Answer:

4.2 miles

Step-by-step explanation:

Martina runs 6 miles in 50 minutes, we have to find the rate at which she is running. Put it in a fraction \frac{6}{50} or she runs 6 miles every 50 minutes. When we divide we get that she is running, 0.12 miles evrey minute. The question askes us how far Matina will run in 35 minutes, so we multiply 0.12 by 35, and we get that she will run 4.2 miles.

Pat can mow the grass on the football field in 45 minutes. Jordan can mow
Basile [38]

You set up the equation like this:

T/45+T/53=1

You find the least common factor of 53 and 45 and times both sides so you end up with this:

53T+45T= least common factor

Then add up 53T and 45T.

98T= least common factor

Then divide 98 from both sides. That will be your answer.

Sorry I didn't have enough time to find the least common factor but it is a number that they both go into. I would check to make sure I'm correct. I hope this helps!

Find the slope of the line that passes through (10, 8) and (1, 9)?
sdas [7]

Answer:

The answer is

<h2>-  \frac{1}{9}</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(10, 8) and (1, 9)

The slope is

m =  \frac{9 - 8}{1 - 10}  =  \frac{1}{ - 9}  \\  =  -  \frac{1}{9}

We have the final answer as

-  \frac{1}{9}  \\

Hope this helps you
