Answer:
A
Step-by-step explanation:
The volume of a rectangular prism is:

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

So, we can write:

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.
So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

Solve for t:

The correct answer is A.

Step-by-step explanation:
<h3>Answer:</h3>
A. If two lines intersect and form right angles, they intersect and form 90° angles.
<h3>Explanation:</h3>
The first conditional can be described by ...
... if p then q
where
- p = two lines intersect and form right angles
- q = the lines are perpendicular
The second conditional can be described by ...
... if q then r
where
- r = they intersect and form 90° angles.
___
The Law of Syllogism tells us that we can conclude ...
... if p then r
where p and r are as defined above. This translates to ...
... If two lines intersect and form right angles, then they intersect and form 90° angles. (matches selection A)
Answer:
x
Step-by-step explanation:
If two angles are supplementary, then
the sum of their measures is 180°.
So if the measure of an angle is 77°,
the measure of its supplement is 103°.
We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 77 or 103°.
