Rosa and Kyle solve problems using blocks of five different colors: white, red,yellow,blue,and purple. All blocks of the same co

Fudgin [204]

Answer:

Please read the answers below

Step-by-step explanation:

1. Let's review the information provided to us to answer the questions correctly:

1 white block weights 2 ounces

6 white blocks = 3 red blocks

1 blue block = 3 white blocks + 4 red blocks

1 yellow block = 4 blue blocks + ? white blocks + ? red blocks

2 purple blocks = 1 white block + 1 red block + 1 blue block + 1 yellow block

2. How much does 1 red block weight? Explain.

Let's answer this question, this way:

6 white blocks = 3 red blocks

6 * 2 ounces = 3 red blocks

3 red blocks = 12 ounces

1 red block = 12/3 ounces = 4 ounces

3. What is the weight of one blue block?

1 blue block = 3 white blocks + 4 red blocks

1 blue block = 3 * 2 + 4 * 4

1 blue block = 6 + 16

1 blue block = 22 ounces

4. To balance one yellow block, it takes 4 blue blocks, and some white and red blocks. The number of white blocks is 3.5 times the number of blue blocks. The number of red blocks is 1.25 times the number of blue blocks.

White blocks = 3.5 * 4 = 14

Red blocks = 1.25 * 4 = 5

Yellow block = 4 blue blocks + 14 white blocks + 5 red blocks

Yellow block = 4 * 22 + 14 * 2 + 5 * 4

Yellow block = 88 + 28 + 20 = 136 ounces

5. What is the weight of one purple block?

2 purple blocks = 1 white block + 1 red block + 1 blue block + 1 yellow block

2 purple blocks = 2 + 4 + 22 + 136

2 purple blocks = 164 ounces

1 purple block = 164/2 = 82 ounces

6. Rosa challenges Kyle to balance a purple block by using only one other color of block. Which color block should Kyle choose? Explain.

Actually there are two options:

A. 1 purple block = 41 white blocks

82 ounces = 41 * 2 ounces

82 ounces = 82 ounces

B. 2 purple blocks = 41 red blocks

2 * 82 = 41 * 4

164 ounces = 164 ounces

Write an equation in standard form using integers Y= 43 - 4x

Blizzard [7]

Answer:

4x + y = 43

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = 43 - 4x ( add 4x to both sides )

4x + y = 43 ← in standard form

In circle A, ∠BAE ≅ ∠DAE. Circle A is shown. Line segments A B, A E, and A D are radii. Lines are drawn from point B to point E

xeze [42]

Answer:

The missing figure is attached down

The length of BE is 27 units ⇒ 3rd answer

Step-by-step explanation:

In circle A:

∠BAE ≅ ∠DAE
Line segments A B, A E, and A D are radii
Lines are drawn from point B to point E and from point E to point D to form secants B E and E D
The length of B E is 3 x minus 24 and the length of E D is x + 10

We need to find the length of BE

∵ AB and AD are radii in circle A

∴ AB ≅ AD

In Δs EAB and EAD

∵ ∠BAE ≅ ∠DAE ⇒ given

∵ AB = AD ⇒ proved

∵ EA = EA ⇒ common side in the two triangles

- Two triangles have two corresponding sides equal and the

including angles between them are equal, then the two

triangles are congruent by SAS postulate of congruence

∴ Δ EAB ≅ Δ EAD ⇒ SAS postulate of congruence

By using the result of congruence

∴ EB ≅ ED

∵ EB = 3 x - 24

∵ ED = x + 10

- Equate the two expressions to find x

∴ 3 x - 24 = x + 10

- Add 24 to both sides

∴ 3 x = x + 34

- Subtract x from both sides

∴ 2 x = 34

- Divide both sides by 2

∴ x = 17

Substitute the value of x in the expression of the length of BE to find its length

∵ BE = 3 x - 24

∵ x = 17

∴ BE = 3(17) - 24

∴ BE = 51 - 24

∴ BE = 27

The length of BE is 27 units
