<u>Answer:</u>

quotient = 7

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

We are asked to evaluate the following expression:

4\frac{2}{3} \div \frac{2}{3}

• To solve this we can first convert the mixed number 4\frac{2}{3}  into an improper fraction:

4\frac{2}{3}  ⇒  \frac{14}{3}

• Next, we know that dividing by a fraction is the same as multiplying by its reciprocal (the reciprocal of a fraction is what is you get by swapping the numerator and denominator):

reciprocal of \frac{2}{3} = \frac{3}{2}.

• Therefore, the expression now becomes:

4\frac{2}{3} \div \frac{2}{3}

⇒ \frac {14}{3} \div \frac {2}{3}

⇒  \frac {14}{3} \times \frac {3}{2}

⇒ 7

Answer:

  • 39.7%

Explanation:

<u />

<u>1. First find the density of your chain</u>

  • Density = mass / volume

  • Volume = displaced water volume

                      = Volume of Final level of water - initial level of water

                     = 20 ml - 15 ml = 5 ml

  • Mass = 66.7 g

  • Density = 66.7g / 5 ml = 13.34 g/ml

<u />

<u>2. Second, write the denisty of the chain as the weighted average of the densities of the other metals:</u>

Mass of gold × density of gold + mass of other metals × density of other metals, all divided by the mass of the chain.

Calling x the amount of gold, then the amount of other metals is 66.7 - x:

        \dfrac{19.3\cdot x+9.7\cdot (66.7-x)}{66.7}=13.34

       19.3x+635.66-9.7x=889.778

      9.6x=254.118\\\\x=26.47

Then, there are 26.47 grams of gold in 66.7 grams of chain, which yields a percentage of:

  • (26.47 / 66.7) × 100 = 39.7%

Pythagorean triples are given by the formulas x2 - y2, 2xy, and x2 + y2. Use the formulas for the Pythagorean triples to prove w
Arte-miy333 [17]
Let k be an integer. Suppose there is a triangle with legs of length 16 and 2k+1. Then by the Pythagorean theorem, the length of the hypotenuse should be

\sqrt{16^2+(2k+1)^2}=\sqrt{4k^2+4k+257}

The formulas for Pythagorean triples say that if the legs are integers, then so must be the hypotenuse, because if x=16 and y=2k+1 are integers, then so are x^2-y^2, 2xy, and x^2+y^2.

However, 4k^2+4k+257 is not a perfect square trinomial, which means for any integer k, the length of the hypotenuse is not an integer, so such a triangle doesn't exist.
