What is u = kx + ух, for x
Ivahew [28]

Answer:

<h2>x=  \frac{u}{k + y}</h2>

Step-by-step explanation:

u = kx + ух

First of all factorize x out at the right side of the equation

That's

u = x(k + y)

Divide both sides by ( k + y) to make x stand alone

That's

<h3>\frac{x(k + y)}{k + y}  =  \frac{u}{k + y}</h3>

We have the final answer as

<h3>x =  \frac{u}{k + y}</h3>

Hope this helps you

A jewelry designer is making a pendant. The pendant will be a circular dis (center O) with a circular hold cut out of it, as sho
antoniya [11.8K]

Answer:

2884.8 millimeters squared

Step-by-step explanation:

Given:

The radius of the disc is 35 millimeters, so the area of it is:

πr^{2} = 3.14*35^{2} = 3846.5

Then, we find out the area of the circular hold cut out of the bigger one, its radius is a haft of the radius of the bigger circle = 35/2 = 17.5

πr^{2} = 3.14*17.5^{2} =961.6

=>  the area of the pendant = 3846.5  - 961.6  =2884.8 millimeters squared

The length of a rectangle is 16 inches. if the width is 25% of its length, what is the perimeter of the rectangle​
Leokris [45]

Answer:

Perimeter = 40 inches

Step-by-step explanation:

Length = 16 inches

Width = 25% of length (16)

          = 25% of 16

25% = 1/4

Width = 1/4 x 16

          = 4 inches

Length = 16 inches

Width = 4 inches

Perimeter of a rectangle = length + length + width + width:

                                         = 16 + 16 + 4 + 4

                                         = 32 + 8

                                         = 40

PERIMETER = 40 inches

So glad I could help :)
