Answer:

  C)  800%

Step-by-step explanation:

The markup amount is the difference between the selling price and the cost:

  markup = selling price - cost

  markup = $63 -7 = $56

The percentage markup relative to the cost is ...

  markup/cost × 100%

  = ($56)/($7) × 100%

  = 8×100% = 800%

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf.

The inequality that matches this scenario will be:

x ≥ 12.

Since there were at least 12 games, we would use the greater than or equal to sign.

Answer:

either 5 or 11

Step-by-step explanation:

(8, -12)

(5, -9) or (11, -9)

If y varies consistently with x then it would copy what happens, in a manner of speaking.

In this case, y increases by three, x would either add 3 or subtract 3

I am not completely sure on this.

Answer:

let the two number be x and y then,

x+y=12

x-y=-4

-----------

2x=8

or, x = 4 put the value of x in first equation

4+y= 12

or, y=12-4

or, y= 8 hence the two number is 4 and 8

You just have to add like values together.

Answer:

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

[tex]\frac{3}{345}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

Step-by-step explanation:

hey! keep calm okay? i got u.

Okay so for a pack of 12 confetti eggs, you pay $2.88. to find the unit price, or price for 1 egg, you just take 2.88 divided by 12 (which i already did) and you get 0.24. so the price for 1 confetti egg is $0.24 or 24 cents.

James reads 520 words in 2 minutes. Luke reads 960 words in 5 minutes. All we need to find out is how many words can they read in 1 minute? All ewe do is take 520 divided by 2, and you get 260. Then you take 960 divided by 5, and you get 192. so the rates they read at is 260 wpm and 192 wpm.

A shipping and handling fee is 35.00 right? so what you want to find is “35.00 is what percent of 437.50?” and if you think about it and go through it, 35 is 8% of 437.50. so 8% of the total is the shipping and handling fee!

good luck! i hope this helped!

Answer:

v = 6

Step-by-step explanation:

Equation: 11.5v+70=139

Answer:

9/2

Step-by-step explanation:

3/4 x 6 can be thought of as multiplying 3/4 x 6/1

When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.

3/4 x 6/1 = (3x6)/(4x1)

3/4 x 6/1 = (18)/(4)

3/4 x 6/1 = 9/2

Answer:

root3/ root2

Step-by-step explanation:

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2
