So, the first thing we need to know is what is what.


So,  A natural number is a whole number

A whole number is an integer

and An integer is a rational number.


Now, since there is a terminating decimal (a decimal that does not go on forever) we know it is a rational number.


Since there is a decimal, it cannot be an integer, therefore

It is a rational number

Is 2.5 greater or less than 1,950
OverLord2011 [107]

Answer:

2.5 is less than 1,950.

Step-by-step explanation:

The decimal place is at the end of 1,950.

The decimal place is in the middle of the 2 and the 5.

Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.

You can subtract both values.

1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.

0 < 1,947.50.

Therefore, 2.5 < 1,950

Part A is already answered <br><br> Part B asks: What is the length of the hypotenuse?
xxTIMURxx [149]

Answer:

52

Step-by-step explanation:

Using the Pythagorean theorem

a^2+b^2 = c^2

20^2 + 48^2 = c^2

400 +2304=c^2

2704=c^2

Taking the square root of each side

sqrt(2704) = sqrt(c^2)

52 = c
