A 17-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 10 feet from the base of the building. How high up the wall does the ladder reach?

Answers

Answer:

13.747... meters

Step-by-step explanation:

Refer to image attached~

Let AC represent the length of the ladder.Let BC represent the distance from the base of the ladder from the base of the building.Let AB (x) represent the height of the building.

In this case, the longest side of the triangle formed is AC. Thus, our hypotenuse is AC (17 m).

To determine the height of the building, we need to use pythogoras theorem.

Pythogoras theorem: (Hypotenuse)² = (Side)² + (Side)²

⇒ (17)² = (10)² + (x)²⇒ 289 = 100 + (x)²⇒ 289 - 100 = (x)²⇒ 189 = (x)²

Take square root both sides:

⇒ √189 = √(x)²⇒ x = √189 ≈ 13.747... meters

Answer:

13.75 ft (nearest hundredth)

Step-by-step explanation:

The ladder creates a right triangle with the wall and ground, where:

leg (base) = groundleg (height) = wallhypotenuse = ladder

Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

a = 10 ftc = 17 ft

Substitute the given values into the formula and solve for b:

⇒ 10² + b² = 17²

⇒ b² = 17² - 10²

⇒ b² = 289 - 100

⇒ b² = 189

⇒ b = ±√(189)

As distance is positive, b = √(189) ft only

Therefore, the ladder reaches 13.75 ft (nearest hundredth) up the wall.

30. Tina went to batting cages with $20. She rented a bat for $3. 25 and

paid $3 for each round. What was the greatest number of rounds Tina

could have played?

Answers

Answer:

5

Step-by-step explanation:

Tina started with $20, but had to spend $3.25 on the bat.

$20-$3.25 = $16.75, which is all she has left for rounds.

Each round costs $3.00

$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds

5 rounds X $3.00 per round comes to $15.00

You first need to rearrange your equation to make it equal one variable. So I isolated x which gives me x=-1(y^2-4). You then put the X equation into the first equation. Which gives (-y^2+4)^2-y^2=16. The answer when you solve for y is 0. You then substitute y in the second equation. Which gives 0=-x+4 then solve for x. The answer being x=4 and y=0
