How many months are in 6 years?

Answers

In one year, there are 12 months. So, to find out the amount of months there are in 6 years, all we need to do is multiply 12 * 6.

12 * 6 = 72

And that is our answer.

There are 72 months in 6 years.
Hope that helped =)

We can see here that there are 72 months in 6 years. It is gotten by multiplying 12 months by 6 years.

What is month?

A month is a unit of time commonly used in calendars to divide a year into shorter periods. It is based on the approximate time it takes for the Moon to orbit the Earth, which is roughly 29.5 days. To account for the varying lengths of months, the Gregorian calendar, the most widely used civil calendar, has months of different durations: 28, 30, or 31 days.

To calculate the number of months in a given number of years, you multiply the number of years by 12 since there are 12 months in a year. Therefore, 6 years multiplied by 12 months equals 72 months.

Answer is 6 (D)

45 - 39 = 6
39 - 33 = 6
33 - 27 = 6

Answer:

A. - 6

Is the common difference

see the expressions below that prove so.

Step-by-step explanation:

The sequence shows -6 to each number is same as k-6 or even n-6

we use such letters to represent 1 value. Also the reason it is a negative number is because the numbers are decreasing within the sequence.

The nth expression is the first term equation shows -6n

and the number prior to 45 is  45+6 = 51

Put together this creates our nth term =   -6n + 51

The next term is where we use the common difference also.

next nth term =  (27) + (- 6) = 21   and so on proves it the 5th term

5th nth term = -6 x 5 +51 = 21

100th nth term = -6 x 100 +51 = -549

A town had about 2120 acres of pine trees 40 years ago. Only about 13% of the pine trees remain. How many acres of pine trees remain? Round your answer to the nearest tenth.

Answers

There will be 275.6 acres of pine trees are left out of 2120 acres

Data;

  • Number of acres = 2120
  • percentage left = 13%

Percentage

To calculate the percentage of a value, we find the value of that value to it's total value multiplied by 100.

To find 13% of 2120,

(13)/(100)= (x)/(2120)\n 100 * x = 13 * 2120\n 100x = 27560\n(100x)/(100) = (27560)/(100)\n x= 275.6 acres

From the calculations above, only 275.6 acres of pine trees are left out of 2120 acres.

To calculate 13% of 2120, we multiply by 13/100.  13/100*2120=13*21.2, or 275.6 using basic multiplication.

Point O is between points G and D on line m. Which of the following statements is not necessarily true?a. O, G and D are collinear.
b. O, G and D are coplanar.
c. GO + OD = GD
d. GO = OD

Answers

Answer: d. GO = OD

Step-by-step explanation:

Given: Point O is between points G and D on line m.

It means that they are on same line m.

We know that collinear points are the points lie in the same line.

Hence O, G and D are collinear.

Also, coplanar points are the points lie in the same plane.

Since if three points are collinear, then they are coplanar.

Therefore, O, G and D are coplanar.

The statement which is not necessarily true is d. GO = OD because it is not given that o lies exactly middle to points G and D.

c. GO + OD = GD

Which shows the numbers in order from least to greatest? 


A. 1.4, 1.38, 1 3/7



B. 1.4, 1 3/7, 1.38




C. 1 3/7, 1.38, 1.4



D.
1.38, 1.4, 1 3/7
Help Me 10 Pts.

Answers

D.

1 3/7 = 1.43

therefore from least to greatest it would need to be 
1.38,1.4,1.43

or in the question

1.38, 1.4, 1 3/7

Therefore the answer would be D.

Hope this helps!
D. because 1 3/7 is equal to 1.42..... it's bigger than 1.38 and 1.4 and 1.4 is bigger than 1.38.
hope that helps!
