Which of these number is irrational?the square root of 36
the square root of 49
the square root of 13
the square root of 121

Answers

The answer is the square root of 13 because it is the only one that gets square rooted and does not come out even. Hope this helped.
The square root of 36 is 6, the square root of 49 is 7, the square root of 121 is 11. So the answer is the square root of 13.

Are the rations 3:6 and 6:3 equal why or why not?

Answers

Answer: No.

Step-by-step explanation:

    No, these ratios are not equal. We can view these ratios as fractions and divide to see if they are equal.

         3:6 = (3)/(6) = 0.5

         6:3 = (6)/(3) = 2

    No, 0.5 ≠ 2.

Three weeks ago John bought stock at 491/4; today the stock is valued at 497/8. We could say the stock is performing at which of the following?A. Below par
B. Above par
C. On par
D. Par equality

Answers

Rate at which John bought the stocks 3 weeks ago = 491/4
Rate at which John sold the stock = 497/8
Amount of loss incurred by John = (497/8) - (491/4)
                                                    = (497 - 982)/8
                                                    = - (485/8)
From the above deduction it can be easily said that the stock is performing below par. The correct option among all the options that are given in the question is option "A".

The Correct Answer Is B- Above Par

Colby and Jaquan are growing bacteria in an experiment in a laboratory. Colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. Jaquan has a different type of bacteria that doubles every 3 hours. How many bacteria should Jaquan start with so that they have the same amount at the end of the day?

Answers

Here's the general formula for bacteria growth/decay problems

Af = Ai (e^kt)

where: 
Af = Final amount
Ai = Initial amount
k = growth rate constant
t = time

But there's another formula for a doubling problem.
kt = ln(2)

So, Colby (1)
k1A = ln(2) / t
k1A = ln(2) / 2 = 0.34657 per hour.

So, Jaquan (2)
k2A = ln(2) / t
k2A = ln(2) /3 = 0.23105 per hour.

We need to use the rate of Colby and Jaquan in order to get the final amount in 1 day or 24 hours.

Af1 = 50(e^0.34657(24))
Af1 = 204,800

Af2 = 204,800 = Ai2(e^0.23105(24))
Af2 = 800

Answer:

800
