Answer: Choice B
=========================================================
Explanation:
We'll be using the converse of the pythagorean theorem.
If we had a triangle with sides a,b,c and 
was true, then we have a right triangle. Note: c is always the longest side
For the first answer choice we have: a = 5, b = 8, c = 12
Then,
which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.
Choice B on the other hand works because
We have a true statement at the end, which confirms <u>choice B</u> is a right triangle.
I think its either A or D
Hope this helps!
Assume that
a and b = the two legs of the right triangle.
c = the hypotenuse.
The area of the right triangle is 750 yd², therefore
(1/2)*a*b = 750
ab = 1500 (1)
The perimeter is 150yd, therefore
a + b + c = 150 (2)
Let the side fenced with wood be a, at $5/yd. Sides b and c are fenced with steel at $10/y. The total cost is $1200, therefore
5a + 10b + 10c = 1200
or
a + 2b + 2c = 240 (3)
From (2), obtain
c = 150 - a - b (4)
Substitute (4) into (3)
a + 2b + 2(150 - a - b) = 240
-a + 300 = 240
a = 60
From (1), obtain
60b = 1500
b = 25
From (4), obtain
c = 150 - 60 - 25 = 65
Answer:
A. The length of the leg fenced with wood is 60 yd.
B. The length of the leg fenced with steel is 25 yd.
Answer: first option.
Step-by-step explanation:
Find the common difference d of the arithmetic sequence:
Then the formula for the 101st term is the shown below:
Where:
Substitute values into the formula. Therefore, you obtain:
Answer:
Equation: ($26÷4 hours) × 25 hours
Answer: $156.25
Step-by-step explanation:
First, you would have to find out how much she earns per hour, so $26÷4. Then you multiply that by 25.
(26÷4) x 25=$156.25.
