Answer: (C)
Step-by-step explanation:
Looking at the diagram the area occurring continuously over a period of time is the constant point which ranges from -4 to -2 making the answer C
9514 1404 393
Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
Answer:
The answer is ![4.4*10^1^0 planets](https://tex.z-dn.net/?f=4.4%2A10%5E1%5E0%20planets)
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](https://tex.z-dn.net/?f=%3D6.022%2A10%5E2%5E3%20%2A%20400%5C%5C%3D2.40%2A10%5E2%5E6)
2. Now we will find the surface area of earth
![Area = 4\pi R^2](https://tex.z-dn.net/?f=Area%20%3D%204%5Cpi%20R%5E2)
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](https://tex.z-dn.net/?f=Area%20%3D%204%2A3.14%2A%282.1%2A10%5E7%29%5E2%5C%5CArea%20%3D%205.5%2A10%5E1%5E5ft%5E2)
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](https://tex.z-dn.net/?f=%3D%202.40%20%2A%2010%5E2%5E6%2F5.5%2A10%5E1%5E5%5C%5C%3D4.4%2A10%5E1%5E0%20planets)
Here is my answer.. correct me if im wrong.
