Answer:
25.2 weeks until everyone on the planet is infected
Step-by-step explanation:
The number of infected people after t weeks has the following format:

In which P(0) is the initial number of infected people and r is the growth rate, as a decimal.
The number of infected people doubles every week
This means that 
So




So

200-person town
This means that 
So


How long will it be until everyone on the planet is infected?
This is t for which P(t) = 7700000000[/tex]
So







25.2 weeks until everyone on the planet is infected
For this case we have the following definition:
tens place: number of two digits whose absolute value is greater than zero.
Then, we have the following rounding rule:
If the previous number is greater than or equal to five, the next number increases by one unit.
We then have the following numbers rounded to 30 when rounded to the nearest ten:
26: twenty-six
27: twenty-seven
Answer:
two different numbers that round to 30 when rounded to the nearest ten are:
26: twenty-six
27: twenty-seven
90 is almost 100 so ima go wid 2
