15 into thirds would be 15 divided by three. This would be 5. If you take 14 and divide it in half you get 7. Then subtract 5 from 7 and you get 2. The answer is 2.
Answer:
20
Step-by-step explanation:
Divisors of 100
1, 2, 4, 5, 10, 20, 25, 50, 100
You can use Heron's formula to do this
Area of triangle = sqrt[ s(s-a)(s-b)(s-c) ] where s = half the perimeter of the triangle =
1/2 * 13+5+9 = 13.5
so required area = sqrt [ (13.5)(13.5-13)(13.5-5)(13.5-9)]
= 16.1 square meters
Answer:
The line has a slope of -1.
Step-by-step explanation:
To solve for the slope of the line, use the rise over run formula. The rise over run formula is a measure of how much something changes vertically compared to how much it changes in the horizontal direction. The rise over run formula calculates the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). The formula looks like
, but in terms of finding a slope, it looks like
.
For finding the slope of this line with the points (-3,5) and (5,-3), start by writing down the information given from the question.




Next, plug in the information given from the question into the formula, and the formula will look like
. Then, simplify the equation, which will look like
. The final answer will be -1.
