Mars2501 [29]

Answer:

Option 4 - $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

$3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}$

Writing all number in one form,

$\frac{1}{5}=0.2$

$-\frac{1}{2}=-0.5$

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

$-1.4$

So, $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Therefore, option 4 is correct.

andriy [413]

Answer:

78,624,000 license plates

Step-by-step explanation:

For each of the 4 numbers, we have the following possibilities:

First number: 10 digits possible

Second number: 9 digits possible (one used)

Third number: 8 digits possible (two used)

Fourth number: 7 digits possible (three used)

For each of the 3 letters, we have the following possibilities:

First letter: 26 digits possible

Second letter: 25 digits possible (one used)

Third letter: 24 digits possible (two used)

The total number of license plates is the product of all these possibilities:

Number of plates = 10 * 9 * 8 * 7 * 26 * 25 * 24 = 78,624,000 license plates
