Answer:
Total 17 high rate filters are required
Step-by-step explanation:
Given -
Rate of filtration of slow sand filters = 10 million gallons/acre-day
Total million gallons of water filtered per day = 10 million gallons/acre-day * 15 acres
= 150 Million gallons per day
Rate of filtration of high rate filters = 6 gpm/ft2
Area of one high rate filter = 1,000 ft2
Volume of water filtered by 1 high rate filter is 6 gpm/ft2 *1,000 ft2 = 6000 gallons per minute = 8640000 gallon per day
Number of filters required = 150 million gallons per day /8640000 gallon per day
150 * 10^6/8640000
17
Total 17 high rate filters are required

After a hailstorm, a large car dealership wants to determine the proportion of cars that have damage. The service
department randomly selects 50 cars on the dealership lot, examines them, and finds that 11 cars have damage.
They want to construct a 99% confidence interval for the true proportion of cars with damage from the storm. Are
the conditions for inference met?
O Yes, the conditions for inference are met.
O No, the 10% condition is not met.
No, the randomness condition is not met.
No, the Large Counts Condition is not met.
Answer:
A, yes the conditions for inference are met

in an inverse variation, x=2 when y=-4. what is the value of y when x=16
Answer:
y = -1/2
Step-by-step explanation:
Use the inverse variation equation, y = [tex]\frac{k}{x}[/tex]
Plug in 2 as x and -4 as y, then solve for k:
y = [tex]\frac{k}{x}[/tex]
-4 = [tex]\frac{k}{2}[/tex]
-8 = k
So, the equation is y = [tex]\frac{-8}{x}[/tex]
Plug in 16 as x and solve for y:
y = [tex]\frac{-8}{x}[/tex]
y = [tex]\frac{-8}{16}[/tex]
y = -1/2
So, when x = 16, y = -1/2

Step-by-step explanation:
Find the value of k.
Answer:
k = - 3
Step-by-step explanation:
g(x) is really a disguise of f(x). What you have done is move 3 units down. (Just look at the minimum point of f(x) which is 0,0) The minimum point has gone down to 0,-3
So the value of k must be - 3
What are the values for q that will make the equation true |4q+12|=4
Hi there! Solving the absolute value equation is like solving a quadratic equation.
[tex] \large{ |x| = a \longrightarrow x = \pm a}[/tex]
[tex] \large{ |x| = \begin{cases} x \: \: \: (x \geqslant 0) \\ - x \: \: \: (x < 0) \end{cases}}[/tex]
From the absolute equation:
[tex] \large{ |4q + 12| = 4}[/tex]
Cancel the absolute symbol and write plus-minus of 4.
[tex] \large{4q + 12 = \pm 4}[/tex]
Solve the equation for q-term.
[tex] \large{4q = \begin{cases} 4 - 12 \\ - 4 - 12 \end{cases}} \\ \large{4q = \begin{cases} - 8 \\ - 16 \end{cases}} \\ \large{q = \begin{cases} - \frac{8}{4} \\ - \frac{16}{4} \end{cases}} \\ \large{q = \begin{cases} - 2 \\ - 4 \end{cases}}[/tex]
Hence, the value of q are -2,-4
Answer
q = -2,-4This is (Worth 10 points)

2) What is the volume of a basketball that has a diameter of 15 inches?
What should be done to solve the following equation? d - 5 = 3
Answer:
d=8
Step-by-step explanation:
Firstly you need to get d by itself. To get d by itself you need to get 5 onto the other side. To do that you need to add 5 to 3 (because adding is the opposite of addition). Therefore you will get 8! So d = 8
Answer:
add 5 both sides making it
d=5+3
solve 5+3
=8
d=8!!!What is the volume of the prison below?
Answer:
3 1/2
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply l*w*h.
We just have to multiply 1 3/4 by 2!
*This is because the 1 doesn't give you anything.*
That equals 3 1/2!

You are jumping rope at a rate of 15 jumps every 24 seconds. At this rate, how long will it take you to jump 90 times?
Answer:
144 seconds
Step-by-step explanation:
divide 90 by 15 to get 6
if you are jumping in sets of 15, that means you need to jump 6 sets to get to a total of 90 jumps total. if every set of 15 jumps takes 24 seconds that means that 6 sets will take 144 seconds. 6 x 24 = 144

Tell whether the triangle with each set of side lengths is a right triangle.
(See picture)
Answer:
Right Triangles:
(5.1, 6.8, 8.5) and (12.5, 30, 32.5)
Not Right Triangles:
(2.2, 4.5, 6.7) and (4.7, 8.6, 10.7)
Step-by-step explanation:
I solved by using the pythagorean theorem (a^2+b^2=c^2)
Plug the side lengths in, the largest side length is always c. If the equation comes out true, it is a right triangle.
