The plane was at 28200 feet then it desended 3500 feet then it was at 24700 feet.

The factor by which the population will grow in 40 years is 4.

The doubling time of a population is the amount of time it takes for the population to double. In this case, the population has a doubling time of 20 years. This means that if the population is P0 now, then in 20 years, the population will be 2P0. After 40 years, the population will double again and will be 4P0. This is because the population doubles every 20 years.

Therefore, in 40 years, the population will double twice. The factor by which the population will grow is the final population divided by the initial population. The initial population is P0 and the final population is 4P0. Therefore, the factor by which the population will grow in 40 years is 4.

The doubling time is the amount of time it takes for the population to double. If a population has a doubling time of 20 years, this means that the population will double every 20 years. If the population is P0 now, in 20 years it will be 2P0, and in 40 years it will be 4P0.

The factor by which the population will grow is the final population divided by the initial population. Therefore, if the initial population is P0 and the final population is 4P0, then the factor by which the population will grow in 40 years is 4.

If a population has a doubling time of 20 years, then it will double every 20 years. After 40 years, the population will double twice, and will be 4 times the initial population.

Step-by-step explanation:

x=0

Answer:

x = -7

Step-by-step explanation:

First, you must distribute the -3 to the numbers in the parenthesis. You will get -18x - 6. the problem is now 113 = x - 18x - 6. With inverse operations this will become 119 = -17x. Divide 119 by -17 and you will get -7.  x = -7.

Answer:

x = -7

Step-by-step explanation:

113 = x - 3(6x + 2)

113 = x - 18x - 6

x - 18x = 113 + 6

-17x = 119

x = -7

Answer:

Initiation fee= $50

Monthly charge= $25

Step-by-step explanation:

Giving the following information:

For 2 months it is $100 and for 6 months it is $200.

To calculate the fixed cost (initiation fee) and the variable cost per month, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (200 - 100) / (6 - 2)

Variable cost per unit= $25

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 200 - (25*6)

Fixed costs= $50

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 100 - (25*2)

Fixed costs= $50

Initiation fee= $50

Monthly charge= $25

Probability that both of them have the secret decoder ring is 0.032

Probability is a way to gauge how likely something is to happen. Several things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

11 of the 59 boxes on the shelf have a secret decoder ring

48 boxes on the shelf contain a different gift

two cereal boxes are randomly selected from the shelf to purchase

the probability that 1st  have the secret decoder ring = 11/59

the probability that 2nd have the secret decoder ring = 10/58

probability that both of them have the secret decoder ring.

Answer:

C. 8485.3 meters

Step-by-step explanation:

Think of the sailboat’s path as a 45-45-90 right triangle.

The hypotenuse is the 6000 meter distance.

In this way the leg will be the hypotenuse divided by √2.

So 6000/√2 or 4242.64 meters.

Remember that the sailboat has to turn and head back toward its goal and travel another 4242.64 meters.

Thus, your answer is 4242.64 x 2 = 8485.28 meters or 8485.3 meters.

In this exercise we have to use the knowledge of triangles to calculate the distance that one of the sides has:

Letter C

Some information given in the statement about the triangle:

So performing the calculation we have:

\(6000\sqrt{2}=4242.64 \\4242.64 * 2 = 8485.28\)

Using the information given in both table and graph, Gloria's time is faster by 2.5 minutes

Richard :

Average speed = (5.2 - 4.6) / (25 - 20) = 0.12 km/min

Time taken = distance/ speed

Richard's distance to be covered = 10-2.2 = 7.8km

Hence,

Gloria's average speed :

Average speed = (4 - 3.2)/(25 - 20) = 0.16 km/hr

Gloria's distance to be covered = 10km

Hence,

Time difference = 65 - 62.5 = 2.5 minutes

The regular price of a ticket to the game was $204.00.

We can use algebra to solve the problem. Let x be the regular price of a ticket to the game.

We know that the group rate saved Mason $5.75 per ticket, so the regular price of a ticket is x + $5.75.

We know that Mason bought 16 tickets and paid a total of $296.00, so we can set up the following equation:

x + $5.75 = (x + $5.75) * 16 = 16x + $92

So the regular price of a ticket is x = $296.00 - $92 = $204.00

Therefore, the regular price of a ticket to the game was $204.00.

Answer:

1. No

2. Yes

3. No

4. Yes

Step-by-step explanation:

x is equal to the number of miles, so it can't be the amount in dollars.

25 is the fixed amount because it does not change in the equation.

0.35 is not the fixed amount because it changes based on x.

f(x) is the total amount because that's what the equation is equal to.

Step-by-step explanation:

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

we see that the visible 7 numbers have a range of 50-17 = 33.

that means that x has to make sure that the range really is 69.

so, we have indeed 2 choices : x can be the lowest value (with a difference of 69 to the highest value, 50), or x can be the highest value (with a difference of 69 to the lowest value, 17).

x as the lowest value :

x = 50 - 69 = -19

x as the highest value :

x = 17 + 69 = 86

The g(x) function is an odd function and h(x) is neither odd nor even.

What are odd and even functions?

Odd function - The function that changes it's value to negation of given                            function after putting (-)variable.

i.e. f(-x) = -f(x)

Even function - The function that doesn't changes it's value to negation of given function after putting (-)variable.

i.e. f(-x) = f(x)

In given functions:

g(x)=5x

then, g(-x)= 5(-x)

                = -5x

                = -g(x)

So, g(x) is an odd function.

h(x)=5x^2- 6x^23

then, h(-x) = 5(-x)^2 - 6(-x)^23

                 = 5x^2 + 6x^23

As, it's neither equal to h(x) nor h(-x).

Hence, find the right answer.
