Is √6/8. rational or irrational?

Ipatiy [6.2K]

<h2>Answer:</h2>

The number is irrational.

<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>

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

-------------------------------------------------------------------------------------------------------

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

A health club sold ten memberships in one week for total of $3000. If male memberships cost $300 and female memberships cost $30

Ket [755]

Answer:

Step-by-step explanation:

The reason you haven't gotten an answer to this is because in its current formatting, there is no answer. Here's what I mean:

The first equation is going to be concerning the NUMBER of memberships sold, where m is male and f is female. The total number of memberships was 10:

m + f = 10

Now for the money equation. The total amount of money made from that number of memberships was 3000, where male memberships cost $300 and so do the female memberships, giving us an equation of

300m + 300f = 3000

Go back to the first equation and solve for either m or f. I solved for m in terms of f:

m = 10 - f and sub that into the second equation for m to get:

300(10 - f) + 300f = 3000 and

3000 - 300f + 300f = 3000. Here is where you find the problem. The -300f and the 300f cancel each other out, leaving you with the fact that

3000 = 3000 which it does, but it doesn't give us any viable answer.

I would have to say that since we can't do math on this, that the most credible answer you'll find is that the same number of male and female memberships were sold because 5 male memberships cost $1500 (5 memberships at $300 a piece is $1500) and 5 female memberships also cost $1500.

1500 + 1500 = 3000

Jada bought $53 worth of snacks. She used a 10% off coupon. She then paid 8% tax on the original amount. What is the total she p

Montano1993 [528]

Answer:

The amount which Jada paid after discount and tax is $ 51.64

Step-by-step explanation:

Given as :

The original price of snacks = $ 53

The price of snacks after applying 10% off coupon = 53 - 10% of 53

Or , The price of snacks after applying 10% off coupon = 53 ( $\frac{100-10}{100}$ )

or, The price of snacks after applying 10% off coupon = 53 × 0.9 = $ 47.7

Now the tax applied on the original amount = 8 % of $ 53

or, the tax applied on the original amount = $\frac{8}{100}$ × 53

or, , the tax applied on the original amount = $\frac{424}{100}$ =$ 4.24

So The total paid amount = $ 47.4 + $ 4.24 = $ 51.64

Hence The amount which Jada paid after discount and tax is $ 51.64 Answer
