Answer:

2.4 hours or 2 hours and 24 minutes

Step-by-step explanation:

Jack mows 1/6 of the lawn per hour while Marilyn mows 1/4 of the lawn together. Adding up those rates yields in their combined mowing rate:

R = \frac{1}{6}+ \frac{1}{4}\\R=\frac{10}{24}

The time required for them to mow the entire lawn is:

t = \frac{1}{R}\\t = \frac{1*24}{10}\\ t=2.4\ hours

It would take them both 2.4 hours to mow the lawn together.

How do I make a linear function, what is a linear function?
mixer [17]

Answer:

I have uploaded a picture so you could understand it a little more.

A linear function is when there is a table that gives numbers that represent a function, as shown in the picture.

In the Image, there is a table with a x and y column. And in both columns, there are numbers.

This is what the table looks like in the picture:

<u>  x   y   </u>

0    4                       The key is y = 2x + 4

1     6 <------      lets grab the number 1 in the x column and lets

2    8       multiply it by two.  Now add four to it, and we will

3    10                  have the number 6 in the y column.

4    12


I hope I helped you! God bless :-)

What is the quotient? startfraction n 3 over 2 n minus 6 endfraction divided by startfraction n 3 over 3 n minus 9 endfraction
bazaltina [42]

The quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3

<h3 /><h3>How to solve fraction</h3><h3 />

n³ / (2n - 6) ÷ n³ / (3n - 9)

  • multiply by the reciprocal of n³ / (3n - 9)

= n³ / (2n - 6) × 1 / n³ / (3n - 9)

= 2n - 6 / 3n - 9

= 2(n - 3) / 3(n - 3)

= 2/3

Therefore, quotient of the fraction n³ / (2n - 6) ÷ n³ / (3n - 9) is 2/3
