Answer:
The correct answer is 0.0667 centimeters.
Step-by-step explanation:
Diameter of earth is 12700 kilometers.
Width of the solidified ocean crust is 35 kilometers.
Ratio between the diameter of the earth and the solidified crust is 
.
Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.
Ratio between the diameter of the model earth and the solidified crust is 
.
But this ratio of the real Earth and its model must be equal.
∴ =
⇒ x = 0.0667 centimeters.
<span>two decimals that are equivalent to 0.700 = 0.7, 0.70
hope it helped :)</span>
Answer:
The first one is m = 2/1
The second one is m = 3/2
The third is m = 3/1
Step-by-step explanation:
Using the slope formula: m = Rise/run = y2 - y1 all over x2 - x1, they should equal the answers I have provided. You can use an two x-values or y-values.
Sorry if I am wrong... I tried... the thought is what counts! :)
Answer:
Step-by-step explanation:
chickens + goats = 13
so...
c + g = 13, so...
g = (13 - c)
2 legs times the number of chickens (2c) + 4 legs times the number of goats (4g) = 48 total legs. So...
2c + 4(13-c) = 48, so
2c + 52 - 4c = 48, so
-2c = -4, so
2c = 4, so
c = 2.
There are 2 chickens, and therefore 11 goats.
