Is x = 3 a solution to the equation x + 7 = 11?

Answers

Answer:

Step-by-step explanation:

3+7 is 10, not 11. Therefore, x cannot be 3.

Answer:

The correct answer is A. No, because 3 + 7 = 11 is not true.

Step-by-step explanation:

Just like the answer says, if x =3, then that would mean that 3 + 7 = 11. Since

3 + 7 =10, this statement is not true.

Therefore, the correct answer is A.

Step-by-step explanation:

A zip-line at a water park runs from the top of a wall, down to the ground on the other side of a pool. The top of the zip cord is 45 ft above the ground and the zip-line is 500 ft long. What is the horizontal distance between the wall and the end of the zip-line? Round your answer to the nearest foot.

Answers

Answer:

498 ft

Step-by-step explanation:

The zip-line, wall and end of the zip-line to wall form a right-angled triangle.

Since the zip-line which is 500 ft long represents the hypotenuse side, the top of the zip cord to the ground represents one side of the triangle which is 45 ft long and the third side is represented by the horizontal distance between the wall and the zip-line.

By Pythagoras' theorem,

L² = h² + d² where L = length of zip-line = 500 ft, h = height of top of zip cord from ground = 45 ft and d = horizontal distance between the wall and the zip-line.

So, d² = L² - h²

d² = (500 ft)² - (45 ft)²

d² = 250,000 ft² - 2025 ft²

d² = 247,975 ft²

d = √247,975 ft²

d = 497.97 ft

d ≅ 498 ft

The horizontal distance between the wall and the end of the zip-line is:498 ft.

Horizontal distance

Using Pythagoras theorem formula

d= √L² + h²

Let plug in the formula

d=√500 ft² - 45 ft²

d=√ 250,000 ft² - 2025 ft²

d = √247,975 ft²

d = 497.97 ft

d= 498 ft (Approximately)

Inconclusion the horizontal distance between the wall and the end of the zip-line is:498 ft.

question Today, everything at Nike is on sale. The store offers a 25% discount.
The regular price of a pair of shoes is $125. What is the discount price?

Answers

Answer:

$93.75

Step-by-step explanation:

First step, we need to find 25% of 125, we can do this by multiplying .25 by 125. This leaves us with $31.25. Now, we subtract 31.25 from 125, this leaves us with $93.75. There is your answer. Another way to do this is to find 75% of 125 because 25+75 equals 100.

In two or more complete sentences, explain the theorem used in solving for the range of possible lengths of the third side, AB of ABC.

Answers

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:

a² = b²+c²

As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:

b = √(a²-c²) b = √(10²-4²) b = 9.16

With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10

We already know that one angles is 90 degrees and that the full degrees inside a triangle is 180

So minus 90 from 180 and you get 90.

Since the other two angles are congruent that means they have the same measure so divide 90 by 2 to get the measure of both angles which is your answer
