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)

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
