Rhada has a 6-pound bag of day . Her craft project requires 6 ounces of clay for each batch of 3 ornaments,
kirill [66]

Answer:

Rhada can make 48 ornaments if she uses all of the clay.

Step-by-step explanation:

The complete question is:

Rhada has a 6-pound bag of day . Her craft project requires 6 ounces of clay for each batch of 3 ornaments. If she uses all of the clay, how many ornaments can Rhada make?

Solution:

The amount of clay Rhada has, <em>X</em> = 6-pound.

Convert the weight of clay bag into ounces as follows:

1 pound = 16 ounces

6 pound = 16 × 6

              = 96 ounces.

So, Rhada has 96 ounces of clay.

It is provided that her craft project requires 6 ounces of clay for each batch of ornaments.

Compute the number of batches that can be made by 96 ounces of clay as follows:

Number of batches = Total weight of clay ÷ Amount required for each batch

                                =\frac{96}{6}\\=16

Thus, Rhada can make 16 batches of ornaments.

Now, it is also provided that each batch has 3 ornaments.

Compute the number of ornaments in 16 batches as follows:

Number of ornaments = Number of batches × No. of ornament in 1 batch

                                     =16\times 3\\=48

Thus, Rhada can make 48 ornaments if she uses all of the clay.

Find the value of x A. 2 B. 4 C. 6 D. 8
nasty-shy [4]

Hello from MrBillDoesMath!

Answer:

Choice B, 4


Discussion:

From the Pythagorean Theorem


x^2 + ( x-2)^2           =    ( sqrt(20) ) ^ 2     =>

x^2 + ( x^2 - 4x + 4) = 20                            => combine common terms

2x^2 -4x + 4 = 20                                        => divide both sides by 2

x^2 -2x + 2 = 10                                           => subtract 10 from both sides

x^2 -2x - 8 = 0                  => x^2 -2x - 8 = (x-4)(x+2)

(x-4)(x+2) = 0                    =>

x = 4, x = -2

The answer is Choice B, 4


Thank you,

MrB
