Find the factors of 42 show and explain your work and list the factor pairs in a table

Answers

Answer 1

Answer:

Answer:

The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Step-by-step explanation:

The given number is 42.

The numbers that can divide 42 completely, are the factors of 42.

Since we know that 42 is completely divisible by 1, 2, 3, 6, 7, 14, 21 and 42, therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

The list of factor pairs are shown below:

$1* 42=42$

$2* 21=42$

$3* 14=42$

$6* 7=42$

Therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Answer 2

Answer: Factors of 42 are...
1, 2, 3, 6, 7, 14, 21, and 42.
1 x 42 = 42
2 x 21 = 42
3 x 14 = 42
6 x 7 = 42

Don't know how you want your table.
I'm sure you can do it yourself.

Mario ordered a pizza for dinner when it arrived, mario quickly ate 1/8 of the pizza. while mario went to go get napkins. his pet poodle ate 1/3a.) write a numerical expression to show the fraction of the pizza that is left

Answers

The first thing to do is to make the denominators the same:
1 X 3 = 3. 8 X 3 = 24
1 X 8 = 8. 3 X 8 = 24

3/24 + 8/24 = 11/24

The whole pizza is 1. The one can be written as a fraction:
1/1

1 X 24 = 24

24/24 - 11/24 = 13/24

24/24 - (3/24 + 8/24) = 13/24

1/8+1/3=](3)(1)+(1)(8)]/[(8)(3)]=13/24

Estimate the solution to the system of equations.
2x+3y=6
-4x+3y=12

Answers

The solution is:

$x=-1, y=2(2)/(3)$

Step-by-step explanation:

Given

2x+3y=6 Eqn 1

-4x+3y=12 Eqn 2

Subtracting equation 2 from equation 1

$2x+3y-(-4x+3y)=6-12\n2x+3y+4x-3y=-6\n6x=-6\nDividing\ both\ sides\ by\ -6\n(6x)/(6)=(-6)/(6)\nx=-1$

Putting x=-1 in equation 1

$2x+3y=6\n2(-1)+3y=6\n-2+3y=6\n3y=6+2\n3y=8\nDividing\ both\ sides\ by\ 3\n(3y)/(3)=(8)/(3)\ny=2(2)/(3)$

The solution is:

$x=-1, y=2(2)/(3)$

A company makes concrete paving stones in different sizes. Each stone has a volume of 360 inches and a height of 3 inches. the stones have different lengths and widths. how many different paving stones each with different base and a volume of of 360 cubic inches?

Answers

Answer:

The answer is 6.

Step-by-step explanation:

Given is that the total volume is 360 cubic inches

The height is fixed at 3 inches

So, total area will be = $(360)/(3)=120$ square inches.

Let's assume the minimum size in any dimension to be 3 inches.

Now we have to find possible combinations of numbers greater than 2 that will make 120. So, we have

3 x 40

4 x 30

5 x 24

6 x 20

8 x 15

10 x 12

These have the same answer in reverse order as well. So we will consider these.

Therefore, there are 6 different paving stones with different base.

Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website. Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription

Answers

Answer:

Last month's income: $1000

This month's income = $1200

Step-by-step explanation:

Number of subscribers for last month = 100

Fee per subscriber = $10

Sol, last month's income = 100(10) = 1000

This month, 30 new members joined and 10 of the existing members cancelled their subscription.

So, number of subscribers this month = 100 + 30 - 10 = 120

This month's income = 120(10) = 1200

Last month, Kiersten earned $1000 (wow that's a lot of money :3) and this month, she earned $1200.

Your bank gives you a special loan of $112,000. At the end of 30 years, you will pay the bank $176,400 in simple interest. What is the annual interest rate on your loan?

Answers

In the given problem there are several information's worth taking note of. Based on these information's the rate on the loan can be calculated.It is already given that the Principal amount is $112000. Time is given as 30 years and the final amount as $176400.
Now we have to find the amount of interest first
Interest amount = (176400 - 112000) dollars
   = 64400 dollars
As per the formula of simple interest we know that
Interest = Principal * Rate of interest * Time
Rate of Interest = (Principal * Time)/Interest amount
      = (112000 * 30)/64400
      = 3360000/64400
      = 52.17
So the rate of interest on the loan for the period of 30 years was 52.17%
