tax only when money changes hands (or it should be that way).

Discount

45.50 * 20/100 = 9.10

45.50 - 9.10 = 36.4

Sales Tax

46.4 * 5/100 = 1.82

Total Cost

Total Cost after the discount = 36.4 + 1.82 = 38.22

When the manager of Fantastic Furniture buys a sofa from a manufacturer, she uses a markup of 45% of her cost to set the selling price of the sofa. What will be the selling price if the manager of Fantastic Furniture buys a sofa for $400? Show your work explain your reasoning.

Answers

Answer:

Selling price= $580

Step-by-step explanation:

eGiving the following information:

Buying price= $400

Mark-up percentage= 45% = 0.45

The manager applies a mark-up equivalent to 45% of the buying price. First, we need to determine how much is 45% of the cost.

Mark-up= buying price* Mark-up percentage

Mark-up= 400*0.45

Mark-up= $180

Now, the selling price:

Selling price= 400 + 180

Selling price= $580

A building casts a shadow 100 m long. At the same time, a nearby pole 4 m high casts a shadow 8 m long. What is the height of the building? Round your answer to the nearest tenth, if necessary.

Answers

Answer:

50m

Step-by-step explanation:

Calculation for the height of the building

First step:

Let x represent the building height

Second step:

100m/8m = x/4

Third step is to Cross multiply:

100m(4) = 8x

400m= 8x

x=400m/8

x=50m

Therefore the height of the building will be 50m

The value of x is 63.435, which is 60 round to the nearest tenth of a degree.

Given:

Height = 40 feet.

Distance =20 feet.

To find the value of x.

sinθ = hypotenuse/opposite.

cosθ =  hypotenuse/adjacent.

tan θ = opposite/adjacent.

tan θ = 40/20 = 2

θ = tan ⁻(2) = 63.435

Therefore, 60 for x round to the nearest tenth of a degree.

The correct answer is y < 18. Let's pretend a student forgot to flip the symbol and they mistakenly believe the solution set is y > 18. They check 21 since 21 is greater than 18, and they think that y has to be greater than 18. When they do their check, what will the final line of the check say? Is this a true statement?

Answers

Answer:

It is wrong

Step-by-step explanation:

y < 18

This is read as y is less than 18. If the students forgot to flip the symbol and mistakenly believe that y > 18.

y > 18

This is read as y is greater than 18.

There is a difference between the numbers greater or less than 18 .

y must have numbers less than 18 and 21 is greater than 18.

Therefore it is wrong.

But to make it true we can multiply minus with the inequality y > 18

-y > -18

This reverses the inequality sign and it becomes

y< 18

In the function y = x, if y = -8, what is x equal to?

Answers

Answer:

x = -8

Step-by-step explanation:

[tex]y =x[/tex]

If y = -8 — Substitute y = -8 in the equation.

[tex] - 8 = x[/tex]

Therefore, our x is -8 when y = -8

Answer:

x=-8

Step-by-step explanation:

Let's solve your system by substitution.

y=x; y=−8

Rewrite equations:

y=−8; y=x

Step: Solve y=−8 for y:

y=−8

Step: Substitute −8 for y in y=x:

y=x

−8=x

−8+−x=x+−x(Add -x to both sides)

−x−8=0

−x−8+8=0+8(Add 8 to both sides)

−x=8

-x/-1 = 8/-1

x=-8

2 trains leave from the same point and travel along straight tracks that differ in direction by 72゚. If their speeds are 64 miles per hour and 52 miles per hour approximate how far apart they will be after 30 minutes

Answers

Answer:

34.44 miles

Step-by-step explanation:

Distance covered bty the two trains :

Distance = speed * time

Time = 30 minutes = 0.5hr

Distance of train 1 = 64 * 0.5 = 32 miles

Distance of train 2 = 52 * 0.5 = 26 miles

Included Angle = 72°

Using cosine rule :

a² = b² + c² - 2bcCosA

Let Distance between the trains after 30 minutes = a

a^2 = 32^2 + 26^2 - 2(32)(26) * Cos(72)

a^2 = 1700 - 514.20427

a^2 = 1185.7957

a = sqrt(1185.7957)

a = 34.435

a = 34.44 miles

Find the area of the shaded sector. Round to the nearest hundredths place.
SR= 26 m

Answers

Answer: 315.45 m^2

Step-by-step explanation:

We know that the area of a circle is written as:

A = pi*R^2

Where:

pi = 3.14

R = radius of the circle.

In this case, we know that SR (the diameter) is equal to 26m

And the radius is half of the diameter, then:

R = 26m/2 = 13m

Now, in the image we can see that we have half of the circle shaded, the area of that part will be equal to half the area of a complete circle, then the area of that part is:

A = (1/2)*3.14*(13m)^2 = 265.33 m^2

We also can see that we have a small arc shaded.

The area of a given arc of an angle θ, is given by:

A = (pi*R^2)*(θ/360°)

Now we want to find the angle of this arc, that is the angle:

∠PQ

We know that:

∠SR = 180°   (this is a straight line)

∠RQ = 73°

and i assume that:

∠PS = 73°

if we look at the image, we can see that we must have:

∠QR + ∠PQ + ∠SP = ∠SR

73° + ∠PQ  + 73° = 180°

∠PQ = 180° - 2*73° = 34°

Then the area of the small arc is:

A' = (3.14*(13m)^2)*(34°/360°) = 50.12 m^2

The total shaded area is equal to the sum of the two areas we calculated, this is:

Total area = A + A' = 265.33 m^2 + 50.12 m^2 = 315.45 m^2
