A ramp of 13 feet in length is constructed in front of a house that is at a height of 5 feet from the ground. What is the horizontal distance between the front door and the point where the ramp touches the ground?

Answers

Answer 1
If you picture it, it will be a right angled triangle. This means you can use the Pythagorean theorem.

The hypotenuse is 13ft and one side is 5ft

So....

13ft^2 - 5ft^2 = 144

Square root 144 to get 12

Therefore the distance is 12ft

Hope this helps! Any questions let me know :)
Answer 2

The horizontal distance between the front door and the point where the ramp touches the ground will be equal to 12 feet.

What is the Pythagoras' Theorem?

According to the Pythagoras theorem, if a triangle has a straight angle (90 degrees), the hypotenuse's square is equal to the total of its other two sides' squares.

As per the given information in the question,

Length of the ramp, h = 13 feet

Height of ramp from the ground, p = 5 feet

Let the horizontal distance is b.

Then, use the equation of Pythagoras' Theorem,

h² = p² + b²

13² = 5² + b²

b² = 169 - 25

b = √144

b = 12 feet.

In the oak forest, 60 kids are playing capture the flag.That is 40 percent of all kids in the park.How many kids are in the park?

Answers

Answer:

150 kids

Step-by-step explanation:

If 60 kids is 40% of the total kids, we can add another 60 to get 80% and then half of 60 (30) to bring the total up to 100% of the kids.

150 kids because if you did the percents right then you would get the total and then divide it

Step-by-step explanation:

The solution of equations are one solution, infinitely many solutions, one solution and no solution.

We are given that;

The four equations

Now,

To determine whether an equation has no solution, one solution, or infinitely many solutions, we can try to solve for the variable and see what happens.

Let's apply this method to each equation:

a. 8p + 1 = 4p + 2

4p + 1 = 2

Subtracting 1 from both sides, we get:

4p = 1

p = 1/4

This is a consistent result, so the equation has one solution: p = 1/4.

b. -6p + 7 = 7 - 6p

Adding 6p to both sides, we get:

7 = 7

This is an identity, so the equation has infinitely many solutions. Any value of p will satisfy the equation.

c. p + 9 = 2p - 3

Subtracting p from both sides, we get:

9 = p - 3

Adding 3 to both sides, we get:

12 = p

This is a consistent result, so the equation has one solution: p = 12.

d. 5p + 3 = 5p - 1

Subtracting 5p from both sides, we get:

3 = -1

This is a contradiction, so the equation has no solution.

Therefore, by the equation answer will be one solution, infinitely many solutions, one solution and no solution.

Answers

Answer:

The answer is 68 and 52

Step-by-step explanation:

x + y = 120

3(x - y ) = 48

We have 3x + 3y = 360

and 3x - 3y = 48

Adding we have the following:

6x = 408

x = 68

y = 120-48 = 52

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?

Answers

9514 1404 393

Answer:

  K(-14 1/3, -34 2/3)

Step-by-step explanation:

The division ratio says ...

  (L -J)/(K -L) = 3/2

  2(L -J) = 3(K -L)

  5L -2J = 3K

  K = (5L -2J)/3

  K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)

  K = (-14 1/3, -34 2/3)

7x + 5 = 7x + 5 (Combine Like Terms)

0 = 0 (Subtraction Property Of Equality)

As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.
