Answer:
i believe x is 12.
Step-by-step explanation:
three times three is nine, so you multiply four by three to get 12. you can also check your answer by dividing 12 by three and 9 by three to get 4,3 so the answer is correct.
Answer:
x=12
Step-by-step explanation:
How I solved this is by making a proportion with fractions In your first fraction the numerator is 4 and your denominator is 3. In your second fraction your numerator is x and your denominator is 9. You would multiply 4 times 9 then divide by 3 to get your answer. I hope this is correct and good luck!!

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.
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 distanceUsing 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.

Two large and 1 small pump can fill a swimming pool in 4 hours. One large and 3 small pumps can also fill the same swimming pool in 4 hours. How many hours will it take 4 large and 4 small pumps to fill the swimming pool? Please help me answer I'm in 5th grade and this is so hard.
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.

The measure of the exterior angle of the triangle is
Answer:
139°
Step-by-step explanation:
By definition, the measure of an exterior angle is the sum of the two interior angles not supplementary to the exterior one.
Here, we see that the two interior angles not supplementary to ∠2 are valued at 75° and 64°, so our exterior angle is the sum of these:
∠2 = 75 + 64 = 139°

Mr. Frank bought a car that cost $33,000 dollars. The car depreciates approximately 12% of
its value each year. Which equation represents the value, v, of the car after t years?
Answer:
v = 33,000 - 3960t
Step-by-step explanation:
3960 is equivalent to 12 percent of 33,000. The original value of the car, 33,000, then decreases by 3960 dollars times t, the number of years.
Select all ratios equivalent to 3:5.

Given the function f(x) = 3|x – 2| + 6, for what values of x is f(x) = 18?
x = –2, x = –8
x = –2, x = –6
x = –2, x = 6
x = –2, x = 8
Answer:
x = -2, x = 6
Step-by-step explanation:
18 = 3|x - 2| + 6
12 = 3|x - 2|
4 = |x - 2|
4 = x - 2 and -4 = x - 2
x = 6 and x = -2
Answer:
C
Step-by-step explanation:
x = -2 x = 6
