You need school supplies. You go to the store and see that there are 6 different backpacks, 8 notebooks, 3 packets of pens, and

8 folders to choose from. You decide to go to another store to see their selection. The second store had a third of the backpacks, half the notebooks, and triple the number of pens. How many folders would the new store need to have in order for there to be the same number of combinations of items to choose from in the second store than in the first store?

Compute the total and annual return on the following investment Two years after paying 53500 for shares in a startup company you
wel

Answer:

-46.91%

Step-by-step explanation:

Given:

Cost of buying the shares = $53,500

Selling cost of the shares = $3,300

Number of years = 2

Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified

Now,

The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200

thus, the loss per year = \frac{\textup{50,200}}{\textup{2}} = -$25100

Hence,

Rate of return = \frac{\textup{Loss per year}}{\textup{Cost of buying}}\times100

or

Rate of return = \frac{\textup{-25100}}{\textup{53,500}}\times100

or

Rate of return = -46.91%

When baking a cake you can choose between a round pan with a 9 in. diameter and a 8 in. times 11 in. rectangular pan?
ivanzaharov [21]

Question says that there are two type of pans.

First pan has diameter of 9 inches.

Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.

It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.


Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches

Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.


Now surface area of second (rectangular) pan is given by formula of area of rectangle

Area = Length * width = 8*11= 88 square inches.
