The population of a city decreases by 0.9% per year. If this year's population is 338,000, what will next year's population be, to the nearest individual?​

Answers

Answer:

The population will be 334,958.

Step-by-step explanation:

Multiply 338,000 by 0.009 to get the answer. The reason is to multiply by a percentage, you move the decimal two spots to the left. For example, 0.9 -> 0.009.  Another would be 3 -> 0.03.

A cake recipe calls for 2 1/2 cups of flour. If Mrs. Hizon will prepare for 4 2/3 servings of the recipe, how much flour will she need?

At a farm the ratio of cows to horses was 8 : 3. If there were 24 cows at the farm, how many horses were there?

Answers

9 Horses or 24:9

Since there are 24 cows we can do 24/8 and get 3. Then multiply the amount of horses by 3.

3(3) = 9.

Therefore there would be 9 horses.

There are only 6 blue pens, 5 green pens and 8 red pens in a box.
One pen is taken at random from the box.
Write down the probability that this pen is blue.

Answers

Answer:

0.316

Step-by-step explanation:

Probability = (number of outcomes)/(total number of outcomes)

In this case,

the total number of outcomes is 6+5+8 = 19, and

the number of outcomes for getting a blue pen = 6

Hence,

P(blue) = 6/19 = 0.31578947368 ≈ 0.316

Step-by-step explanation:

An inlet pipe on a swimming pool can be used to fill the pool in 15 hours. The drain pipe can be used to empty the pool in 20 hours. If the pool is [tex]\frac{1}{3}[/tex] filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool? Round your answer to two decimal places, if needed.


_____________ hours

Answers

Answer:

40 hours

Step-by-step explanation:

Rate of filling is 1/15Rate of draining is 1/20

If both lines are open the rate of filling is:

1/15 - 1/20 = 4/60 - 3/60 = 1/60 per hour

Since tank is 1/3 full we need to fill the remaining 2/3 of it.

Time required:

2/3 : 1/60 = 2/3*60 = 40 hours

Given f ( x ) = x + 4 and g ( x ) = √ x + 5 , determine the following. Write each answer using interval notation. Domain of f ( g ( x ) ) : Domain of g ( f ( x ) ) :

Answers

Answer:

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

Isaac wants to play miniature golf. Go Golf charges $2.50 for ball and club rental and $4.25 per game. Golf Games charges $3.25 for ball and club rental and $8.50 for two games. For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.​

Answers

The cost would be the same for 47 Go golf and 54 golf games.

What is the Multiplication operation?

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

Given data as:

Charges for Go Golf -

Renting a ball and a club costs $2.50.

$4.25 for one game and

Charges for Golf Games -

3.25 for the rental of a ball and a club

$8.50 for two games

We have to determine the number of games would the cost be the same.

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

For per game = $11.75 / 2 = $5.875

Let the game would be x for  Go golf and

And let game would be y for the golf game

As per the given condition,

6.75 x = 5.875y

27/4 x = 47/8 y

Apply cross multiplication operation,

54x = 47y

x/y = 47 / 54

x = 47

So y = 54.

Hence, the cost would be the same for 47 Go golf and 54 golf games.

The cost would be the same for 47 games at Go Golf and 54 games at Golf Games.

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

Cost per game at Golf Games

= Total charges for 2 games / 2

= $11.75 / 2

= $5.875

Let the number of games be x for Go Golf and y for Golf Games.

As per the given condition,

6.75x = 5.875y

To find the relation between x and y, cross-multiplication can be used:

27/4 x = 47/8 y

54x = 47y

x/y = 47/54

Comparing the value gives

x = 47 and y = 54.

Hence, the cost would be the same for 47 games at Go Golf and 54 games at Golf Games.

What is comparison of two numbers?

Comparison of two numbers, means to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity.

According to the given question

We have a data in which

Number of people who liked action movie = 78

Number of people who liked action movie = 60

Number of people who disliked the action movie = 22

And, number of people who disliked the drama movie = 40

From the given data we conclude, that action movie is liked by more people as compared to drama movie because 78 > 60.

Hence, the action movie is better received by the audience than the drama.

The Astronomical Telescope shop plans to introduce a new model based on the following information: Rent and utilities per period are $ {fixed}; variable cost per unit is $ 217; selling price per unit is $ 305; determine the break-even point in units if rent and utilities are increased to $ 5420.

Answers

Using the profit concept, it is found that the break-even point is of 61.6 units.

Profit is given by revenue subtracted by cost.The break-even point is when the revenue is the same as the cost, which means that the profit is zero.

In this problem:

Variable cost per unit x of $217, fixed cost of $5,420, thus, the cost equation is given by:

[tex]C(x) = 217x + 5420[/tex]

Selling price per unit of $305, thus, the revenue equation is given by:

[tex]R(x) = 305x[/tex]

The break-even point is the value of x for which:

[tex]R(x) = C(x)[/tex]

Then

[tex]305x = 217x + 5420[/tex]

[tex]88x = 5420[/tex]

[tex]x = \frac{5420}{88}[/tex]

[tex]x = 61.6[/tex]

The break-even point is of 61.6 units.

This coaster was designed to accommodate riders from age 4 to adult and features a tall climb hill and several banking turns. Overall, the park has been disappointed in the reception of The Twist, and very few families are riding the coaster this season. After some research, they discovered that park guests think the climb hill is too tall and fast for younger riders. Galaxy Fair Amusement Park has asked a roller coaster design firm to help them redesign The Twist during the coming off season. The quadratic function that represents the current climb hill is () = 0.102 + 3.6 2.4 and the quadratic function that represents the proposed redesign of the climb hill is () = 0.032 + 1.62 6.87. In these functions, the value of x represents the time, in seconds, since the roller coaster train cars have left the station, and the output variable is the height of the roller coaster track, in feet, above the ground. 1.
