F is inversely proportional to d 2 . When F = 3 , d = 4 Work out F when d = 2

Mathematics

Answer:

F = 6

Step-by-step explanation:

When something is inversely proportional to another thing, when one of the numbers increases or gets multiplied by a constant, the other number decreases or gets divided by a constant.

In this scenario, when F = 3, d = 4.

When d = 2, we are dividing the earlier value of 4 by 2. Now, since F is inversely proportional to d, we have to multiply the value of F by 2 to get what F equals when d = 2. 3 times 2 is 6, so F = 6 when d = 2.

The length of a rectangle is 6 in longer than its width.if the perimeter of the rectangle is 68in find the length and width ?
wel

The length and the width of the rectangle are 20 and 14 inches respectively

<h3>How to find the length and width?</h3>

The given parameters are:

Length = 6 + Width

Perimeter = 68 inches

The perimeter of a rectangle is calculated as:

Perimeter = 2 * (Length + Width)

So, we have:

2 * (Length + Width) = 68

Divide both sides by 2

Length + Width = 34

Substitute Length = 6 + Width in Length + Width = 34

6 + Width + Width = 34

Evaluate the like terms

2 * Width = 28

Divide both sides by 2

Width = 14

Substitute Width = 14 in Length = 6 + Width

Length = 6 + 14

Evaluate

Length = 20

Hence, the length and the width of the rectangle are 20 and 14 inches respectively
