RQ= x+1 QP=7 RP=2x+8 solve for RP

### Answers

Answer:

RP = 8

Step-by-step explanation:

RQ + QP = RP (segment addition theorem)

(x + 1) + 7 = 2x + 8 (substitution)

Add like terms

x + 8 = 2x + 8

8 - 8 = 2x - x

0 = x

x = 0

✔️RP = (x + 1) + 7

Plug in the value of x

RP = (0 + 1) + 7

RP = 1 + 7

RP = 8

Solve using Cramer's rule. 3x + 2y = 5

### Answers

By applying **Cramer's rule** as **solution method**, the **solution** of the *linear* **system** 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the **set** (x, y) = (1, 1).

How to solve a system of two linear equations with two variables

**Determinants** are **constructions** studied in *linear* **algebra** and related to **matrices**, one of the most common applications of determinants is the **solution** of **linear equations**, whose simplest form is known as the **Cramer's rule**.

Now we proceed to use this rule to get the solution of the linear system:

[tex]x = \frac{\left|\begin{array}{cc}5&2\\4&3\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]x = \frac{(5)\cdot (3)-(4)\cdot (2)}{(3)\cdot (3) -(1)\cdot (2)}[/tex]

x = 1

[tex]y = \frac{\left|\begin{array}{cc}3&5\\1&4\end{array}\right| }{\left|\begin{array}{cc}3&2\\1&3\end{array}\right|}[/tex]

[tex]y = \frac{(3)\cdot (4) - (5)\cdot (1)}{(3)\cdot (3) - (1)\cdot (2)}[/tex]

y = 1

By applying **Cramer's rule** as **solution method**, the **solution** of the *linear* **system** 3 · x + 2 · y = 5 and x + 3 · y = 4 is equal to the **set** (x, y) = (1, 1).

A cube has a edge of 8 cm it is cur into two equal parts calculate the ratio of total surface area

### Answers

**Answer:**

[tex]Ratio = 3: 2[/tex]

**Step-by-step explanation:**

**Given**

**Shape: Cube**

[tex]L = 8cm[/tex]

**The surface area is calculated as:**

[tex]Area = 6*L^2[/tex]

[tex]A_1 = 6*8^2[/tex]

[tex]A_1 = 384[/tex]

**When it is cut by half; the length is affected; so, it forms a cuboid of the following dimension:**

[tex]L = \frac{8}{2} = 4[/tex] --- Length

[tex]W = 8cm[/tex] --- Width

[tex]H = 8cm[/tex] --- Height

**The surface area is:**

[tex]Area = 2 *(L*W + H * L + W * H)[/tex]

[tex]A_2 = 2 *(4*8 + 8 *4 + 8 * 8)[/tex]

[tex]A_2 = 2 *128[/tex]

[tex]A_2 = 256[/tex]

**So, the ratio of surface area is:**

[tex]Ratio = A_1 : A_2[/tex]

[tex]Ratio = 384 : 256[/tex]

**Divide by 128**

[tex]Ratio = 384/128 : 256/128[/tex]

[tex]Ratio = 3: 2[/tex]

D. (8, -5)

### Answers

**Answer:**

A

**Step-by-step explanation:**

3*4 +2*(-3)=6

12-6=6

6=6 which is true

**Answer:**

A. (4, -3)

**Step-by-step explanation:**

substitute x and y for 4 and -3 so the equation would be 3(4) + 2(-3) = 6 and 4 times 3 = 12 and 2 times -3 = -6 so then the equation would be 12 + (-6) = 6 or 12 - 6 = 6. Therefore, the answer A is correct

If the Diameter is 10 inches, what is the Radius? 2.5 inches 5 inches 10 inches 20 inches

### Answers

the radius is half of the diameter

so 5 inches

**Answer: Radius is always half of the diameter so the answer is 5**

**Step-by-step explanation:**

A,B,C, and D are all answer choices

A common way for two people to settle a frivolous dispute is to

play a game of rock-paper-scissors. In this game, each person

simultaneously displays a hand signal to indicate a rock, a piece

of paper, or a pair of scissors. Rock beats scissors, scissors

beats paper, and paper beats rock. If both players select the

same hand signal, the game results in a tie.

Two roommates, roommate A and roommate B, are expecting

company and are arguing over who should have to wash the

dishes before the company arrives. Roommate A suggests a

game of rock-paper-scissors to settle the dispute.

Consider the game of rock-paper-scissors to be an experiment. In the long run, roommate A chooses rock 36% of the time, and

roommate B chooses rock 22% of the time; roommate A selects paper 32% of the time, and roommate B selects paper 25% of

the time; roommate A chooses scissors 32% of the time, and roommate B chooses scissors 53% of the time. (These choices are

made randomly and independently of each other.)

The probabilities were assigned using the

-------------------------

Define event A as the event that roommate A wins the game and thus does not have to wash the dishes.

What is P(A), the probability of event A?

a P(A) = 0.32

b P(A) = 0.22

c P(A) = 0.34

d P(A) = 0.38

Let event C be the event that the game ends in a tie.

What is P(C), the probability of event C?

a P(C) = 0.44

b P(C) = 0.33

c P(C) = 0.55

d P(C) = 0.25

Define event B as the event that roommate B wins the game and thus does not have to wash the dishes. What is the probability

that roommate B wins the game?

a P(B) = 0.67

b P(B) = 0.43

c P(B) = 0.33

d P(B) = 0.50

### Answers

Answer:

0.33

A^c = event B or event C

Step-by-step explanation:

A = roommate A wins the game

P(A) = (Rock A and Scissors B) + (Scissors A and paper B) + (paper A and rock B)

P(A) = (0.36*0.53) + (0.32*0.25) + (0.32*0.22) = 0.3412

C = game ends in a tie :

P(C) = (RockA and rockB) + (ScissorsA and ScissorsB) + (ScissorsA and ScissorsB)

P(C) = (0.36*0.22) + (0.32*0.53) + (0.32*0.25) = 0.3288

P(B) = 1 - P(A) - P(C)

P(B) = 1 - 0.3412 - 0.3288

P(B) = 0.33

If 4x - 3y = -18 and 6x + 7y = -4, then what is the value of y?

### Answers

**Answer:**

y = 2

**Step-by-step explanation:**

4x - 3y = -18, then 4x = 3y - 18, x = (3y - 18)/4

6x + 7y = -4

substitute for x:

6((3y - 18)/4) + 7y = -4

(18y - 108)/4 + 7y = -4

4.5y - 27 + 7y = -4

combine like terms:

11.5y = 23

y = 2

check:

x = (3(2) - 18)/4 = -12/4 = -3

6(-3) + 7(2) = -4

-18 - 14 - -4

-4 = -4

so y = 2 is correct

PLEASE HELP

For the right triangles below, find the values of the side lengths b and c.

Round your answers to the nearest tenth.

**Answer:**

b = 1.7

c = 7.1

**Step-by-step explanation:**

the triangle with side 'b' is a 30-60-90° Δ where the ratio of sides, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2

to find 'b' we could set up this proportion:

b/3 = 1/[tex]\sqrt{3}[/tex]

cross-multiply:

b[tex]\sqrt{3}[/tex] = 3

b = 3 / [tex]\sqrt{3}[/tex]

if we rationalize the denominator, this becomes (3[tex]\sqrt{3}[/tex])/3 which is [tex]\sqrt{3}[/tex] or 1.7

the other triangle is a 45-45-90°Δ where the ratio of the sides are 1 : 1 : [tex]\sqrt{2}[/tex]

if the legs are 5 then the hypotenuse is 5[tex]\sqrt{2}[/tex] or 7.1
