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.

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

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:

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
