Step-by-step explanation:

$given \\ (x + \frac{1}{x} ) = 7 \\ now \\ (x + \frac{1}{x} ) ^{2} \\ (7) ^{2} (given) \\ 49 \\ again \\ {x}^{2} + ( \frac{1}{x} ) ^{2} \\ (x + \frac{1}{x}) ^{2} - 2 \times x \times \frac{1}{x} \\ (7) ^{2} - 2 \\ 49 - 2 \\ 47$

A Ferries wheel had a radius of 58 feet. What is the distance a passenger will travel one time around the Ferries wheel?

topjm [15]

Answer:

364.42 ft.

Step-by-step explanation:

For step 1 we should multiply pi by r and 2.

π x r x 2

For step 2 we should multiply pi by 58 and 2.

π x 58 x 2

In result, we should end up with 364.424748 ft. or for short 364.42 ft.

I hope I helped you... Have a great and nice day! :D

xenn [34]

Cross multiply
3(2x + 1) = 5(2x - 5)
expand by using distributive property
6x + 3 = 10x - 25
-4x = - 28
x = 7

1 inch : 12feet. if the actual width of the tent is 36 feet how wide is the tent.

Murljashka [212]

Answer:

If the actual width is 36 feet, then the tent is 3 inches wide in scale.

Step-by-step explanation:

Let x be the width in inches.

The scale is: 1 inch : 12feet. The scale can be represented as inches to feet ratio and then equivalent ratios will be used

This can be expressed as fraction as 1/12

The equivalent ratios are:

$\frac{1}{12} = \frac{x}{36}\\\frac{36}{12} = x\\x = 3$

Hence,

If the actual width is 36 feet, then the tent is 3 inches wide in scale.
