Answer: 6 hours
Step-by-step explanation:
Given, Tim and Jim are working on a school project together.
Tim takes 10 hours to complete the school project.
If Jim worked alone, it would take him 15 hours
Let t be the time they both take if they work together.
Then, 

So, it will take<u> 6 hours</u> to complete the school project together .
Think the quality of it is based off of the amount of time some one worked on something. 2. If all of the data values in the class were compiled in a giant histogram, and a curve was drawn over the graph, where should the highest point on the curve occur? It should be were the mode is because there is the most of the mode in the data set. 3. What phase(s) of a design process might statistics be most applicable? The revising stage. 4. Other than dial calipers, what kinds of tools are used to precisely measure objects for purposes of quality control? A ruler/ measuring tape or you can use a scale and you could measure well.
Answer: A hexagon has 6 lines of symmetry.
No, it will not be able to make a right triangle.
<em><u>Solution:</u></em>
Given that,
Joel wants to fence off a triangular portion of his yard for his chickens.
The length of three peices of fencing are 8 feet , 15 feet and 20 feet
For making it a right triangle it must satisfy the "Pythagorus theorem"
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
For a right angled triangle with sides a, b, c

Given sides are:
a = 8 feet
b = 15 feet
c = 20 feet
Substituting the values in above formula

Since the pythogoras formula is not satisfied, the given sides cannot form a right angled triangle
Thus , No, it will not be able to make a right triangle.
There are a lot but when I think of it I think -14+0
