13. If the following fractions were converted to decimals, which one would result in a repeating decimal? A. 3/4 B. 1/9 C. 5/11

Vladimir [108]

Hey there!

In order to find if a fraction would result in a repeating decimal, recall that a fraction is a division problem written vertically. All that you have to do is divide the numerator by the denominator. Also, remember that a repeating decimal will result in the same number after the decimal point as long as the calculator can handle.

3 ÷ 4 = 0.75

1 ÷ 9 = 0.11111111...

5 ÷ 11 = 0.45454545...

3 ÷ 0.42857143...

As you can see, two out of your four answer choices give you a repeating decimal. B gives you a repeated number of "1" while C gives you "45". D doesn't count since there is no pattern of repeated numbers that it follows.

Both B and C fall into the category of repeating decimal. If you're only able to choose one answer, I would ask your teacher, a parent, or a peer what they think.

Hope this helped you out! :-)

The probability that an event will occur is 2/3. which one of these best describes the likelihood of the event occurring?

Andrej [43]

Answer:

Step-by-step explanation:

Alright, lets get started.

The probability that an event will occur is 2/3.

Means out of 3 times, 2 times that event will occur.

Please refer the pie chart for this, blue is the color which represents event to be occur and orange is not to be occur.

We can see, blue part is much more than orange part.

means the likelihood of event occuring is LIKELY. : Answer

Hope it will help :)

Analyze the diagram below Need CORRECT ANSWER BELOW!!!

Zarrin [17]

Answer:

D. 8

Step-by-step explanation:

The given diagram is a trapezium. We know that the consective sides of a trapezium are equal. so,

Putting the values of consecutive sides equal:

So, KI will be equal to LI

3x-7 = x+3

$3x-7-x=x+3-x\\2x-7=3\\2x-7+7=3+7\\2x=10\\x=5$

Putting the value of x in the equation of KI

3x-7

=3(5)-7

=15-7

Hence, the correct answer is D. 8 ..
