Can someone please help 1. Suppose the number of bacteria growing in a culture dish doubles every 6 hours. If the culture dish initially contains 250 bacteria, how many bacteria are in the dish after 18 hours?

2. The population of bacteria in your messy room is 36,725 and is growing at a rate of 11% each month. What would the population be after 6 months if you don’t clean your room?

3. The current popularity of the Kardashians is about 82,302 fans. Sadly, this is falling at a rate of 50% each year. How many fans will the Kardashians have in 4 years?
Equation:
Solution:

#1: 1000

because there are 3 sets of 6 hours in 18 hours, so for each of those sets you would take your number, which at first is 250 and double it which makes 500 then you double that to 1000

thats the first one for you, it seems as if it says you are in high school so you should know this simple math :). keep trying! and try getting a calculator before asking. (yes i'm to lazy to do the rest)

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
