irrational

rational

irrational

rational

Step-by-step explanation:

the first answer here is wrong and does not fit to the problem with 5 expressions.

13/90 is rational per definition (a ratio of two natural or integer numbers).

sqrt(84) is therefore irrational.

4/11 is per definition rational.

12×pi is irrational, because pi is irrational.

4.6363636363... is rational, because it is 51/11

16 hours

Step-by-step explanation:

Multiply the 4/5 by 4 to get the denominator as 20. So you do 4 x 4 which equals 16 and 5 x 4 which equals 20 so you get 16/20 miles or 16 hours.

Find the value of x that makes ABCD a parallelogram.
olganol [36]

The angle 5x will be 50⁰. Then the correct option is D.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The diagram is given below.

We know the sum of internal angles is 360 degrees.

Then we have

5x + 130 + 5x + 130 = 360

                         10x = 100

                             x = 10

Then the angle 5x will be

5x = 5(10)

5x = 50⁰

Then the correct option is D.

More about the parallelogram link is given below.
