Answer:

Step-by-step explanation:

10 contain both chocolate and caramel

There are 18 candies.

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

The diameter of the moon is approximately one fourth of the diameter of the earth.

netineya [11]

Answer:

Step-by-step explanation:

Area of a sphere is $4\pi d^{2}$

let d be the diameter of the moon and D be the diameter of the earth

d = 1/4 D

Area of Earth = $4\pi D^{2} = 4\pi (\frac{d}{4} )^{2} = 4\pi \frac{d^{2} }{16} = \pi \frac{d^{2} }{4}$

Area of moon = $4\pi d^{2}$

$\frac{Area of moon}{Area of Earth} = \frac{1}{16}$
