Answer:

4 hours

Step-by-step explanation:

Decorations and refreshments already cost $172, so subtract 172 from 380

380 = 172 = 208

The band charges a $100 flat fee, so subtract 100 from 208

202 - 100 = 108

We have $102 remaining

To find how many hours the band can play, divide 108 by 25

102 ÷ 25 = 4.32

You can't buy 0.32 hours, so round that 4.32 down to 4

The equation could be used to solve for charles' rate if it is represented by x is 2x=54.

In the given question wehave to find the equation could be used to solve for charles' rate if it is represented by x.

Bill riding a bicycle at an average rate of 9 mph.

Charles' rate is x.

So the relative rate = x−9 mph

Distance traveled by Bill in 4 hours = 9*4 =36 mph

Charles' overtook Bill in 2 hours. So

Relative Rate = Distance/Time

x−9=36/2

Multiply by 2 on both side. We get

2(x−9)=36

Simplifying

2x−18=36

Add 18 on both side, we get

2x=36+18

2x=54

Hence, the equation could be used to solve for charles' rate if it is represented by x is 2x=54.

Answer: 151,200 combinations

Step-by-step explanation:

So we want to order the numbers 1, 2, .... , 9 in a:

\(\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]\)

such that the sum in each row is an odd number.

if we add 3 odd numbers we have an odd number.

if we add 2 even numbers, and an od number, we have an odd number.

where the rows are in this case (1, 2, 3), (4,5,6) and (7, 8, 9)

We have 4 even numbers and 5 odd numbers, so one combination can be:

\(\left[\begin{array}{ccc}1&5&3\\4&7&6\\2&8&9\end{array}\right]\)

Now, we for this option we can:

permute the numbers in each row: c =3*2*1 options per row and permute the rows, also c = 3*2*1

So only for this combination we have: P = (3*2)^4 possible ways of writing it.

Now, let's find the different combinations of numbers, so you can expect that we will find a lot of combinations, now let's construct them:

Suppose that in the first row we have two even numbers and 1 odd, then for the first even number we have 4 options, for the second 3 options, and for the odd number 5 options, so we have 4*3*5 combinations.

For the second row we also want two even numbers and one odd.

For the first even number we have 2 options, for the second one, and for the odd number we have 4 options, so we have 4*2*1 combinations.

In the last row we want the other 3 odd numbers, so we have 3*2*1 combinations, this adds to:

C = (4*3*5)*(3*2*1)*(4*2*1) = 2880 combinations.

If we add the fact that the rows can interchange positions, we have other 3*2*1 combinations:

C = 2880*3*2 = 16,800 and if now we add the fact that the numbers in the first two rows can permute (it is not the same (2, 4, 5) than (2, 5, 4) or (4, 2, 5)) (this happens because in these two rows we have different types of numbers, while in the third one the permutations are already included)

So the thing that can change in the first two rows is the position of the odd number, can be first, second or third, so we have other 3 permutations for the two first rows:

C = 16,800*3*3 = 151,200  which is the total number of  different combinations.

Aldosterone is a hormone produced by the adrenal gland that plays an important role in regulating electrolyte and water balance in the body. It acts on the cells of the distal tubules and collecting ducts of the kidneys to increase the reabsorption of sodium ions and the secretion of potassium ions.

This helps to increase blood volume and blood pressure by retaining more sodium and water in the body while getting rid of excess potassium. Aldosterone release is regulated by the renin-angiotensin-aldosterone system, which is activated in response to low blood pressure or low sodium levels in the blood.

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

Answer:

Step-by-step explanation:

5% of 50000 is 2500

(50000 * 0.05 = 2500)

50000 + 2500 = 52500

another way to do it is just multiply 50000 by 1.05 (105%)

To find the number of three-letter initials with none of the letters repeated, we need to consider the number of choices for each position in the initials.

To determine the number of three-letter initials with none of the letters repeated, we can analyze each position in the initials. For the first letter, we have 26 choices since there are 26 letters in the English alphabet.

After selecting the first letter, for the second letter, we have 25 choices remaining since we cannot repeat the letter used in the first position. Similarly, for the third letter, we have 24 choices remaining since we cannot repeat either of the previous letters.

Therefore, the total number of three-letter initials with none of the letters repeated can be found by multiplying the number of choices for each position: 26 * 25 * 24 = 15,600. Hence, there are 15,600 different three-letter initials that people can have if none of the letters are repeated.

The volume of the part of the cone that is filled with sand is 2/9 times the total volume of the cone.

To do this, we need to first determine the total volume of the cone. The formula for the volume of a cone is:

V = 1/3 x π x r² x h

Where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is a mathematical constant (approximately equal to 3.14).

Since we know that the paper cup is cone-shaped, we can assume that it has a circular base. Let's say that the radius of the base of the cone is r and the height of the cone is h.

