Answer : The XZ is congruent to AC.

Step-by-step explanation :

First we have to prove ΔOBC and ΔOYX are congruent triangles.

Proof:

Side OC = Side OX (radius of same circle)

Side OB = Side OY (equal to 22)

∠B = ∠Y (equal to 90°)

ΔOBC ≅ ΔOYX (By SAS congruency)

So, Side BC = Side YX (By CPCT)

Similarly, Side AB = Side ZX

Or we can say that,

Chord XZ = Chord AC

Hence, the XZ is congruent to AC.

Robert earned $10, which was 4 less than twice what Eric earned , How much money did Eric earn?

Kisachek [45]

Answer:

Eric's earning is $7

Step-by-step explanation:

Given

Represent Robert's earnings with R and Eric's with E.

$R = 10\\R = 2E - 4$

Required

What is the value of E?

Substitute 10 for R in the second equation.

$10 = 2E - 4$

Solve for 2E

$2E = 10 + 4$

$2E = 14$

Solve for E

$E = 14/2$

$E = 7$

Eric's earning is $7

Nancy Wallin has just purchased a new house that is in need of new flooring. The cost of Pergo Select Helsinki Birch laminate fl

Yuri [45]

Answer:

Part A: Cost for the flooring is $ 4,231.50

Part B: Cost for the flooring is $ 5,531.50

Step-by-step explanation:

Step 1:

Let's calculate the area of the living/dining room, this way:

Area = 26 * 25

Area = 650 ft²

Step 2:

Let's calculate the cost of the flooring if Nancy installs it:

Cost = $ 6.51 * Area of the living/dining room

Cost = 6.51 * 650

Cost = $ 4,231.50

Step 3:

Let's calculate the cost of the flooring if the flooring company installs it:

Cost = $ 8.51 * Area of the living/dining room

Cost = 8.51 * 650

Cost = $ 5,531.50

Explain why both Jenna and Mia arrived at the same answer and the advantage of one method over the other.

Lynna [10]

Complete question :

Jenna’s method: Mia’s method: 5(30 + 4) 5(30 + 4) (5)(30) + (5)(4) 5(34) = 170 150 + 20 = 170 Explain why both Jenna and Mia arrived at the same answer and the advantage of one method over the other.

Answer:

Kindly check explanation

Step-by-step explanation:

Jenna's method :

5(30 + 4) = 5(34) = 170

Mia’s method :

5(30 + 4) :

5(30) + 5(4)

150 + 20

= 170

With both methods, we will arrive at the same answer as justified in the workings above. However, Jenna's method gives a very simple approach and less complicated arithmetic by using the distributive property to overrode some multiplication process which Mia went through in her own calculation. Therefore, Jenna's method is less complicated and requires two simple steps at obtaining the final result.
