Suppose we want to choose 2 colors without replacement from the 3 colors

Rzqust [24]

Question:

Suppose we want to choose 3 colors, without replacement, from the red, blue, green, and purple.

(a)How many ways can this be done, if the order of the choices is taken into consideration?

(b)How many ways can this be done, if the order of the choices is not taken into consideration?

Answer:

(a) 6 choices

(b) 3 Choices

Step-by-step explanation:

Given:

3 Colors

Order of choice : Red, Blue, Green

(a) Order of the choices taken into consideration :

When we are picking the first colour there are 3 color choice.

When we are picking second colour there are 2 choice and so on.

Therefore, total choices are = 3*2 = 6 choices

(b) Order of the choices not taken into consideration :

When to take this option we choose as $3 \times 2$ and the remove the duplicates

Therefore, choices are = $\frac{(3 \times 2)}{(1 \times 2)}$ = $\frac{6}{2}$ = 3 Choices

Akira and a business associate agree to invest in a project estimated to cost $1.8 million (1,800,000). They decide to split the

MariettaO [177]

If it's relationship Akira : Business A. = 7:5

The part of Akira is 7k

and the part of the Business A. is 5k

Then

7k+5k=12k => 12k=1,800,000 => k= 1,800,00/12=150,000$

Akira part is 7k= 7 * 150,000 = 1,050,000$

Good luck!!!!

A company makes concrete paving stones in different sizes. Each stone has a volume of 30 cubic inches and a height of 3 inches.

Zepler [3.9K]

Answer:

There are 5 different sized paving stones that can have a volume of 360 in³.

Step-by-step explanation:

Volume = Area x height.

We are given;

volume; V = 360 in³

Height; h = 3 in

Thus, 360 = A x 3

A = 360/3 = 120 in²

This is the area of the base, so we need to find the number of different stones which have a base area of 120 in².

Let's list all the factors of 120 which are;

1,2,3,4,5,6,10,12,20,24,30,40,60,120

The question says we shouldn't use 1 or 2 in inches as length and width.

Leaving us with the remaining listed factors.

So the pair of factors that give and area of 120 are;

Size;

3 x 40

4 x 30

5 x 24

6 x 20

10 x 12

Thus, there are 5 different sized paving stones that can have a volume of 360.
