Answer :

Bacteria B started with 3000 bacteria.

Bacteria B doubles every hour.

In three hours, the amount of Bacteria A will be greater than the amount of Bacteria B.

Bacteria A: f(x)=  1000 *3^x

x=0 , y = 1000

x=1 , y = 3000

x=2 , y = 9000

x=3 , y = 27000

Bacteria A: f(x)=  3000 *2^x

x=0 , y = 3000

x=1 , y = 6000

x=2 , y = 12000

x=3 , y = 24000

From this table we can see that Bacteria B started with 3000 bacteria.

Bacteria B doubles every hour, 3000, 6000, 12000, 24000

In 3 hours , Bacteria A = 27000 and Bacteria B = 24000

So,In three hours, the amount of Bacteria A will be greater than the amount of Bacteria B.

Darlene has 59 pages to type. so far she gas type 23 pages. what fraction of the job is finished ​
coldgirl [10]

Answer:

\frac{23}{59}

Step-by-step explanation:

A fraction can be found be taking the current amount over the total amount:

\frac{current}{total}=\frac{23}{59}

Since Darlene has only typed 23 pages out of 59, her fraction is 23 over 59.  Fractions must always be in simplest form, which means that both the numerator and denominator can no longer be divided by the same factor.  Since the numbers 23 and 59 are both prime and have no other factors other than 1 and themselves, the fraction 23/59 is in simplest form.

What is the volume of this rectangular prism? <br> 3ft by 6 1/4 ft by 14 ft
Liula [17]
We can find the volume of any rectangular prism by simply multiplicating its height, length and width.

Also, lets change that 6 1/4 to 6.25, or 25/4 if you like. I’m gonna use 6.25.

If we take volume as “V”, then:

V = L * W * H
V = 3ft * 6.25ft * 14ft
V = 262.5 ft^3 (Its ft cubed because we multiplied by ft three times.)

To get from the stone to the tree you must avoid walking through a pond. To avoid the pond, you must walk 34 yards north
AlexFokin [52]

Answer:

Rounded, 22 yards.

Step-by-step explanation:

The pythagorean theorem states: a^2 + b^2 = c^2

a = 34, squared = 1156

b = 41, squared = 1681

Add those to get 2837.

√2837 = 53.26, rounded.

34 + 41 = 75

75 - 53 = 22

22 yards is your answer.
