Answer:

a. The number of custom necklaces that can be manufactured if each requires 2 7/8 ounces of gold is 74 necklaces.

b. The value of the gold in each necklace is $1761

Step-by-step explanation:

(a) Number of necklaces

27/8 ounces of gold=2.875

No of necklaces=212.75oz x 1 necklaces/2.875oz

                          =74 necklaces

(b)Value of gold in each necklace

There are 2.875 oz of 14K gold in each necklace. Pure gold is 24K.

Mass of pure gold=2.875oz x 14k/24k

                              =1.677083oz

Pure 24K gold is worth $1050/oz.

Value of pure gold=1.677oz x 1050/1oz

                              = 1760.9 dollars

The value of the gold in each necklace is $1761

a) Number of custom necklaces that can be crafted if each requires 2 7/8 ounces of gold which is 74 necklaces.

b) The gold value of each necklace is $1761

  • Algebra is a branch of mathematics that deals with symbols and the rules for using those symbols.  

  • In elementary algebra, these symbols (now written in Latin and Greek letters) represent quantities with no fixed value, called variables.  

(a) Number of necklaces

2 7/8 ounces of gold = 2.875

Number of necklaces = 212.75 oz x 1 necklace / 2,875 oz

= 74 necklaces

(b) Gold value in each necklace

There is 2,875 oz of 14k gold in each necklace. Pure gold is 24K.

Mass of pure gold = 2,875 oz x 14k / 24k

= 1.677083oz

Pure 24-karat gold is worth $1,050 per ounce.

Pure Gold Value = 1,677 oz x 1050/1 oz

= $1760.9

The gold value of each necklace is $1761

What is the product of 4 x 2/3
Genrish500 [490]

Answer:

Step-by-step explanation:

Remark

A good thing to understand is that when a whole number and a fraction are multiplied, the method is the same as multiplying 2 fractions. What that means is make the whole number into the numerator of a fraction and put a 1 where the denominator should be.

Solution

4/1 * 2/3 = 4*2 / 1 * 3 = 8/3

The required value after simplification of the s = -16/3. None of these are correct.

Given that,
To simplify [\frac{x^{2/3}x^{-1/2}}{x\sqrt{x^3}\sqrt[3]{x}}]^2   and to find the value of s in x^s.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Simplification,

=[\frac{x^{2/3}x^{-1/2}}{x\sqrt{x^3}\sqrt[3]{x}}]^2\\= \frac{x^{4/3}x^{-1}}{x^2x^3*{x}^{2/3}}\\= \frac{x^{1/3}}{x^{17/3}}\\=x^{-16/3}
Comparing with x^S
s = -16/3


Thus, the required value of the s = -16/3. None of these are correct.

Complete the synthetic division problem below.
rewona [7]

Answer:

B

Step-by-step explanation:

- 2 | 2   2   - 2   4

      ↓  - 4    4   - 4

    --------------------------

      2   - 2   2    0 ← remainder

Since the remainder = 0 then (x + 2) is a factor

quotient = 2x² - 2x + 2
