Let x =  time they take working together . Then:-

1/5 + 1/6 = 1/x

Multiply through by 30x:-

6x + 5x = 30
11x = 30
x = 30/11 = 2.73

Step-by-step explanation:

Given

L = 8cm

W = 12cm

r = 2 -- folded twice

Which of the follow if best describes AOR
Natali5045456 [20]

Answer:

C

Step-by-step explanation:

A major arc is an arc that is greater than 180 degrees.

A minor arc is an arc less than 180 degrees.

An acute angle is an angle less than 90 degrees.

A central angle is the angle created in the center of a circle with 2 sides being the radius.

<em>Thus, we can see in the figure that we are talking about the angle so we can eliminate major arc and minor arc.</em>

<em>Now, we clearly see that the angle is greater than 90 degree so it cannot be acute angle.</em>

<em />

The correct answer is central angle as it goes with the definition.
