Answer:

a. (5x - 2)° + (2x - 2)° + x° = 180°

b. m<113°,

m<K = 44°,

m<L = 23°

Step-by-step explanation:

Given:

m<J = (5x - 2)°

m<K = (2x - 2)°

m<L = x°

Required:

a. the equation to find x,

b. m<J, m<K, and m<L

Solution:

a. m<J + m<K + m<L = 180° (sum of triangle)

Substitute

(5x - 2)° + (2x - 2)° + x° = 180°

Solve for x

5x - 2 + 2x - 2 + x = 180

Add like terms

8x - 4 = 180

8x - 4 + 4 = 180 + 4

8x = 184

8x/8 = 184/8

x = 23°

b. ✔️m<J = (5x - 2)°

Plug in the value of x

m<J = 5(23) - 2 = 113°

✔️m<K = (2x - 2)° = 2(23) - 2

m<K = 44°

✔️m<L = x = 23°

p = pencil

1.97n + 1.16p = 21.45

A)✅

1.97(5) + 1.16(10) = 21.45

9.85 + 11.6 = 21.45

21.45 = 21.45

B) ❌

Which of the following is a solution to the equation y=-1/4x +8 O (10,8) 0 (48) O (49) O (-8.-10)

### Answers

**Answer:**

**Step-by-step explanation:**

The last one -- D -- is the closest correct answer. None of them, however, is right.

y = -1/4 x + 8 Let x = - 8

y = -1/4 * - 8 + 8 The standard rule is starting from the left, do the multiplication first then do the addition

- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.

-1/4 * - 8 = 1/4 * 8

1/4 * 8 = 2

y = 2 + 8

y = 10

So the ordered pair (-8 , 10) is the answer.

Find the scale factor of the dilation. Then tell whether the dilation is a reduction or an enlargement

### Answers

**Answer:**

The answer is "[tex]\frac{3}{7}[/tex]"

**Step-by-step explanation:**

Please find the complete question:

The dilation scale factor will be the same:

[tex]=\frac{\text{Picture to Center Gap}}{\text{Related pre-image distance to the middle}}[/tex]

Throughout the picture, the distance is [tex]CP'=6[/tex], while the equivalent distance is [tex]CP=14[/tex]. The factor of scale is then[tex]=\frac{CP'}{CP} =\frac{6}{14} =\frac{3}{7}[/tex]

The decrease because if a factor of scale is below 1 and a factor of scale is higher than 1. Dilation is a reduction since [tex]\frac{3}{7}<1[/tex], therefore the scale factor is [tex]\frac{3}{7}[/tex].

The **scale factor** of the given dilation is; 6/14 and the dilation is a reduction

**Transformations**

The image of the object undergoing **transformation** is missing and so i have attached it.

From the attached object, we se that CP = 14.

Also CP' = 6

Thus; **Scale factor** is 6/14

Now, reduction is reducing the dimensions while **enlargement** is increasing the dimensions by a **scale factor.**

Since the denominator of the** scale factor** is greater than the numerator, then there is a **reduction.**

Flip a fair coin 5 times. Let random variable X = "number of heads."What is P(X = 1)?

### Answers

Answer:

The probability is 1/32

Step-by-step explanation:

What the question asks here is that in a throw of a coin 5 times, what is the probability that we have the head being revealed once in the 5 throws

for a fair coin, we can only get a head or a tail

So the probability of getting a head equals that of getting a tail

Since total probability is 1; then the probability of each will be 1/2

So, we can now have the probability as follows;

1 head (1/2) and 4 tails (1/2 * 1/2 * 1/2 * 1/2)

1/2 * 1/2 * 1/2 * 1/2 * 1/2 = (1/2)^5 = 1/32

While looking at some reports, a store manager notes that chandeliers that retail for $57 end up costing customers $58.14 once the sales tax is added. What is the sales tax percentage?

### Answers

**Answer:**

The sales tax percentage is 2%.

**Step-by-step explanation:**

With the information provided, you can find the sales tax percentage by subtracting the retail price from the amount the customer paid and dividing that by the retail price. Then, you have to multiply the result by 100.

((58.14-57)/57)*100= (1.14/57)*100=0.02*100= 2%

According to this, the answer is that the sales tax percentage is 2%.

### Answers

**Answer:**

√53

**Step-by-step explanation:**

**Formula**

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

**Givens**

x1 = -5

x2 = -3

y1 = 6

y2 = - 1

**Solution**

d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )

d = sqrt( ( -3 + 5)^2 + (-7)^2 )

d = sqrt( 2^2 + 49)

d = sqrt(4 + 49)

d = sqrt(53)

I don’t understand question 42,43

### Answers

**Answer:**

42. x = 25

43. LM = 11

**Step-by-step explanation:**

For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.

So: 90 + 2x + x + 15 = 180

105 + 3x = 180

3x = 75

x = 25

If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180

For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.
