What is 5 4/9 + 2 15/36 as a whole or mixed number??

1 answer:

8 0

You have to add the whole numbers, which is 5 + 2 = 7. Then you add the fractions. In order to do that, you have to convert 4/9 to X/36 so 15/36 and 4/9 have the same denominator. In this case, 9 is a factor of 36, so you can multiply 4/9 by 4/4 (which is like multiplying by one). The result is 16/36. Now add the numerators 15 + 16 = 31. Denominator remains 36 because you do not change it when you add fractions.

The result therefore is 7 and 31/36.

Lin counts 5 bacteria under a microscope. She counts them again each day for four days, and finds that the number of bacteria do

Liula [17]

Answer:

The population of bacteria can be expressed as a function of number of days.

Population = $5*2^{n-1}$ where n is the number of days since the beginning.

Step-by-step explanation:

Number of bacteria on the first day= $5 * 2^{0} = 5$

Number of bacteria on the second day = $5 * 2^{1} = 10$

Number of bacteria on the third day = $5*2^{2} = 20$

Number of bacteria on the fourth day = $5*2^{3} = 40$

As we can see , the number of bacteria on any given day is a function of the number of days n.

This expression can be expressed generally as $5*2^{n-1}$ where n is the number of days since the beginning.

What is the APR of a payday loan for $1460 due in 15 days that charges a $90 fee?

Tema [17]

Charge per day = $90 / 15 = $ 6
Charge per year = $ 6 * 365 1/4 ( If the year contains 365 1/4 days) 
= $ 2191.5 
As a percentage = 2191.5 / 1460 * 100 = 150 %
