Hope this helps !!!!!!!!!!!!
There are 50 tables.
20 tables seat two people and 30 tables seat 4 people.
Let y = 4x
x = 1/4 y
f(-1)x = 1/4 x = h(x)
Its D
3 over 50
= 3/50 Multiply top and bottom by 2
= (3/50)*(2/2) = 6/100
= 0.06
<h3>The exact circumference of a circle with a radius of 17 mm is

or 106.76 mm</h3>
<em><u>Solution:</u></em>
Given that,
A circle with radius 17 mm
To find: circumference of circle
<em><u>The circumference of circle is given as:</u></em>

Where, "r" is the radius of circle
<em><u>Substitute r = 17 mm</u></em>

Thus the exact circumference of a circle with a radius of 17 mm is
or 106.76 mm
