Answer:
Step-by-step explanation:
Let us assume that the total area of the wall to be painted is w.
Then Jason painted an area of (1/4)w on Monday
And he painted (2)(1/4)w on Tuesday
So to find the unpainted area, we just take the whole wall area to be painted (which is w) and subtract out the amounts painted on Monday and Tuesday, which are shown above.
So the unpainted area (U) would be shown by the following expression:
U = w - (1/4)w - (2)(1/4)w
We can simplify this expression by factoring out w
U = w(1 - 1/4 - 1/2)
U = w (1/4) or w/4
So all Jason needs to do is paint as much of the wall as he did on Monday, and he will be done!
Answer:
A circle!
Step-by-step explanation:
Typically, for most 3 dimensional shapes, cutting parallel to the base will result in the shape that the base takes on. Because the base of a cylinder is a circle, the shape of a cross-section parallel to the base of a cylinder would be a circle.
Sin x = cos (90-x)
90-x = 19
x = 71
The answer is 71 degrees.
