What is the sum of 1/9, 2/3, and 5/18?<br> A. 19/18<br> B.4/15<br> C. 12/9<br> D. 8/20
kari74 [83]

Answer:

19/18

Step-by-step explanation:

The GCF of 9, 3, and 18 is 18.

Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.

9 * 2 = 18

1 * 2 = 2

2/18

3 * 6 = 18

6 * 2 = 12

12/18

5/18

Add all three fractions together:

12/18 + 5/18 + 2/18 = 19/18

SUPER HARD QUESTION (I POSTED THE DIAGRAM) In the diagram of.....
Kisachek [45]

Answer:

A

Step-by-step explanation:

Since m∠JOK is 1/5th of the measure of the full circle (we know this because 72° is 1/5th of 360° and 360° is the measure of the whole circle), we know that the measure of minor arc JK will be 1/5th of the circumference of the circle. C = 2πr and we know that r = 5 so the circumference is 10π. 1/5th of that is 2π.

How many three letter permutations can be formed from the first five letters of the alphabet?
Vsevolod [243]

Answer:

There are 60 permutations that can be formed from the first five letters of the alphabet.

Step-by-step explanation:

The number of three letter permutations that can be formed from the first five letters of the alphabet is 5P_{3}.

5P_{3} =\frac{5!}{(5-3)!}

=\frac{5!}{2!}

= 60

Hence, there are 60 permutations that can be formed from the first five letters of the alphabet.
