Answer:

Answer is 25ft.

Step-by-step explanation:

l=20ft.

h=16ft.

let 'w' be x.

then

l=√w2+h2

or l=√x2+(16)2

squareing on both side.

or (20)2=√(x+16)2

or 400=x+16

or x=400/16

or x=25.

so that the value of W is 25ft.

If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like

Serjik [45]

The measuring unit is the standard unit of a quantity

The measuring unit of size 0.001 is represented by one millionth circle

<h3>How to determine the unit of base 0.001</h3>

The basic measuring unit in base 7 is given as:

49 circles

The above can be represented as:

Base 7 = 49 circles

Represent the base with n.

So, we have the following rule

$Circle = n^2$

For measuring unit 0.001, we have:

$Circle = 0.001^2$

Evaluate the square

$Circle = 0.000001$

This means that,

The measuring unit of size 0.001 is represented by one millionth circle
