Multiply 3/6 x 3/6 and then reduce

Answer: \dfrac{1}{4}

Step-by-step explanation:

Given : John rolls a six-sided number cube twice.

Total number of outcomes on a fair cube = 6

When we roll two dices , then the total number of outcomes :-

6\times6=36

Number of favorable outcomes of getting an even number and then an odd number :-

3\times3=9   [since there are 3 odd and 3 even numbers on it]

Now, the probability of getting an even number and then an odd number =

\dfrac{9}{36}=\dfrac{1}{4}

Eddi Din [679]

Answer: 3/25 and 9/20

Step-by-step explanation:

We take the number and covert it into a fraction

A 2 digit Numerator = a 3 digit denominator

A 3 digit Numerator = a 4 digit denominator

And so on...

Then We can reduce,

45/100 = 9/20

120/1000 = 3/25

Hope this helped!

Question 27 <br> Find the length of the hypotenuse. Leave answer in simplest radical form.
skelet666 [1.2K]

Use SOHCAHTOA.  Since we are looking for the hypotenuse, you must use sine or cosine.  Since, we are given the adjacent side, use cosine.

cosx=a/h

cos45=8/h

√2/2=8/h

<em>*Cross multiply*</em>

h√2=16

<em>*Divide both sides by √2*</em>

h=16/√2

<em>*Multiply by √2/√2*</em>

h=(16√2)/2

<em>*Simplify the fraction*</em>

h=8√2

Hope this helps!!
