In 2010, Americans generated 250 million tons of garbage. There are about 2,000 landfills in the United States. Assuming that each landfill is the same size and that trash is divided equally among them, determine how many tons of garbage were sent to each landfill in 2010.

Answers

Answer

125,000 tons of garbage per landfill

Step-by-step explanation:

250 million total tons of garbage was sent to 2,000 landfills. Since it is assumed each landfill gets an equal amount of garbage, we can easily divide.

250,000,000 / 2,000 = 125,000 tons of garbage per landfill

henceforth, each landfill received 125,000 tons of garbage

Mrs. Hernandez earns $35.60 per hour and in one week earned $854.40. For how many hours did she work last week? What expression matches A: 8,544 divided by 356 B: 85,440 divided by 356 C. 8,560 divided by 544

Answers

Answer:

Option A

Step-by-step explanation:

Given the following question:
Mrs. Hernandez earns $35.60 an hour
One week she earned $854.40

To find the answer we divide 8,544 by 356

[tex]8544\div356=24[/tex]
[tex]854.40\div35.60=24[/tex]

Mrs. Hernandez worked "24 hours last week" by using the first options equation, we can find that answer.

Answers

Answer:

1. FH, 2. GH,  3.IH  4. GI,  5. FG

Step-by-step explanation:

According to a certain geometric theorem, the smallest angle is always opposite to the smallest side of a triangle. Likewise, the largest angle is always opposite to the largest side. Using this theorem we can properly order the angles and sides.

Additionally, the interior degrees of a triangle will always be 180, and the interior of this quadrilateral is 360 degrees. Using this we can determine the missing angles.

180 - 75 - 55 = 50 (first missing angle)

180 - 59 - 63 = 58 (second missing angle)

The smallest angle would be 50 degrees and the largest 75.

The second smallest is 55 degrees, the third smallest is 58 degrees, the fourth smallest is 59 degrees, and the fifth is 63 degrees.

Now, one thing that seems a bit confusing is the fact that GH is opposite to 2 different angles, so how do we know WHICH angle to use to find its length. From what I understand, we should be able to find the average of the two angles across from this side to see what its place would be in terms of length.

63 + 50 = 56.5

This would make side  GH larger than FH but less than HI

This is how I would solve the problem, and I think this is the correct order. Please let me know whether it turns out right.

Mark the formula/theorem below

The angle measures bigger means the opposite side of angle is bigger.

Here

55<59<63<75

So the order is

FH<IH<GI<GH<FG

A recycling bin is in the shape of a rectangular box. Find the height of the box if its length is 15 ft its width is 10 ft, and its surface area is 600 ft². (In the figure, h=height. Assume that the given surface area includes that of the top lid of the box.)​

Answers

Answer:

The surface area of a rectangular box is the sum of the areas of the flat rectangular faces of the box. The height is the vertical side of the box.  So the other sides are the length and width.  Try to picture a box in your head, or you can draw it on paper.

Let x = length

Let y = width

Let h = height

Using these variables, we can write an equation that represents the surface formula.

A = 2(area of bottom face) + 2(area of front face) + 2(area of side face)

A = 2xy + 2xh + 2yh

This is general equation for surface area.  All we need to do is plug in the known values into it and solve for h.

496 = 2(18)(8) + 2(18)h + 2(8)h

496 = 288 + 36h + 16h

Now it comes down to simple algebra.  Isolate the h terms and solve for h from there.

208 = 52h

Divide both sides of the equation by 52 to get your height.  I let you finish up here.

Answer:

  a)  21, 34.5, 54.75, 85.125

Step-by-step explanation:

All of the answer choices differ in the first term, so that is the only one you need to figure here. However, we will do them all, so you can see it done.

We note that x > 0 for all of the values of x that we need to use. That means the recursive relation is the one we're using for computation.

f(1) = 3/2·f(0) +3 = (3/2)(12) + 3 = 18 +3 = 21 . . . . . . matches choice (a)

f(2) = 3/2·f(1) +3 = (3/2)(21) +3 = 63/2 +3 = 69/2 = 34.5

f(3) = 3/2·f(2) +3 = (3/2)(34.5) +3 = 51.75 +3 = 54.75

f(4) = 3/2·f(3) +3 = (3/2)(54.75) +3 = 82.125 +3 = 85.125

When you're computing for sequential input values, each depends on the previous value you computed.

What is a a marginal cost?

Marginal cost simply means the change in production cost due to an additional unit produced.

From the complete question, the cost function is given as 60 - 40e^-t. Therefore, the marginal cost will be:

C'(t) = d/dt (60 - 40e^-t)

= d/dt (60) - 40 d/dt (etc)

= 0 - 40(-1)e^-t

= 40 e^-t.
