Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50,

postnew [5]

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

$x=27.50\times\frac{32}{100}$

$x=27.50\times.32$

$x=8.8$

Therefore, mark up price is $8.80.

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.

$\text{Selling price of chemistry set}=27.50+8.8$

$\text{Selling price of chemistry set}=36.30$

Therefore, the selling price of the chemistry set is $ 36.30.

There are 5 red marbles, 4 blue marble, 2 green marbles, and 1 yellow marble in the bag. What is the probability of pulling out

kykrilka [37]

Answer:

Red : 5/12

Blue : 1/3

Green: 1/6

Yellow : 1/12

Step-by-step explanation:

5 red marbles + 4 blue marbles + 2 green marbles + 1 yellow marble = 12 total marbles

5 red marbles / 12 total marbles = 5/12

4 blue marbles / 12 total marbles = 4/12 = 1/3

2 green marbles / 12 total marbles = 2/12 = 1/6

1 yellow marbles / 12 total marbles = 1/12

Answer:

The volume of P is 1728 cubic yards.

Step-by-step explanation:

For similar shapes, the ratio of volumes are defined as:

$\frac{V_{1} }{V_{2}}$ = $(\frac{h_{1} }{h_{2}}) ^{3}$

where h1 and h2 are the heights of each pyramid respectively.

We know that the scale factor of P to Q is 6:1 i.e. the ratio of heights is also 6:1. And the volume of Q is given as 8 cubic yards. so, using the relation defined above we can write:

$\frac{V_{P} }{V_{Q}}$ = $(\frac{h_{P} }{h_{Q}}) ^{3}$

$\frac{V_{P} }{8}$ = $(\frac{6}{1} )^{3}$

Vp = 6³ * 8

= 216 * 8

Vp = 1728 cubic yards

The volume of P is 1728 cubic yards.