The total volume of the cone can be calculated using the formula above:

V = 1/3 x π x r² x h

Now we need to determine the volume of the part of the cone that is filled with sand. We know that the cup is 2/3 full of sand, so the volume of sand in the cup is 2/3 of the total volume of the cup. We can express this as:

V = 2/3 x V

We can substitute the formula for V into this equation to get:

V  = 2/3 x (1/3 x π x r² x h)

Simplifying this equation, we get:

V = 2/9 x π x r² x h

The last year value of the house will be $230,000.

Step-by-step explanation:

GIVEN: Decrease in house price = 20%

            Current house price = $184,000

TO FIND: Value of the house last year

SOLUTION:

If the value of the house decreased by 20% during last year, this means the value of the house this year is 80% of last year's value.

Let the value of the house last year be 'x'.

If the value of the house today is  $184,000, then:

                           \(80/100 * x = 184,000\\\\0.8x = 184,000\\\\x = 184,000/0.8\\\\x = 230,000\)

Therefore, the last year value of the house will be $230,000.

Answer:

Value of x is used to consider unknown value.

Step-by-step explanation:

Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable.

On average there is a predicted increase of 19.0 ppm in concentration of zinc for every increase of 1 ppm in concentration of lead found in the fish.

A variable's value can be predicted using linear regression analysis based on the value of another variable. The dependent variable is the one you want to be able to forecast. The independent variable is the one you're using to make a prediction about the value of the other variable. More specifically, the nature and degree of the correlation between a dependent variable and a number of different independent variables are assessed using linear regression. It aids in the creation of models for making predictions, such as projecting the stock price of a corporation.

Step-by-step explanation:

a) By substituting t = 3tan(θ), we can rewrite this term as 9 + (3tan(θ))^2 = 9 + 9tan^2(θ) = 9(1 + tan^2(θ)), b) ∫(1/9tan^2(θ))(3sec(θ)) dθ = ∫(1/3tan^2(θ))(sec(θ)) dθ, c) the integral in terms of t is:  ∫(1/27 - t^2/9)(sec(θ)) dθ + C.

(a) According to the method of trigonometric substitution, the appropriate substitution for this integral is t = 3tan(θ).

To determine the appropriate substitution, we consider the term under the square root: 9 + t^2. By substituting t = 3tan(θ), we can rewrite this term as 9 + (3tan(θ))^2 = 9 + 9tan^2(θ) = 9(1 + tan^2(θ)).

This substitution allows us to simplify the integral and express it solely in terms of θ.

(b) Using the substitution t = 3tan(θ), we can rewrite the given integral in terms of θ as:

∫(1/t^2)√(9 + t^2) dt = ∫(1/(9tan^2(θ)))√(9(1 + tan^2(θ))) (sec^2(θ)) dθ.

Simplifying further, we get:

∫(1/9tan^2(θ))(3sec(θ)) dθ = ∫(1/3tan^2(θ))(sec(θ)) dθ.

(c) To evaluate the integral in part (b), we need to express the answer in terms of t using a triangle.

Let's consider a right triangle where the angle θ is one of the acute angles. We have t = 3tan(θ), so we can set up the triangle as follows:

     |\

     | \

     |   \

   3|     \ t

     |       \

     |____\

      9

Using the Pythagorean theorem, we can find the third side of the triangle:

9^2 + t^2 = 3^2tan^2(θ) + t^2 = 9tan^2(θ) + t^2.

Rearranging this equation, we get:

t^2 = 9^2 - 9tan^2(θ).

Now, substituting this expression back into the integral, we have:

∫(1/3tan^2(θ))(sec(θ)) dθ = ∫(1/3(9^2 - t^2))(sec(θ)) dθ.

Therefore, the integral in terms of t is:

∫(1/27 - t^2/9)(sec(θ)) dθ + C.

There are six possible outcomes in the outcomes space. Let us solve each part of the question.How many possible outcomes are there in the outcomes space?The possible outcomes in the outcomes space for the given problem is calculated by multiplying the number of outcomes of the first roll by the number of outcomes of the second roll.Number of possible outcomes of each roll

= 6 (as there are six faces on a dice)Total possible outcomes in the outcomes space

= 6 × 6

= 36So, there are 36 possible outcomes in the outcomes space.How many elements are in the event of getting different numbers without repetitions?In this case, the two rolls are independent. This means the first roll doesn't affect the second roll. Thus, all possible outcomes with different numbers are 6 × 5

= 30. So, there are 30 elements in the event of getting different numbers without repetitions.How many elements are in the event of getting different numbers without repetitions but the second number must be a 4?In this case, we can have any one of the six numbers in the first roll. Then, only one number 4 is left for the second roll. Thus, there are 6 possible outcomes where the second number is a 4. Hence, there are 6 elements in the event of getting different numbers without repetitions but the second number must be a 4.The summary of the results is as follows:How many possible outcomes are there in the outcomes space.- 36 How many elements are in the event of getting different numbers without repetitions. - 30 How many elements are in the event of getting different numbers without repetitions but the second number must be a 4? - 6
