Need help FAST, 25 points. Calculate the value of x

Answer:

Cost of the manicure= $27

Step-by-step explanation:

Giving the following information:

Darcy gave her nail technician a ​$5.40 tip. The tip was 20% of the cost of the manicure

To calculate the cost of the manicure, we need to use the following formula:

Cost of the manicure= tip / tip percentage

Cost of the manicure= $27

Answer:

D

Step-by-step explanation: the answer is d because the other half without the equations is = to 180 which is a semi circle. This means that the other half must be 180 too because a circle is 360. I did trial and error and plugged in all the numbers.

Hope I could help!

Answer:

option D .35

Step-by-step explanation:

2x+3x+5=180 linear pair

5x=180-5

x=175/5=35

Answer:

B = 155°, C = 25°, D = 155°

Step-by-step explanation:

Assuming you require B, C, D

A and B are adjacent angles and are supplementary , that is

A + B = 180°

25° + B = 180° ( subtract 25° from both sides )

B = 155°

A and C are vertically opposite angles and are congruent, then

C = 25°

B and D are vertically opposite angles and are congruent , then

D = 155°

Step-by-step explanation:

step 1. since we have a right triangle we can use trigonometry

step 2. <A: 5 is the opposite and 8 is the hypotenuse so we use sine

step 3. sinA = opp/hyp = 5/8

step 4. A = 38.68° using inverse sine on your calculator.

Answer:x-intercepts (0,2) ; (0,3)

Step-by-step explanation:

x^2 - 5x + 6 =0

(x-2)(x-3) = 0            

[-2 and -3 was the factors of 6, which make them equal to -5 when them add].

x-2=0            x-3=0

   x=2               x=3

so x-intercepts (0,2) ; (0,3)

Answer:

The answer is 0.3 repeating or in a fraction 1/3

Step-by-step explanation:

All you have to do is divide 1/5 th by 6 and then make it a fraction it's not that hard.

Answer:

B: -2

Step-by-step explanation:

When you minus a negative number, it is like adding the absolute value of the negative value, so:

-6-(-4)

=-6+4

=-2

The answer is B: -2

Answer:

62.2° (or 1.1 rad)

Step-by-step explanation:

Let’s call the three points A Allen’s house, B Bob’s house, T the traffic light and α “angle of depression”.

Since we have a right triangle BTA, let’s first find out the angle ∡BTA based on its opposite side AB = 7 km and the hyponenuse TA = 15 km.

∡BTA = arcsin(AB/TA) ≈ arcsin(0.4667) ≈ 0.4855 rad or 27.82°

Now since the text says the connecting line TA “is vertical to the road”, α is the rest of the right angle when ∡BTA subtracted.

α ≈ 90° - 27.82° = 62.18°

or α ≈ 0.5 π rad - 0.4855 rad ≈ 1.09 rad

See above for properly rounded values.

Answer:

2x 2 x 2 x 2= 8 + 1 = 9?

Step-by-step explanation:

The solution of the equation 2x + 1 = 9 will be 4.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The equation is given below.

2x + 1 = 9

Simplify the equation, then we have

2x + 1 = 1

2x = 9 - 1

2x = 8

x = 8 / 2

x = 4

The solution of the equation 2x + 1 = 9 will be 4.

Answer:

4) D) 20

3) A) 16°

Step-by-step explanation:

4)

You must follow the correct order of operations.

13 - 2(1 - 15)/4 =

Do the subtraction inside the parentheses first.

= 13 - 2(-14)/4

Now multiply -2 by -14.

= 13 + 28/4

Divide 28 by 4.

= 13 + 7

Finally, add.

= 20

Answer: D) 20

The sum of the measures of the angles of a triangle is 180°.

Let the unknown angle have measure x.

x + 41° + 123° = 180°

x + 164° = 180°

x = 16°

Answer:

A) 16°

Step-by-step explanation:

- 9x + 5y - 8

Answer:

x = 34

Step-by-step explanation:

according to the problem ::

(2x + 9)° + (3x + 1)° = 180° [ since, the opposite angles of a cyclic quadrilateral are supplementary ]

or, 2x + 9 + 3x + 1 = 180

or, 2x + 3x = 180 - 10

or, 5x = 170

or, x = 170 / 5

or, x = 34

therefore, the value of x is 34°

Answer:

I agree with Jamie

Step-by-step explanation:

Given the inequality expression -2°C > -5°C, to compare both temperatures, we are to determine whether we agree or disagree with him.

Note that negative values that are closer to zero on the number line are greater than those that are far from zero. Hence, since -2 is closer to zero on the number line than -5, this means that -2 is greater than -5 hence I agree with Jamie's temperature value comparison.

Answer:

Step-by-step explanation:

By triangle sum theorem,

73°+ 39° + m∠1 = 180°

m∠1 = 180° - 102°

m∠1 = 78°

Since, m∠1 = m∠2 [Vertically opposite angles]

m∠2 = 78°

Sum of interior angles of a polygon = (n - 2)×180°

Where n = number of sides of the polygon

Sum of the interior angles of a quadrilateral = (4 - 2)×180°

= 360°

Therefore, 77° + m∠3 + 90° + m∠2 = 360°

77° + m∠3 + 90° + 78° = 360°

m∠3 = 360° - 245°

m∠3 = 115°
