how to apply for teacher job?

Answers

Answer:

G oogle it, you will get different answers.

Step-by-step explanation:

To gain employment as a teacher, at least a bachelor’s degree is required. Some teachers choose to major in the subject area they plan to teach, such as English, history, or biology, but it is generally not a requirement to do so. In many states, including California, Massachusetts, and Pennsylvania, a master’s degree is also required in order to obtain a teaching certificate. For any state you teach in, a certificate or license specific to that state is required. The certificate is typically given after prospective teachers pass a state-specific teaching exam. Some states also require that teachers have some supervised experienced teaching, or that they have completed a teacher preparation program.

Skills for teachers

Teachers should be comfortable with speaking in front of people, and should have strong communication skills. Organization is also an important skill for teachers, as creating lesson plans, grading and handing back assignments, and keeping students on track for state exams all require attention to detail and the ability to stay organized. It is also important for teachers to have the ability to stay calm in chaotic situations and to mediate between young students. Answer:

a. What is the total cost of food and tip?

b. Felix and Jose want to leave a 20% tip based on the cost before tax. How much should they leave?
Help pls

Answers

Answer:

A, Total cost with tax; $29.68

B, Total cost of tip; $5.60

Step-by-step explanation:

28 x .2, accounting for the tip, is 5.6, aka $5.60. 28 x .06, accounting for the tax, is 1.68. Adding the original amount, the tax, and the tip, we are left with $35.28 in total after they have paid both the tax and the tip.

Which of these choices is a solution to the equation (x + 4)(x - 3) = -10?
a) 4
b) 3
C) -2
d) -1

Answers

The answer is C) -2

The solution of the given equation (x + 4)(x - 3) = -10 is -2.

Thus, option C is correct.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Example = 2x +4 = 12

Here, 4 and 12 are constants and x is variable

Given equation:

Multiply the brackets,

(x + 4)(x - 3) = -10

[tex]x^2-3x+4x-12 = -10[/tex]

x^2 +x -12+10 =0

x^2 +x -2=0

x(x+2)-1(x+2)=0

(x+2)(x-1)=0

x= -2, x=1

Thus, option C is correct.

Clyde bought a belt for $25 at a tax rate of 5%. He also bought a shirt $14 at a tax rate at 5%. What is the sum, in dollars, that he will pay including tax?

Answers

Answer:

40.95

Step-by-step explanation:

First, calculate the tax rate for the belt.

$25 is 1/4 of 100. 5% of 100 is 5, so the tax for 25 is 1/4 of 5, or 1.25.

Next, calculate the tax for the shirt. 14*0.05=0.7

Add everything together.

14+25+0.7+1.25=40.95

You see a hiker sitting on a bench taking a water break at the top of a hill at a 40° angle of elevation. Your eye level is 5 feet off the ground and you are standing 100 feet from the base of the hillAt what altitude is the hiker sitting on the bench?

Answers

Answer:

89

Step-by-step explanation:

Draw a right triangle, put the angle of elevation as 40 degrees and the feet for the base of your triangle (standing 100 feet from the base of the hill) as 100ft. According to SOH CAH TOA, we will be using tan, where you will get:

tan(40)=x/100

x=100tan(40)=83.9

Add 5 feet, which was your eyes off the ground, and it will be 83.9+5=89

Final Answer: 89

The altitude of the hiker sitting on the bench of the hill is 89 feet.

What is trigonometry?

Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.

For the given situation,

The angle of elevation = 40°

Distance from base of the hill = 100 feet

Distance from the ground to the eye level = 5 feet

The diagram below shows the right angled triangle.

Let the altitude from the eye sight to the bench be x.

Total altitude = x + 5

The altitude of the hiker can be found by using trigonometric ratio,

[tex]tan\theta= \frac{opposite}{adjacent}[/tex]

⇒ [tex]tan 40=\frac{x}{100}[/tex]

⇒ [tex]0.8390=\frac{x}{100}[/tex]

⇒ [tex]x=83.90[/tex]

Total height = [tex]x+5[/tex]

⇒ [tex]83.90+5[/tex]

⇒ [tex]88.90[/tex] ≈ [tex]89[/tex]

Hence we can conclude that the altitude of the hiker sitting on the bench of the hill is 89 feet.

Which of the following formulas shows how to calculate the ending balance of an account with a beginning balance of $600 that earns 3.5% compound interest over 8 years?

Answers

Answer:

[tex]A(t) = 600(1.035)^8[/tex]

The ending balance is of $790.1.

Step-by-step explanation:

Compound interest:

The amount of money earned after t years, in compound interest, is given by:

[tex]A(t) = A(0)(1+r)^{t}[/tex]

In which A(0) is the initial amount of money and r is the interest rate, as a decimal.

$600 that earns 3.5% compound interest over 8 years

This means, respectively, that:

[tex]A(0) = 600, r = 0.035, t = 8[/tex]

So, the formula is:

[tex]A(t) = A(0)(1+r)^{t}[/tex]

[tex]A(t) = 600(1+0.035)^{8}[/tex]

[tex]A(t) = 600(1.035)^8[/tex]

Ending balance:

The ending balance is:

[tex]A(t) = 600(1.035)^8 = 790.1[/tex]

The ending balance is of $790.1.

Find the area of the larger circle. ​

Answers

Answer:

65.94

Step-by-step explanation:

2 + 3 = 5

r = 5

Small circle:

r = 2

A = πr²

A=(3.14)2²

A = 12.56

Large circle:

r = 5

A = πr²

A=(3.14)5²

A = 78.5

78.5 - 12.56 = 65.94

Answers

Answer:

x = 49

Step-by-step explanation:

This is an inverse relationship and it implies that, an increase in the value of one variable results in a subsequent decrease in the value of another variable.

Given the mathematical expression and data;

y = 1/√x

y = 7 and x = 64

First of all, we would find the constant of proportionality, k;

y = k/√x

7 = k/√64

7 = k/8

k = 7 * 8

Constant, k = 56

Now, to find the value of x when y = 8

y = k/√x

Substituting the values, we have;

8 = 56/√x

Cross-multiplying, we have;

8 * √x = 56

√x = 56/8

√x = 7

Taking the square of both sides, we have;

(√x)² = 7²

x = 49

What is the measure of each interior angle of Regular Polygon?

Answers

Answer:

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.

Calculate the quadratic equation

[tex]x= -3 \ or\ 4[/tex]
