The value written as 2/7 is a rational number and the other options are irrational numbers.

<h3>What is a rational number?</h3>

A rational number is a number that does not end in a non terminating decimal. Surd forms as well as the value pi are all irrational numbers. We must note that the option that has no surd form or pi as a denominator is a rational number.

Hence; the value written as 2/7 is a rational number and the other options are irrational numbers.

Using the relation between velocity, distance and time, it is found that the commute took 48 minutes.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is distance divided by time, that is:

v = \frac{d}{t}

For Lena, we have that d = 29, v = 36, hence the time in hours is given by:

t = \frac{d}{v} = \frac{29}{36} = 0.8056

In minutes, the time is given by:

tM = 0.8056 x 60 = 48.

I’m not quite sure how to answer this question.
Marina CMI [18]

When two shapes are mathematically similar, that means that all their sides are in a proportion.

We know the sieds of EH and AD, and so we can find the proportion of the shapes using these two sides.

EH/AD = 6/9 = 2/3

The ratio of EFGH to ABCD is 2:3

Now we have to find BC.

Becuase they're in proportion, we can form this equation:

\frac{8}{BC} = \frac{2}{3}

Cross multiply:

24 = 2*BC

Divide both sides by 2:

BC = 12 cm

Good luck!

C. -X to the 3rd power, 4x to the second power and 5x all share the common factor or X, therefore you put it outside the parenthesis. What you have left is -X to the second power minus 4x minus 5.
