Darya [45]

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 $85*(\frac{85}{45})^{10} = 49145$ years

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.

REY [17]

Answer:

$x=\sqrt{10}$

Step-by-step explanation:

The given equation is :

$5-2x^2=-15$

We need to solve it using inverse operations.

Subtract 5 from both sides of the equation.

$5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}$

So, the solution of the given equation is $x=\sqrt{10}$ .
