### Answers

Stefano's movement on the canyon is an illustration of elevation.

The difference in elevation is (b) 176 meters

Using the table as a guide.

- At 6 seconds, the height of the sunglass is -166.4 meters
- At the starting point (when t = 0), the height of the sunglass is 10 meters

So, the difference between the heights is:

Evaluate

Remove absolute brackets

Approximate

Hence, the difference in elevation is (b) 176 meters

The coordinates of the mid - point of the line AB is (-1, -5).

What is mid - point?

A midpoint is a point that divides a given line into two equal parts.

Given is that AB has endpoints at A(4, -8) and B(-6, -2). It is asked to find the coordinates of the midpoint of AB.

We can write the coordinates of the midpoint of AB as -

{x} = (x₁ + x₂)/2

{x} = (4 - 6)/2

{x} = - 2/2

{x} = -1

{y} = (y₁ + y₂)/2

{y} = (-8 - 2)/2

{y} = - 10/2

{y} = - 5

Therefore, the coordinates of the mid - point of the line AB is (-1, -5).

### Answers

You would have to add 3 to both sides and then divide both sides by 12. your answer would be 1/2.

Answer: x = 2

Make -3 into a positive 3 and move it to the right.

### Answers

No; the sample is not selected from the population to be studied.

Answer: Option A.

Explanation:

In statistics and quantitative research philosophy, a sample is a lot of people or articles gathered or chose from a factual populace by a characterized method. The components of an example are known as test focuses, inspecting units or perceptions.

In the sample that has been taken above in this question is not the appropriate sample to solve the purpose of the average. Because the purpose is to solve for the population of the whole country but sample is not taken from the whole country.

A store has a total supply of 250 pairs of shoes the shoes are selling at a rate of 10 Paris every hour the store has already sold 177 Paris of shoes

### Answers

Answer:

17 hours and 42 minutes.

Step-by-step explanation:

the store has a total supply of 250 pairs of shoes which sells 10 pairs of shoes every hour and it has already sold 177 pairs of shoes. So to find out the time needed to sell 177 pairs at a constant rate of 10 pairs every hour.

177 pairs = 17,7 hours or 17 hours and 42 minutes (70% off 60 = 42).

Ramu observed that in order toclimb a 12 meter high wall, he requires either a 13meter or a 20 meter long ladder if he keeps them at distances of x and y respectively from the foot of the wall assume that the ladders just touch the top of the wall what is the value of x + y? pls tell fast will mark brainliest

### Answers

21 meters

Step-by-step explanation:

Step 1 :

Let x be the distance at which the 13 meter ladder is placed . We can consider this as a triangle with one angle as 90°, where the ladder is the hypotenuse and the wall is one side. We need to find the 3rd side x.

Using Pythagoras theorem, we have

13² = 12² + x² => 169 = 144 + x² => x² = 169-144 = 25

=> x = 5 meters

Step 2 :

Similarly ,

Let y be the distance at which the 20 meter ladder is placed . We can consider this as a triangle with one angle as 90°, where the ladder is the hypotenuse and the wall is one side. We need to find the 3 rd side which is y.

Using Pythagoras theorem, we have

i.e 20² = 12² + y² => 400 = 144 + y² => y² = 200-144 = 256

=> y = 16 meters

Step 3 :

Value of x + y = 5 + 16 = 21 meters

### How do you prove that √ 2 is an irrational number? ›

**√2 = p/q, where 'p' and 'q' are integers, q ≠ 0 and p, q have no common factors (except 1)**. Thus, p and q have a common factor 2. This statement contradicts that 'p' and 'q' have no common factors (except 1). We can say that √2 is not a rational number.
