Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
                                      = 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
           = 8.57  minutes
           ≈ 9 minutes

Answer:

B. The two lines are neither parallel nor perpendicular.

Step-by-step explanation:

First, put both lines into the same format. In this example, we're going to use y=mx+b format.

x - 4y = -9

-4y = -x + -9

y = (-x + -9) / -4

y = (x+9)/-4

y = (-1/4)x + (-9/4)

y = 3x - 7

If two lines are parallel, they have the same slope. (ie 4 and 4)

If two lines are perpendicular, one line's slope is the negative reciprocal of the other. (ie 4 and -1/4)

Neither is true here.

Carol used 114 cups of flour in 2 muffins. How many cups of flour are needed to make 12 similar muffins?
son4ous [18]

Answer:

7 1/2 cups

Step-by-step explanation:

If Carol uses 1 1/4 cups of flour for 2 muffins, then she will need to repeat this conversion 6 times since she wants to make identical 12 muffins in all.

So, 1 1/4 * 6 = 7 1/2

Therefore, she needs 7 1/2 cups of flour

Hope that helps! :)
