The population of the city has decreased by 15%.

Percentage refers to a way of expressing a number as a fraction of 100, and is often represented by the symbol (%).

To find the percent decrease, we need to determine the difference between the original population and the new population. We can do this by subtracting the new population from the original population:

322,000 - 273,700 = 48,300

This means that the population has decreased by 48,300. To find the percentage decrease, we need to express this as a percentage of the original population. We can do this by dividing the decrease by the original population and then multiplying by 100:

(48,300 / 322,000) x 100 = 15%

The degree of the term with the greatest degree is called the degree of the polynomial.

Here, it is necessary to remember that, by the definition, we can find the "Degree of a polynomial" by identifying the greatest degree of its terms.

The "Leading term" of a polynomial is defined mostly as the term with the highest power of the variable of the polynomial.

The numbers located in front to the variable (those numbers that multiply the variable) are called "Coefficients". The coefficient of the Leading term is known as the "Leading coefficient."

For example, given the following polynomial:

18x² + 2x - 6

You can identify that, in this case:

degree of the polynomial: 2

leading term: 18x²

leading coefficient: 18

The rate constant at 42.4 based on trial E is Value[k = 2.68 X 10^-3] and Units[M-1 s-1]

The rate constant at 42.4 0C is [acetone] initial = 0.2 M, [H+] initial = 0.01 M, so rate= k [acetone] [H+] 5.37 X 10^-6 = k X 0.2 X 0.01, k = 2.68 X 10^-3 , and the order of the reaction is two therefore the unit of the speed constant is M-1 s-1. reaction rate constants and rate laws is a fundamental concept in chemical kinetics, which is the study of the rates and mechanisms of chemical reactions. Reaction rate constants are specific to a particular reaction and are influenced by several factors, including temperature, concentration of reactants and products, the presence of a catalyst, and the activation energy of the reaction. The rate constant is related to the activation energy through the Arrhenius equation, which is given by k = A * exp(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the absolute temperature. The rate law of a chemical reaction describes the mathematical relationship between the rate of the reaction and the concentrations of the reactants. It is determined experimentally by measuring the initial rate of the reaction under different concentrations of the reactants. The rate law is typically expressed as Rate = k[A]^m[B]^n, where k is the rate constant, A and B are the concentrations of reactants, and m and n are the orders of the reaction with respect to A and B, respectively.

(a) The rate at which the amount of water is changing is -1/2.

(b) It will take 20 more minutes to drain the water completely.

(c) The tank was completely full 3 minutes before Kiran arrive.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

(a) Given that,

When Kiran first sees the tank, it contains 12 gallons of water. Four minutes later, the tank contains 10 gallons of water.

Rate at which the amount of water is changing = (10 - 12) / 4 = -2/4 = -1/2 gallons per minute.

(b) Time taken to drain 1/2 gallon = 1 minute

There are 10 gallons of water remaining in the tank.

Time taken to drain 10 gallons of water = (1 ÷ 1/2) × 10 = 20 minutes

It will take 20 more minutes to drain the water completely.

(c) When Kiran arrived, water tank has 12 gallons of water.

Total amount of water in the tank is 15 gallons.

Tank has lost 3 gallons of water before Kiran arrived.

Time taken to drain 3 gallons = (1 ÷ 1/2) × 3 = 6 minutes

So the tank was completely full 3 minutes before Kiran arrive.

Hence the rate is -1/2 gallons per minute.

Answer:

Step-by-step explanation:

The expression for the composition of functions t and s, (t*s)(x), is obtained by substituting the output of s(x) into t(x). So,

(t*s)(x) = t(s(x)) = t(4x) = 3(4x) + 3 = 12x + 3.

The expression for the difference of functions t and s, (t - s)(x), is obtained by subtracting the output of s(x) from t(x). So,

(t - s)(x) = t(x) - s(x) = (3x + 3) - (4x) = -x + 3.

To evaluate (t + s)(-2), we need to add the outputs of t(-2) and s(-2).

t(-2) = 3(-2) + 3 = 3

s(-2) = 4(-2) = -8

So, (t + s)(-2) = t(-2) + s(-2) = 3 + (-8) = -5.

The answer is that there is no probability for this event to happen. To find the probability of getting exactly one red marble or exactly one green marble and not both at the same time, we can use the following steps:

Step 1: Find the number of ways to draw 3 marbles out of 12.

This can be found using the combination formula, which gives:

C(12,3) = 12! / (3! * 9!) = 220

Therefore, there are 220 ways to draw 3 marbles out of 12.

Step 2: Find the number of ways to draw exactly one red marble and two non-red marbles.

