<u>Answer:</u>
W = 30T + 500
<u>Step-by-step explanation:</u>
We are given that water is added in the pond at a rate of 30 liters per minute and there are total 500 liters in the pond to start.
So assuming W to be the amount of water in the pond (in liters) and T to be the the number of minutes that water has been added, we can write an equation:
W = 30T + 500
(W on the y-axis and T on the x axis)
<h3>Answer: Choice A</h3>
========================================================
Explanation:
The left side simplifies to
since
The right side is also 100 because
So is a true equation because both sides are the same number.
Therefore, a triangle with sides 6,8,10 is a right triangle. The hypotenuse 10 is the longest side opposite the 90 degree angle. In other words, the 90 degree angle is between the sides 6 ft and 8 ft.
So this is why choice A is the final answer.
-----------
Choice B is false because the inequality becomes
which is also false. Even if that inequality was true, we can't use it to form a right triangle. We need both sides to be equal.
Choice C is false because we need to have both sides equal to the same number. We need to have to be true if we want a right triangle with sides a,b,c.
Choice D is false because of the phrasing "Draw any two of the sides with a right angle between them". The 90 degree angle must go between the 6 and the 8, and nowhere else.
