Answer:

450 Bacteria

Step-by-step explanation:

First we need to consider the amount of bacteria that grew after two hours. Since 100 bacteria grew after 2 hours, we need to find how much bacteria grows per hour.

We can find that by dividing 100 by 2

100/2 = 50 Bacteria per hour

Now that we know how much bacteria grows per hour, we can then multiply that amount to the amount of hours asked in the problem.

9 hours x 50 Bacteria = 450 Bacteria in 9 hours.

I went to a restaurant and gave the waitress a $15 tip. If the tip was 20% of the dinner how much was the dinner?
prohojiy [21]

Answer:

Dinner only: $75

Dinner and Tip: $90

Step-by-step explanation:

If the tip was $15, and the tip was 20% of the price of dinner, then dinner was $75.

You can find this out by doing 15/20%, which should give you 75.

If the question requires you to add up the price of dinner and the tip, then the total price would be $90

>>>>>>>>> Use graphs and tables to find the limit and identify any vertical asymptotes of the functio
Fiesta28 [93]

Answer:

Step-by-step explanation:

as you can see something amazing happens in 10 in this function . If you replace x with 10 you get 1/0 wich an indetermined form in Mathematics.

Now we are sure that there is a vertical asymptote in 10. Let's see identify the limit in the left of 10.

let's assign some values to x that are smaller than 10.

1. x=9

1/(9-10)= -1

a negative value

2. x=8

1/(8-10)= -1/2

a negative value

let try a reallu colse value to 10 like 9.99

1/(9.99-10)=-100

a negative value

so we can deduce that the limit is -∞

lim     [1/(x-10)]=-∞

x→10-
