Answer: 14 1/8

Step-by-step explanation: To add mixed numbers, first add the fractions. In this case, we have two fractions \frac{1}{2} and \frac{5}{8} and these fractions have unlike denominators. We need to find a common denominator for both of these fractions to be able to add.

<u>Least Common Denominator:</u>

\frac{1}{2} = \frac{4}{8}

\frac{5}{8} = \frac{5}{8}

12 4/8 + 1 5/8 = 13 9/8

Notice that 9/8 is an improper fraction so we can change it to a mixed number.

9/8 = 1 1/8

13 + 1 and 1/8 = 14 1/8

A polygon with side lengths of 6, 9, and 15 forms a triangle. <br> True <br> False
Butoxors [25]

Try this: Combine 6 and 9, obtaining 15.

Compare this sum, 15, to the length of the 3rd side: 15.


If placed end to end, the 2 sides with lengths 6 and 9 form a new line of length 15. We'd end up with this new line superimposed on the 3rd side (with length 15).


Think: Do 2 straight lines of length 15, superimposed on one another, form a triangle?

The formula for the circumference of a circle is c=rd, where d is the length of the diameter. If d is a rational number, what ca
dimaraw [331]

Answer: The answer is (d) It is an irrational number.

 

Step-by-step explanation:  Given formula for circumference of a circle is

\textup{c}=\textup{r d},

where 'd' is the length of the diameter and a rational number.

We are to choose one of the given four options for the circumference 'c' of the circle.

We know that the circumference of a circle with diameter 'd' is given by

\textup{c}=\pi \textup{d},

Comparing this with the given equation, we get

r=\pi,~\textup{where}~\pi~\textup{is an irrational number}=\dfrac{22}{7}.

Now, the product of a rational and an irrational number is again irrational, so 'r × d' will be an irrational number.

Hence, the circumference, c = rd is irrational.

Thus, the correct option is (d) It is an irrational number.
