A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6

ddd [48]

Answer:

The population of bacteria after 6 days is 2,313.06

Step-by-step explanation:

Given as :

The initial population of bacteria = i = 1,000 bacteria

The growth rate of bacteria per day = 15%

Let The population of bacteria after 6 days = f

The time period of growth = 6 days

Now, According to question

The population of bacteria after 6 days = initial population × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

Or, f = i × $(1+\dfrac{\textrm r}{100})^{\textrm t}$

Or, f = 1000 × $(1+\dfrac{\textrm 15}{100})^{\textrm 6}$

Or, f = 1000 × $(1.15)^{6}$

Or, f = 1000 × 2.31306

∴ f = 2,313.06

So,The population of bacteria after 6 days = f = 2,313.06

Hence,The population of bacteria after 6 days is 2,313.06 Answer

Pls help! On the day of the big game, 298 marching band members were waiting to get on the

elixir [45]

Answer:

here u go!

Step-by-step explanation:

each bus can fit 45 people and there are 298 TOTAL. there will be an extra bus with less than 45 people btw.

first divide 298 by 45, you will get 6.2 something. however, you CANNOT have .2 of a bus. the 6 represents 6 buses of 45 people.

now taking that 6 again, multiply it by 45. 45 x 6 = 270. we have 28 people left over, this adds an extra bus.

7 buses will be needed to get them to the game.
