Answer:

theyre worth the same so twelve

Step-by-step explanation:

if you divide the amount youre spending then the amount youre buying you can get the price of each. therefore:

$9/12 cans = 0.75

$3/4 cans =0.75

so theyre the same amount just depends on how hungry you are

In 2009 the life expectancy is about 80 life expectancy gains 5.7 years every decade. From 2009 in how many years would humanity

Dmitry [639]

Answer:

about 70 years

Step-by-step explanation:

Life expectancy (e) improves by 5.7 years every 10 years, so 5.7/10 = 0.57 years per year. For t years after 2009, it can be modeled by ...

e = 0.57t +80

We want to find when that is 120:

120 = 0.57t +80

40 = 0.57t

40/0.57 = t ≈ 70.2

About 70 years from 2009, humanity may achieve a life expectancy of 120 years.
