Dustin says that FGH is an equilateral triangle because the sides appear to be the same length.Is his reasoning valid?Explain

Answers

His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.

So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.   

A straight angle is an angle whose measure is equal to _____.a. 45°
b. 60°
c. 90°
d. 180°

Answers

A straight angle is a straight line which is 180°
answer is d. 180°

April has four different basil plants and four different tomato plants. In how many ways can she arrange the plants in a row if she puts all the tomato plants next to each other?

Answers

The total no. of different arrangements of plants is 5!=120.

Concept of Permutation

Suppose if we had 4 plants, then the total no. of different ways through which it can be arranged in a row is 4!=4.3.2.1

{This simply means first position has 4 options, second has 3 options and so on}

Now In this question, considering the given condition there are :

4 different basil plants and 1 group(4 tomato plants) {As they need to stay together}

So there are 5 different entities

Therefore the total no. of arrangements are 5!=5.4.3.2.1

Therefore in 120 different ways she can arrange given plants in a row.

well you have to multiply 4 times 4 because you have 4 tomatoe plants and 4 basil plants so you just multiply 4×4

A surveyor is shooting a line to a point on a tree 55 m from his current position. After rotating his surveying instrument 25" to the left, he shoots another line to a point on a fence post 25 m away.Determine the distance between the point on the tree to the point on the fence post. ( show the appropriate formula , substitutions, and work. Give the distance to the nearest hundredth of a meter)

Answers

Take a look at the diagram below.
This problem looks like a great candidate for using the Law of Cosines.
If you know two sides, you can find the third side from the angle opposite or vice versa. Should the sides be a, b, and c, and their opp. angles A, B, and C...
a² + b² - 2ab(cosC) = c²

Let's plug in what we know...a = 55, b = 25, and m<C = 25".

55² + 25² - 2(55)(25)(cos(25")) = c²

One thing to note is that our angle measure is in seconds. Unless you're using Google's built in calculator, you'll wind up having to convert to degrees. 60 seconds in a minute, 60 minutes in a degree...blahblahblah.
Anyways, cos(25") comes out to be practically 1. (0.99999993)
Let's get evaluating.

3025 + 625 - 2750(1) = c²
3025 + 625 - 2750 = c²
900 = c²
30 = c

The tree is 30 meters from the fence post.

Plz help :-)The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.​

Answers

Question:

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.

Solution:

  • The perimeter of an equilateral triangle is 9n - 12.
  • We know, perimeter of a triangle is the sum of the three sides of the triangle.
  • Also, in an equilateral triangle, all the sides are equal.
  • Therefore, the length of each side of the triangle

=  (9n-12)/(3)  \n  =  (3(3n - 4))/(3)  \n  = 3n - 4

Answer:

The length of each side of the triangle is 3n-4.

Hope it helps!!

Answer:

9n - 12  \rightarrow  (1)/(3) (9n - 12) \n  =  (3)/(3) (3n - 4) \n l = 3n - 4

In a certain county, the number of charter schools is 6 less than twice the number of alternative schools. We know that there are 52 charter schools in the county. How many alternative schools are in the county?

Answers

Answer:

29

Step-by-step explanation:

Answer:

29

Step-by-step explanation:

So, 52 charter schools and the number is 6 less than the alternative schools doubled. In order to find the number of alternative schools, we need to reverse the equation. 52+6=58. That means 58 is twice the amount of alternative schools. 58/2 equals 29, therefore the answer is 29
