Answer:
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
We already know the slope so, so far the equation should look like this.
Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:
when you solve this equation you'll get b
So the equation is
The area of the triangle is 14.1 square meters
<h3>How to determine the triangle area?</h3>The side lengths are given as:
5m, 6m and 9m
Calculate the semi-perimeter (s) using
s = (5 + 6 + 9)/2
Evaluate
s = 10
The area is then calculated as:
This gives
Evaluate the products
Evaluate the exponent
Area = 14.1
Hence, the area of the triangle is 14.1 square meters

Answer: 2.5 or 2 1/2
Step-by-step explanation:
You can convert the mixed fractions to decimal numbers:
- Divide the numerator by the denominator of the fraction.
- Add the result to the whole number.
Thenyou have:
Barbara's time:
Donna's time:
Cindy's time:
Nicole's time:
As you can see, the fastest girl is Cindy and the slowest girl is Nicole.
Then, you must make the following subtraction to calculate the difference:
or 2 1/2
