Which set of values could be the side lengths of a 30-60-90 triangle? A. {4, 4 square root of 3, 8} B. {4, 4 square root of 2, 8 square root of 2} C. {4, 4 square root of 2, 8} D. {4, 4 square root of 3, 8 square root of 3}

Answers

Your answer is A.

When you have a 30-60-90 triangle, your sides will always have a set pattern. 

The side across from the 30 angle will be equal to n (in this case n = 4).

The side across from the 60 angle will always be equal to n√(3) (in this case, 4√(3)).

The side across from the 90 angle will always be 2n (in this case, 8).

You could go into trig or pythagorean theorem to prove this, but it's much simpler to remember it because it's a special triangle. 

So, you're answer is A.

Which of the following would NOT be an example of a long-term goal?a. lose 30 pounds in eight months
b. run a marathon in two years
c. run a 5k in three weeks
d. qualify for a triathlon in one year

Answers

Answering the question, run a 5k in three weeks would not be an example of a long-term goal. This implies the correct answer is c.

A Three weeks goal is too short to be considered a long term goal. A long term can be defined as a goal that set for individuals to achieve in a period of 3 to 5 years.

Further Explantion

Therefore, to run a 5k in three weeks will be considered a short-term goal and short-term goal is a goal that can be accomplished in a matter of few days.

In other words, you can achieve a short term goal very quickly but it will take you a longer period to achieve a long-term goal.

Some examples of long-term goal include

  • Lose 30 pounds in eight months
  • Run a marathon in two years
  • Run a 5k in three weeks
  • qualify for a triathlon in one year
  • To reduce your cholesterol level
  • To live a healthy to enjoy a long life
  • To get a bachelor’s degree
  • To learn to speak other languages
  • To purchase a home

Some of the examples of short-term goal include

  • Buying yourself a new phones
  • Washing your dishes
  • To learn new skills
  • To learn how to manage your time properly
  • To complete your project on time

KEYWORDS:

  • long-term goal
  • short-term goal
  • goal
  • three weeks
  • one year

The correct option is (c) run a 5k in three weeks.

Further explanation:

The long-term goal is a goal that an individual wants to accomplish in a long period of time. A long term is a goal that an organization or individual wants to accomplish or achieve in the future. If an individual set a goal to run 5k in three weeks then it would be considered as a short-term goal because three weeks is a short period of time.  

LONG-TERM GOAL AND SHORT-TERM GOALS

Goals are divided into two categories: long-term goal and short-term goal. A long-term goal is something that an individual wants to do in a long period of time or in the future while short-term goals are those goals which an individual wants to achieve in a short period that is in a week or month. A short-term goal can be achieved within 12 months. Every goal has some criteria, which are as follow:

  1. Have specific goal
  2. Goal must be measurable
  3. Don’t be negative
  4. Be realistic
  5. Reachable
  6. Be flexible

Solve for h in the mathematical formula V=pi r^(2)h

Answers

Answer:

(V)/(\pi r^(2) ) = h

Step-by-step explanation:

Lets try and get everything we can away from h.

V = \pir^(2) h

Divide \pir^(2) from both sides of the equation.

Now we end up with:

(V)/(\pi r^(2) ) = h

Rewrite 4/7 and 6/11 so that they have a common denominator.

Answers

For this, you have to calculate LCM of denominators i.e., 7 and 11 that will be 77

Now, 77/7 = 11, so 4*11=44 & 77/11 = 7, so 6*7=42

44/77 and 42/77 is the answer

Final answer:

To get a common denominator for the fractions 4/7 and 6/11, we find the least common multiple of 7 and 11, which is 77. The fraction 4/7 becomes 44/77 when both numerator and denominator are multiplied by 11, and the fraction 6/11 becomes 42/77 when both are multiplied by 7.

Explanation:

In simple terms, a common denominator is found by identifying the least common multiple (LCM) of the denominators you are working with.  In this instance, we are facing two fractions: 4/7 and 6/11. The LCM of 7 and 11 is 77, because 7 and 11 are both prime numbers and prime numbers only have one common multiple - their product.

So, you can rewrite these fractions as follows:

  1. For 4/7, you multiply both the numerator (the top number) and the denominator (the bottom number) by 11. This gives you 44/77.
  2. For 6/11, you multiply both the numerator and the denominator by 7. This gives you 42/77.

2. Another wooden plank is leaning against an outside wall of a building. The bottom of the plank is 9 ft from the wall. The length of the plank is 41 ft. Find each of the following values, and show all your work.(a) Find the value of x. Round to the nearest tenth of a degree.
(b) Find the height above the ground where the plank touches the wall. Round to the nearest foot.
Please someone help

Answers

(A) Find the value of x. Round to the nearest tenth of a degree
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft

In order to get the angle formed between the ground and the foot of the plank,

cos (theta) = ground / plank
cos (theta) = 9 / 41
cos (theta) = 0.21951...
theta = cos^-1(0.21951...)
theta = 77.3 degrees

(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.

Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
Height = square root (1600)
Height = 40

(A) 77.1 Degrees
(B) 40 feet
