Wind is air in motion. Two factors are necessary to specify wind, speed and direction. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Because of the way Earth rotates, solar light rays heat some parts of Earth's surface more than others. Air at hot spots rises and expands, leaving low pressure beneath it. Air at cold areas cools and falls, creating high pressure. When high-pressure air rushes into a low pressure area, that rush of air is wind.

Eric is designing a logo for his company. The logo is a rectangle with a length twice as long as the width. The logo is designed

Vladimir79 [104]

Answer:

The width of the logo need to be 15 cm.

Step-by-step explanation:

Since the logo is a rectangle, it's area is given by the product of the width and the length.

Area = width*length

Since the width is an unkown value we will call it "x" and the length is twice the width so it'll be "2*x". The area of the logo is:

Area = x*(2*x) = 2*x²

In order to have a patch that is 450 cm² we need:

2*x² = 450

x² = 450/2 = 225

x = sqrt(225) = 15 cm

The width of the logo need to be 15 cm.

The plot below shows the volume of paint left in 444 cans.

yKpoI14uk [10]

The amount of paint that would be contained in each of the can would be 8.

<h3>How to solve for the amount of paint.</h3>

Using the information in the question we have the following

We have to solve the equation as

(2 1/2) + 2(4) + 1(5 1/2) =

2.5 + 8 + 5.5

= 16

Each of these would have to hold 16/2 = 8 pints.
