There were 90 runners just start a race in the first half of the race 1/3 of them dropped out in the second half of the race 1/5

Eva8 [605]

Answer:

6 runners finished the race

Step-by-step explanation:

it starts with 90 runners. then 1/3 of them dropped out in the second half of the race, that means you do 90 divided by 3

90 ÷ 3 = 30

Then, 1/5 of the runners remained.

That means you do 30 divided by 5

30÷ 5= 6

so the answer is 6 remaining runners finished the race.

A mole of 1 gallon cans of paint could cover every square inch of the surface of how many planets the size of the earth?

Nady [450]

Answer:

The answer is $4.4*10^1^0 planets$

Step-by-step explanation:

We ll have to find more information first to solve this question.

1. One mole = 6.022 x 10^23

Assuming one gallon of paint covers the 400 sq ft of area.

Thus total area which can be covered by 1 mole of gallon is

$=6.022*10^2^3 * 400\\=2.40*10^2^6$

2. Now we will find the surface area of earth

$Area = 4\pi R^2$

The radius of earth is 2.1 x 10^7 Feet

substituting values

$Area = 4*3.14*(2.1*10^7)^2\\Area = 5.5*10^1^5ft^2$

3. Now we will find out the number of planets of earth size which can be covered by mole of gallon of paint

= Total area one mole of gallon can cover / area of earth

$= 2.40 * 10^2^6/5.5*10^1^5\\=4.4*10^1^0 planets$