There are 3 red marbles, and we need to choose one, so there are C(3,1) = 3 ways to do this. There are 9 non-red marbles, and we need to choose two of them, so there are C(9,2) = 36 ways to do this. Therefore, 3 * 36 = 108 ways to draw exactly one red marble and two non-red marbles.

Step 3: Find the number of ways to draw exactly one green marble and two non-green marbles.

There are 4 green marbles, and we need to choose one, so there are C(4,1) = 4 ways to do this. There are 8 non-green marbles, and we need to choose two of them, so there are C(8,2) = 28 ways to do this. Therefore, there are 4 * 28 = 112 ways to draw exactly one green marble and two non-green marbles.

Step 4: Find the number of ways to draw exactly one red marble and one green marble. There are 3 red marbles and 4 green marbles, and we need to choose one of each, so there are 3 * 4 = 12 ways to do this.

Step 5: Add the results from steps 2, 3, and 4 to get the number of ways to draw marbles that satisfy the given condition.

Total number of ways = 108 + 112 + 12 = 232

Step 6: Find the probability of getting exactly one red marble or one green marble but not both at the same time.

The probability of an event is the number of ways that event can happen divided by the total number of possible outcomes. Therefore, the probability of getting exactly one red marble or exactly one green marble and not both at the same time is:

P = (number of ways to draw marbles that satisfy the given condition) / (total number of ways to draw 3 marbles out of 12 marbles)

P = 232 / 220

P = 1.0545

However, probabilities cannot be greater than 1. Therefore, the answer is that there is no probability for this event to happen.

Step-by-step explanation:

The amount that was paid by Ashley is $ 28.05.  

To find the discount on a given price, multiply the discount that is given by the original price and divide the result by 100.
To find the amount that can be paid by the consumer, subtract the resultant discount from the original price.

Final price of item = Original price - Discount  

Here we have

An item is regularly priced at $33.  

The discount that Ashley bought it = 15% off the regular price.  

The amount that Ashely paid for it = $ 33 - 15% of $ 33  

=> $ 33 - $ (15/100 × 33)

=> $ 33 - $ (0.15 × 33)

=> $ 33 - $ 4.95

The work done in pulling the rope up 10 ft is 864 ft-lbs, calculated by multiplying the rope's weight (72 lbs) by the distance (10 ft) it was lifted.

Work done = Weight x Distance

Work done = 72 lbs x 10 ft

Work done = 720 ft-lbs

Additional work done for weight of rope = Weight of rope x Distance

Additional work done for weight of rope = 90 x 10

Additional work done for weight of rope = 900 ft-lbs

Total work done in pulling the rope up 10 ft = 720 ft-lbs + 900 ft-lbs

Total work done in pulling the rope up 10 ft = 864 ft-lbs

The work done in pulling the rope up 10 ft is calculated by multiplying the weight of the rope (72 lbs) by the distance (10 ft) it was lifted. This gives us a result of 720 ft-lbs. However, since the rope is 90 ft long, we must also take into account the additional weight of the rope beyond the 10 ft that was lifted. So, we multiply the weight of the rope (90 lbs) by the distance (10 ft) to get an additional work done of 900 ft-lbs. Adding the two results together gives us 864 ft-lbs of work done in pulling the rope up 10 ft. This shows that the heavier a rope is, the more work must be done to lift it.

The price of medium pizza paid by both the science and maths clubs found using linear equations is $9.50.

What is meant by equation?

A formula known as an equation uses the equals sign (=) to express how two expressions are equal.

Given,

Cost of 5 large pizzas and 2 medium pizzas paid by the science club = $79.00

Cost of  4 large pizzas and 4 medium pizzas paid by the math club = $86.00

Let the cost of medium pizza = x

Cost of large pizza = y

Now using the above equation we can write two linear equations.

2x + 5y = 79

4x + 4y = 86

Solving the above system of linear equations.

We are making the coefficient of the x variable the same.

Multiplying the first equation by 2.

4x + 10y = 158

4x + 4y = 86

Subtracting the equations.

6y = 72

y = 12

Now substituting in any one equation, we get the value of x.

2x + 5 * 12 = 79

Answer:

9.43 units.

Step-by-step explanation:

To find the distance between two points in a 2D plane, you can use the Pythagorean theorem. The formula for finding the distance between two points (x1, y1) and (x2, y2) is:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values for W and Z:

d = √((8 - 3)^2 + (-2 - 6)^2)

d = √(5^2 + (-8)^2)

d = √(25 + 64)

d = √89

The distance between the points W and Z is approximately 9.43 units.
