Answer:
49145 years
Step-by-step explanation:
In a certain country the life expectancy for women in 1990 was 45 and in 2000 it was 85?years.
Assuming that life expectancy between 2000 and 2100 increases by the same percentage as it did between 1900 and 2000,what will life expectancy be for women in 2100?
In 10 years, the expectancy increased by 85/45 = 17/9
between 2000 and 2100, it will increas by 10 time 10 years, so expected expectancy is years
Answer:
see below
Step-by-step explanation:
Pi is approximately 3.14

Answer:
AB is parallel to AC
Step-by-step explanation:
the product of the gradients of perpendicular line should be -1
AB=2/3
AC=-3/2
2/3*-3/2=-1
=-1
The answer would be, "25.5".
Answer:
113.04
Step-by-step explanation:
Area of a circle is π x .
I'm assuming that you're using 3.14 as π.
Since the radius of the circle is 6 m, all you need to do is plug it in!
Area = 3.14 ×
Area = 3.14 × 36
Area = 113.04 , which is the third answer choice.
