Help plsss I need to pass math

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

Answer:

62

Step-by-step explanation:

let there be X people in the beginning

so

X-18+21=65

X+3=65

X=65-3

X=62

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.

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.

Answer:

Let's define.

L = rate at which the large pump fills the pool.

S = rate at which the small pump can fill the pool.

We have two relations:

"Two large and 1 small pump can fill a swimming pool in 4 hours."

(2*L + S)*4h = 1

"One large and 3 small pumps can also fill the same swimming pool in 4 hours."

(L + 3*S)4h = 1

Then we have the system of equations:

(2*L + S)*4h = 1

(L + 3*S)4h = 1

To solve this system, we need to isolate one of the variables in one of the equations, i will isolate S in the first equation:

S = 1/4h - 2*L

Now we can replace that in the second equation:

(L + 3*(1/4h - 2*L))4h = 1

L + (3/4h) - 6*L = 1/4h

-5*L = 1/4h - 3/4h = -2/4h

L = (2/4h)*(1/5) = (2/20h) = 1/10h

This means that one large pump needs 10 hours to fill one pool.

With this, we can find the value of S:

S = 1/4h - 2*L = 1/4h - 2/10h = 5/20h - 4/20h = 1/20h

This means that a small pump needs 20 hours to fill a pool.

Now we can answer:

How many hours will it take 4 large and 4 small pumps to fill the swimming pool?

We need to solve the equation:

(4*(1/10h) + 4*(1/20h))*T = 1

We need to find the value of T.

T = 1/((4*(1/10h) + 4*(1/20h)) = 1.67 hours.

This means that 4 large and 4 small pumps need 1.67 hours to fill a pool.

Answer:

x = -2, x = 6

Step-by-step explanation:

18 = 3|x - 2| + 6

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.
