Complete the sentence.

Over [174]

Answer:

Step-by-step explanation:

The horizontal asymtote is when there are no solutions for x, so it is when y = -10.

This is because when y = -10, 0.8^x must be 0, but this is impossible. You can test this by trying 4^x/5^x. It will get super small, but never 0.

Hunter had seven gallons of water in the refrigerator. Of those, two and one-fourth gallons were spring water and one and one-fi

Crank

Answer:

3 11/20

Step-by-step explanation:

Total gallons of water=7

Spring water=two and one-fourth gallon=2 1/4

Filtered water=one and one-fifth

=1 1/5

Spring water+filtered water=2 1/4 + 1 1/5

=9/4+6/5

= 45+24/20

=69/20

=3 9/20

How many gallons of water were not spring or filtered

=Total gallons- (spring+ filtered water)

=7-69/20

=140-69/20

=71/20

=3 11/20

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.

faust18 [17]

Answer:

a. Tim has completed a greater amount of work.

b. Together they have completed $\frac{142}{143}$ part of two projects.

Step-by-step explanation:

Let us assume that the project on which Jaime and Tim are working has x amount of space.

Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.

Therefore, Jaime has completed $\frac{5x}{11}$ amount of space and Tim has finished $\frac{7x}{13}$ amount of space.

a. Now, (7x) \times 11 > (5x) \times 13

⇒ $\frac{7x}{13} > \frac{5x}{11}$

Therefore, Tim has completed the greater amount of work. (Answer)

b. Together they have completed $(\frac{7x}{13} + \frac{5x}{11}) = \frac{(7 \times 11 + 5 \times 13)}{13 \times 11} x = \frac{142}{143}x$ amount of space out of 2x amount of space. (Answer)
