Maria is a florist in a small boutique. If Maria paid her supplier 8.50$/dozen for roses and sold them for 19.95$, what was the mark up in percent?

Answers

Answer:

The markup percentage was 135%.

Step-by-step explanation:

In order to find the markup percent, you have to take the sales price minus the cost and divide that by the cost. Then, you have to multiply by 100 to establish the markup percentage:

markup percentage=((19.95-8.50)/8.50)*100

markup percentage=(11.45/8.50)*100

markup percentage=135%

According to this, the answer is that the markup percentage was 135%.

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°

Answers

Answer:

x = 84

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the given angles and equate to 360

x + 132 + 54 + 90 = 360

x + 276 = 360 ( subtract 276 from both sides )

x = 84

Answer:

x = 84°

Step-by-step explanation:

→ Recall the fact that angles around a point add up to 360°

360 - (90 + 54 + 132 ) = x

→ Simplify

360 - 276 = x

→ Simplify again

84 = x ∴ x = 84°

(a) An angle measures 51°. What is the measure of its complement?
(b) An angle measures 113°. What is the measure of its supplement?

Answers

Step-by-step explanation:

For a

Let the another angle be x then

x + 51° = 90° {being complementary angles }

x = 90° - 51°

x = 39°

For b

Let the another angle be x then

x + 113° = 180° {being supplementary angles }

x = 180° - 113°

x = 67°

What is the greatest surface area of a rectangular solid that can be built from 16 identical unit cubes?

Answers

Answer and explanation:

The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.

We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes

Surface area is therefore 16×6a²

y = 8x
y = 4x + 8

Answers

Answer:

y = 16

x = 2

Step-by-step explanation:

y = 8x

y = 4x + 8

then, by substitution:

8x = 4x + 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2

y = 8x

y = 8*2

y = 16

Check:

y = 4x + 8

y = 4*2 + 8

16 = 8 + 8

A pizza store sold 36 pepperoni pizzas in a day, which was 24% of their pizza sales.
What was the total number of pizzas sold that day?

Answers

Answer:

150 pizzas

Step-by-step explanation

36 pizzas are equivalent to 24% so i divided both sides by 4 which gave me 9 pizzas  for 6% . But 6 cannot fully fit into 100 so it will have to be a decimal i did 100 divided by 6 so i would know what i would have to divide both sides by which gave me  50/3 which was 16.66666667 which when i times by 9 by it gave me 150 pizzas

Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16

Answers

Answer:

x= - 9

Step-by-step explanation:

- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9

Hey there!

Use the Distributive Property and simplify:

-8(x+7)=16

-8x-56=16

Notice we write -8 right next to x.

Add 56 to both sides:

-8x=16+56

-8x=72

Divide both sides by -8:

x=-9

Hope everything is clear.
