Answer:
About 1 gal
Step-by-step explanation:
When you are estimating with fractions, you should round them off to the closest integers that you can work with in your head.
⅓, ⅕, and ½ are all close to zero, but that's absurd, because Neil clearly has some paint
.
Instead, let's estimate that ⅓ gal + ⅕ gal make about ½ gal.
They still have the other ½ gal, and
½ gal + ½ gal = 1 gal.
Neil has about 1 gal of paint.
Answer:You get 21 Square inches i believe
Step-by-step explanation:
For the given function, we have:
Domain: (-∞, ∞)
Range: [-2, ∞)
<h3>
</h3><h3>
How to find the domain and range of the given function?</h3>
Remember that for a function the domain is the set of the possible inputs while the range is the set of the outputs.
On the graph, we can see a quadratic equation, remember that for every polynomial the domain is the set of all the real values, the same is for this case, so we conclude that the domain is:
D: (-∞, ∞)
The range will be the set of all values larger than the minimum of the parabola, which is at the vertex.
On the graph, we can see that the minimum is y = -2, then the range is:
R: [-2, ∞)

Problem 4
x = interior angle
y = exterior angle
x = 3y since "each interior angle...is three times the measure of each exterior angle"
The interior and exterior angles are supplementary, meaning,
x+y = 180
3y+y = 180
4y = 180
y = 180/4
y = 45
So we know that
n = 360/y
n = 360/45
n = 8
You are correct in saying that this is an octagon
===========================================================================================
Problem 5
x = measure of missing angles
Find the sum of the interior angles
S = 180*(n-2)
S = 180*(5-2)
S = 540
The five interior angles add up to 540 degrees
Add up the five angles, set equal to 540, then solve for x
90+90+90+x+x = 540
2x+270 = 540
2x+270-270 = 540-270
2x = 270
2x/2 = 270/2
x = 135
So you have the correct answer of choice C) 135 degrees
===========================================================================================
Problem 6
S = 180*(n-2)
S = 180*(6-2)
S = 180*4
S = 720
You have the correct answer. Nice work on all three correct answers.
