Is √6/8. rational or irrational?
Ipatiy [6.2K]
<h2>Answer:</h2>

<em>The number is </em><u><em>irrational</em></u><em>.</em>

<h2>Step-by-step explanation:</h2>

<h3>1. Convert to decimal.</h3>

\sqrt{\frac{6}{8} } =\sqrt{0.75} =0.8660254038...

<h3>2. Conclude.</h3>

<em>Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is </em><u><em>irrational</em></u><em>.</em>

<u><em>-------------------------------------------------------------------------------------------------------</em></u>

<em>Note.</em><em> In case the number expressed in the question was </em>\frac{\sqrt{6} }{8}, the answer  would still be <u><em>irrational</em></u><em>, for the same reasons explained above</em>.

As we h ave the first quiz score provided, we would need to find the score for the second quiz.

We will do this by dividing the questions answered correctly to the total number of questions on the quiz.

Let's begin.

27/30 = 90

Now, we know that she received a grade of 90 percent on the second quiz.

<u>Therefore, she performed better on the social studies quiz. </u>

How many different sums of money can be formed from penny and half a dollar?
mel-nik [20]
So its a penny and a half dollar that will give you $0.51 so you can do this
starting with your 51 pennies you can get rid of every 5 pennies and replace them with a nickel so say you get rid of 10 pennies you would have 2 nickels
so 51/5= 10.2
or 10 nickels
so that is ten combos right there along side 51 pennies
so no you do the dimes witch for every 10 pennies you get rid of is = to 1 dime so 51/10=5.1 or 5 dimes so that gives you 5 more combos
so now its 1 penny combo with 10 nickel combos with 5 dime combos
now for quarters for every 25 pennies you get rid of is = to 1 quarter so
51/25=2.04 or just 2 and with half dollars ( they do make thoses ) it is for every 50 pennies you get rid of is = to one half dollar ( which is 50 cents) so 51/50= 1.02 or 1 so it is
1 penny combo + 10 nickels combos + 5 dime combos + 2 quarter combos + 1 half dollar combo =
1+10+5+2+1=19 different sums of money

How far are Gustavo and Aiden away from each other
allsm [11]

Answer: Gustavo is 261.96 meters away from Aiden. Or Aiden is 261.96 meters away from Gustavo.

Step-by-step explanation: From the question, considering a North, East, South and west pole, Gustavo ran 23° above the east horizontal, while Aiden ran 33° below the east horizontal.

             Therefore, Where a and b are distances travelled respectively by Gustavo and Aiden. While θ is the angle between them.the total angle between them is 23 + 33 = 56°.  Therefore, let the distance between them be c and we can calculate that using the cosine law.c² = a² + b² – 2ab cos θ. Therefore, let the distance between them be c and we can calculate that using the cosine law.c² = a² + b² – 2ab cos θ.

Therefore, they are 261.96 meters apart.

c² = 300² + 250²– 2(300) (250)cos 56

c² = 90000 + 62500 - 83878.9355

c² = 68621.0645

c = √68621.0645

c = 261.96 m
