City worker drain a community pool that contains 403,920 gallons of water. The pump they use removes water at a rate of 40 cubic feet per minute. One cubic foot of water contains 7.48 gallons how long in hours will it take to remove all the water from the pool
Answer:
22.5 hours
Step-by-step explanation:
One cubic foot of water contains 7.48 gallons, so 40 cubic feet of water would equal 7.48 × 40, or 299.2 gallons. So the pumping rate is 299.2 gallons per minute. Multiplying 299.2 by 60, we have
299.2 × 60, or 17952 gallons per hour. Finally, divide 403,920 by 17,952 to find the number of hours to remove all the water: 403,920 ÷ 17,952 = 22.5 hours

Help please
Answer:
Yo Rick Astley
Step-by-step explanation:
y ∝ 1 √ x
y = k (1 √ x)
y = 7 when x = 36
7 = k ( 1 / √36)
7 = k (1/6)
k= 7 × 6
k = 42
If x = 4 then,
y = 42 ( 1/√4)
y = 42 ( 1/2)

If A = (-1,-3) and B = (11,-8), what is the length of AB?
A. 14 units
B. 13 units
C. 11 units
D. 12 units
SUBMIT
A
Answer:
B
Step-by-step explanation:
Use the distance formula:
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
Let (-1,-3) be \(x_1\) and \(y_1\), while (11,-8) be \(x_2\) and \(y_2\).
Thus:
\(d=\sqrt{((11)-(-1))^2+((-8)-(-3))^2\)
\(d=\sqrt{12^2+(-5)^2}\)
\(d=\sqrt{144+25} =\sqrt{169} =13\)

THE EXPOSURE COEFFICIENT, b, IS DEFINED AS: Select one: a. Var(S)/Cov(P,S) b. Cov(P,S)/Nar(S) c. Cov(PS)Nar(P) d. Cov(P,S)/Cov(S)
"The correct option is D." The definition of the exposure coefficient is Cov(P,S)/Cov(S).
The exposure coefficient is a measure that quantifies the relationship between two variables, P and S. It is commonly used in statistics and finance to understand the sensitivity or responsiveness of one variable (S) to changes in another variable (P).
Cov(P,S) represents the covariance between the variables P and S, which measures the degree to which they vary together. Cov(S) represents the covariance of variable S with itself, which is essentially the variance of S.
By dividing the covariance between P and S (Cov(P,S)) by the covariance of S (Cov(S)), we obtain the exposure coefficient, b. This ratio provides insights into how changes in P are associated with changes in S, taking into account the variability of S itself.

Gabriel is investigating the forces that result from contact. All of the following are types of contact forces, except which of the following? a.Electrostatic force, b.Air resistance, c.Spring compression, d.Friction force
The type of contact force that is not included in the given options is the electrostatic force. The other three options—air resistance, spring compression, and friction force—are examples of contact forces.
Contact forces arise when two objects physically interact with each other. They can be categorized into various types based on the nature of the interaction. In this case, the given options include air resistance, spring compression, and friction force, which are all examples of contact forces.
Air resistance, also known as drag, occurs when an object moves through a fluid medium, such as air or water. It opposes the motion of the object and is directly proportional to the object's velocity.
Spring compression is a contact force that occurs when an external force compresses or stretches a spring. The spring exerts an equal and opposite force in response to maintain its equilibrium position.
Friction force is another type of contact force that opposes the relative motion or tendency of motion between two surfaces in contact. It can either be static friction, which prevents initial motion, or kinetic friction, which opposes motion that is already occurring.
Unlike the other three options, which involve physical contact between objects, electrostatic force is the interaction between electrically charged particles without direct contact. It is a non-contact force that can attract or repel charged objects based on their charges.

Convert the map scale to a unit rate. How many inches represent one mile? Show your work. Interpret the
meaning of the unit rate.
3/10 in.=7/8mi.
Answer:
Step-by-step explanation:
we want this to be in one inch units. we are told 3/10 of an inch is 7/8 of a mile. so use the reciprocal of 3/10 or 10/3 to get to one.
7/8* 10/3 = 70/24 mile is equal to one inch.
Now figure out how much 70/24th miles is.
2.91666666 miles = 1 inch
3. Calculate the Reynolds number, Re for water flow in a circular pipe. The diameter of the pipe is 50 mm, the density of water is 998 kg/m", the volumetric oil flowrate is 720 L/min, and the dynamic viscosity of water is 1.2 centipoise
The Reynolds number (Re) for water flow in the circular pipe is approximately 160,920.
The Reynolds number (Re) is calculated using the formula:
Re = (density * velocity * diameter) / viscosity
Given:
Diameter of the pipe = 50 mm = 0.05 m
Density of water = 998 kg/m^3
Volumetric flow rate of water = 720 L/min = 0.012 m^3/s
Dynamic viscosity of water = 1.2 centipoise = 0.0012 kg/(m·s)
First, we need to convert the volumetric flow rate from L/min to m^3/s:
Volumetric flow rate = 720 L/min * (1/1000) m^3/L * (1/60) min/s = 0.012 m^3/s
Now we can calculate the velocity:
Velocity = Volumetric flow rate / Cross-sectional area
Cross-sectional area = π * (diameter/2)^2
Velocity = 0.012 m^3/s / (π * (0.05/2)^2) = 3.83 m/s
Finally, we can calculate the Reynolds number:
Re = (density * velocity * diameter) / viscosity
Re = (998 kg/m^3 * 3.83 m/s * 0.05 m) / (0.0012 kg/(m·s)) = 160,920.

