is square root of 42 and rational or irrational

Answers

Answer 1
Answer: Irrational

The square root 42 cannot be written as a fraction, therefore it cannot be rational. more examples of irrational numbers include pi or let’s say square root of 2, 3, 10, etc… some random repeating decimals fall under irrational too.

Carolina and Patricia received their Christmas bonus and decided to use this weekend to buy their Christmas gifts .


Carolina decided to take advantage of the Great Winter Sale in Liverpool that offers discounts of 50% + 20%.

Patricia went to the mall and took advantage of the boutique discount that offers discounts of 70%.

They both bought 3 items with a total listing price of $120. At the end of their purchase rounds, they will have coffee with their friend Cristina and tell her about the offers they found. Based on their experiences, Cristina must decide where she will do her shopping.


Analyze this situation and think,


Where would you recommend Cristina to do her shopping? What is the final price paid on each establishment?

Applying what you have seen in your math classes, what where your calculations and how you can relate it to composition of functions.

Answers

Answer:

I would recommend Christina to do her shopping at any of those 2 places because they both have a discount of 70%. The final price paid on each establishment was $36.

120*0.7 = 84

120 - 84 = 36

Step-by-step explanation:

Carolina has a discount of 50%+20% which is the same as a discount of 70%, and Patricia had a discount of also 70%, so they both had the same discounts.

How many repeating digits are in the smallest group of repeating digits in the decimal equivalent of the fraction shown?




745/999

Answers

If x = 745/999, then

999x = 745

1000x - x = 745

This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.

To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then

1000x = y.yyy

1000x - x = y.yyy… - 0.yyy

999x = y

x = y/999

which means y = 745.

Answer:

3 digits

What integer is equivalent to 25 3/2

Answers

The number reads as 25 to the power of (3/2), which simplifies to

When an exponent is a fraction, the denominator of the fraction becomes the root. We can take the denominator of 2 and make it the square root, so the square root of

=
160.0781059

If this was intended to be 25^(3/2), then you can either apply the 3rd power or the second root first:

25^(3/2) = sqrt( 25^3 ) OR 25^(3/2) = ( sqrt(25) )^3

Personally, I’d go with the second approach, because I know sqrt(25) = 5 and I know 5^3 = 125

You could do sqrt( 25^3 ) = sqrt( 15625 ), but I don’t know that value without a calculator.
(A calculator will confirm sqrt ( 15625 ) = 125
