Find the volume of each size stack by multiplying Length x width x height.

Once you have the volume for the 3 different stacks of books, add the together.

Bottom: 12 x 1 x 6 = 72 cubic inches per book x 2 = 144 cubic inches total.

Middle: 10 x 1 x 5 = 50 cubic inches per book x 2 = 100 cubic inches total.

Top: 7 x 0.5 x 4 = 14 cubic inches per book x 2 = 28 cubic inches total.

Total volume = 144 + 100 + 28 = 272 cubic inches.

marysya [2.9K]
SO, first you divide the numerator by the denominator. 

Then write it like this: \frac{88}{12}=  \frac{13 +3.25}{25} = 3 \frac{13}{25}.

A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Comp
Stells [14]

Answer:

(1)raise, (2)decrease

Step-by-step explanation:

A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Compared with the condition before the increase in marginal costs, the monopolist will <u>raise</u> its price and <u>decrease</u> its level of production.

Marginal cost is the additional cost incurred when one more unit of the output is produced. It is a J-shaped curve, which <em>initially decreases, reaches its minimum and then starts increasing.</em>

Marginal cost is an important factor in economic theory because a company that is looking to maximize its profits will produce up to the point where <em>marginal cost (MC) equals marginal revenue</em>

A square is put together by two triangles. The hypotenuse is 11 cm and width of 8 cm. find the height of triangle?
Aleks [24]
You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this:
8^2 + b^2 = 11^2

Square 8 and 11. 
64 + b^2 = 121

Subtract 64 from 121
121 - 64 = 57

The new equation is:
b^2 = 57

Now take the square root of both sides to get b by itself. 
b = about 7.5

Answer: The height of the triangle is 7.5

there are 6 flavors of candy in a bag strawberry lime lemon cherry or grape what is the probabilty of selecting blueberry
Furkat [3]

Number of strawberry = 1

Number of Lime = 1

Number of Lemon = 1

Number of Cherry = 1

Number of Blueberry = 1

Total number of candies = 1 +1 + 1 +1 +1 +1 =6

favourable outcome = 1

P(of selecting blueberry ) = \frac{Number of Blueberry }{Total number of candies}

P(of selecting blueberry) = \frac{1}{6}

P(of selecting blueberry) = 0.1666

P(of selecting blueberry) = 0.17