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a queen and then without replacement a face card?express your answer as a fraction or decimal rounded to four decimal places
In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
total cards = 52
Step 02:
probability:
p(event) = favorable outcomes / total outcomes
total cards = 52
total queens = 4
total face cards = 12
first event (queen):
p(queen) = 4 / 52
second event (face card):
without replacement
p(face card) = 11 / 51
total probability (queen and face card):
\(p(queen\text{ }and\text{ }face\text{ }card)=\frac{4}{52}*\frac{11}{51}=\frac{44}{2652}=0.0166\)The answer is:
p (queen and face card) = 0.0166
Find the probability of
drawing a spade, then
drawing a face card out of a
deck
The likelihood of pulling a spade followed by a face card from a deck is 3/52, or roughly 0.0588. (rounded to four decimal places).
What is the probability?The probability of drawing a spade from a deck of 52 cards is 13/52, or 1/4, since there are 13 spades in the deck.
Once a spade has been drawn and not returned to the deck, there are now 51 cards left in the deck, of which 12 are face cards (the Jack, Queen, and King of each suit). Therefore, the probability of drawing a face card given that a spade has already been drawn is 12/51.
To find the probability of both events happening together (drawing a spade and then a face card), we can multiply the probabilities of each event:
P(drawing a spade, then drawing a face card) = P(drawing a spade) x P(drawing a face card given that a spade has been drawn)
= (1/4) x (12/51)
= 3/52
Therefore, the probability of drawing a spade, then drawing a face card out of a deck is \(3/52\) , or approximately \(0.0588\) (rounded to four decimal places).

52 = x2 + 32 – 2(3)(x)cos(140°)
x2 = 52 + 32 – 2(5)(3)cos(100’)
x2 = 52 + 32 – 2(5)(3)cos(140°)
Answer:
D. x2 = 52 + 32 – 2(5)(3)cos(140°)
Step-by-step explanation:
The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.
The distance, x, from the starting point is;
From the cos law ;
x² = a² +b²-2ab cosΘ

Plastic milk contsiners arr produced by a machine that runs continuously. If 5 percent of the containers produced are nonconforming, determine the probability that out of four containers chosen at random, less than two are nonconforming.
The probability that out of four containers chosen at random, less than two are nonconforming is 0.986.
Given that the plastic milk containers are produced by a machine that runs continuously.
If 5 percent of the containers produced are nonconforming, we need to determine the probability that out of four containers chosen at random, less than two are non-conforming.
Probability of nonconforming = 5% = 0.05
Probability of a conforming container = 1 - Probability of nonconforming = 1 - 0.05 = 0.95
Let X be the number of nonconforming containers out of four containers chosen at random. Since there are only two outcomes (conforming and nonconforming), we can model the situation with a binomial distribution.
The probability mass function of a binomial distribution is given by:
P(X = x) = nCx * p^x * (1-p)^(n-x)
Where nCx = n! / (x! * (n-x)!) is the binomial coefficient.
Therefore, we can write the probability of less than two nonconforming containers as:
P(X < 2) = P(X = 0) + P(X = 1)
P(X = 0) = 4C0 * (0.05)^0 * (0.95)^4 = 0.8145
P(X = 1) = 4C1 * (0.05)^1 * (0.95)^3 = 0.1715
P(X < 2) = 0.8145 + 0.1715 = 0.986
Therefore, the probability that out of four containers chosen at random, less than two are nonconforming is 0.986.

The graph shows f(x). The absolute value function g(x) is described in the table. The graph shows a v-shaped graph, labeled f of x, with a vertex at 0 comma 2, a point at negative 1 comma 3, and a point at 1 comma 3. x g(x) −1 5 0 4 1 3 2 2 3 3 If g(x) = f(x + k), what is the value of k? k = −2 k is equal to negative one half k is equal to one half k = 2
Where the above graph and conditions are given, the value of k that satisfies g(x) = f(x+k) is k = -2.
What is the explanation for the above response?We can determine the value of k by using the given relationship between g(x) and f(x+k).
If g(x) = f(x + k), then we can substitute the given values of x in g(x) to get:
g(-1) = f(-1 + k) --> 5 = f(-1 + k)
g(0) = f(0 + k) --> 4 = f(k)
g(1) = f(1 + k) --> 3 = f(1 + k)
g(2) = f(2 + k) --> 2 = f(2 + k)
g(3) = f(3 + k) --> 3 = f(3 + k)
We know that f(x) is a v-shaped graph with a vertex at (0,2) and points at (-1,3) and (1,3). Therefore, we can conclude that f(k) = 4, which means that k is the x-coordinate of the vertex of f(x) shifted to the left or right.
Since the vertex of f(x) is at (0,2), and the x-coordinate of the vertex of f(x+k) is at k, we have:
k = 0 --> vertex of f(x+k) is at (0,2)
k = -1 --> vertex of f(x+k) is at (-1,2)
k = 1 --> vertex of f(x+k) is at (1,2)
k = 2 --> vertex of f(x+k) is at (2,2)
Therefore, the value of k that satisfies g(x) = f(x+k) is k = -2.
