We have been given that a bucket holds 121.4 ounces (oz) of water when full.
Further, we know that the bucket loses 0.04 oz of water per second.
We need to find the time when bucket will be 60% of its full volume.
Let us first find 60% of its full volume:
If we assume that bucket will be 60% of its full volume after x seconds, we can set up an equation:
Therefore, it will take the bucket 1214 seconds to get to 60% of full.

The equation that can be ued to solve for the width of the rectangular frame is 2x² + 14x - 40 = 0.
<h3>What is the equation that can be used to solve for the width?</h3>
A rectangle is a 2-dimensional quadrilateral with four right angles.
Area of a rectangle = length x width
(2x + 4) x (2x + 10) = 120
Expand the brackets
4x² + 20x + 8x + 40 = 120
Add similar terms
4x² +28x + 40 = 120
4x² +28x - 80 = 0
Divide through by 2
2x² + 14x - 40 = 0

Ok so
If you are given the hypotenuse (pretend its 4), and you know that it is an isoceles right triangle, you know that the triangle is a 45-45-90 triangle (because you know that the angles = each other since the opposite sides are equal to each other). Since it is a 45-45-90 triangle, the legs will = A, and the hyp would equal to A root 2. you would put the hyp as 4 root 2. To find a you would divide the hyp by root 2. If you do that you can find that A is 4.
Hope this helps!
