If Delta and United just arrived at the airport when will the next to arrive at the airport at the same time

Answers

Alright so if Delta comes every 4 minutes and United arrives every 6 minutes, the time would be 12 minutes when they would arrive at that the same time because, 4 times 3 = 12 and 6 times 2 = 12 so you must find out the least common multiple to do so. I hoped that helped in an sense.

What is the average number of minutes each month during a leap year? Please show your work.

Answers

To find the number of minutes in each month, first find the number of days in a leap year. There are 366 days in a leap year, and 24 hours each day. 366 times 24 will give you the number of hours each leap year. There are 8784 hours in a leap year. To find the minutes, you need to multiply this number by 60, because there are 60 minutes in an hour. When you solve this, you'll get the answer, there are 527040 minutes in a leap year.

You work part-time at the “Pack-it and Mail-it” that sells containers used for shipping items. Your photography teacher asks you to recommend the best package to ship 35 mm film containers. The film containers are 1 inch in diameter and 2 inches in height, and they are to be shipped in groups of twelve.A) Find the volume of twelve film containers. Round your result to two decimal places and show all calculations below.

B) Which container should be used to fit a dozen film containers with the least amount of wasted space? Explain your reasoning.

At work you get a list of package sizes. Your store has four box sizes that look like they might work. The sizes are given in the form l x w x h. They are 3 in. x 2 in. x 5 in., 4 in. x 3in. x 2 in., 5 in. x 6 in. x 5 in., and 3 in. x 2 in. x 3 in.

Answers

Answer:

(a)18.85 Cubic Inches

(b)The box with dimensions of 4 in. x 3in. x 2 in.

Step-by-step explanation:

Part A

Volume of the 12 Containers

Height =2 Inches

Diameter=1 Inch

Radius=Diameter/2=1/2=0.5 Inch

Volume of a cylinder=\pi r^2 h

Volume of the 12 Containers

=12 X \pi r^2 h\n=12 X\pi X0.5^2X2\n=6\pi $ cubic inches\n=18.85 \text{cubic inches (to two decimal places)}

Part B

To determine the container which should be used, we first determine the volume of the available boxes.

Volume of the boxes

Volume of box with dimension 3 in. x 2 in. x 5 in.=3X2X5=30 Cubic Inches

Volume of box with dimension 4 in. x 3in. x 2 in.=4X3X2=24 Cubic Inches

Volume of box with dimension 5 in. x 6 in. x 5 in.=5X6X5=150 Cubic Inches

Volume of box with dimension 3 in. x 2 in. x 3 in. =3X2X3=18 Cubic Inches

The box that should be used with the least amount of wasted space is he box with volume 24 Cubic inches. i.e. box with dimensions 4 in. x 3in. x 2 in.

This is because the volume of the box(18 cubic inches) with dimension 3 in. x 2 in. x 3 in. is less than what is required.
