Answer:
1.72386*10^6 km^2
Step-by-step explanation:
When I do math with scientific notation I change both to have the same exponent, then you can just do normal arithmetic. This also includes getting rid of the exponent, which I do here.
1.727*10^6 - 3140
Let's go ahead and get rid of the scientific notation for the first one. So 1.727*10^6 = 1,727,000
So now we have 1,727,000 - 3140 = 1,723,860
Since we started in scientific notation let's go back to it. 1.72386*10^6
Answer:
20!
Step-by-step explanation:
Isosceles triangles have 2 angles are the same. Since we can't do 140, because interior angles of a triangle equal 180, then we need to subtract 140 from 180. 180-140=40. 40/2 because of 2 angles=20. 20 is the angle.
Finding the product of the exponents means multiplying the exponents together, so
(W^c)^d = W^c•d
shows that rule.
Answer:
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Answer:
Step-by-step explanation:
Let s represent the length of each of the three sides mentioned. The length of the fourth side is 7 inches. Adding the lengths of the four sides together yields 10 inches: g + g + g + 7 = 10 (inches)
Then 3g + 7 = 10, or 3g = 3, or g = 1.
This equation is OK, but there's no solution, since 3g or just 3 is less than 7. With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.
