This one has two parts, first we have to find out the speed to drive 660 miles in 12 hours.  Divide 660 by 12 to get the speed of 55 miles per hour, that is your rate for the next part.

Next we need to find out how long it will take to drive 495 miles at the same pace of 55 mph.

Do the same thing 495/55.  That will give you your final answer.

495/55= 9

It will take him 9 hours to drive 495 miles at a rate of 55 mph.

Final answer:

Greg drives at a speed of 55 miles per hour. To drive 495 miles at this rate, it would take him 9 hours.

Explanation:

The question asks how long it would take Greg to drive 495 miles if he drove 660 miles in 12 hours. To solve this, we need to find his driving speed and then calculate how long it would take to drive 495 miles at that same speed.

First, we find the speed by dividing the distance traveled by the time:

Speed = Distance ÷ Time

Speed = 660 miles ÷ 12 hours = 55 miles per hour

Now that we know Greg drives at a speed of 55 miles per hour, we can calculate the time it would take him to drive 495 miles:

Time = Distance ÷ Speed

Time = 495 miles ÷ 55 miles per hour = 9 hours

Therefore, it would take Greg 9 hours to drive 495 miles at the same rate of speed.

To find the total snow fall you would multiply the amount of snow per hour by the number of hours it snows:

Total = 3/4 inch per hour x hours: Total = 3/4h

h = 12 hours:

Total = 3/4(12) = 9 inches total.

Answer: Speed of local bus is 50 mph  and speed of express bus is 75 mph

Step-by-step explanation:

let say speed of local bus = x

so speed of express bus = x + 25

Distance = Speed × Time

Distance traveled by local bus  = x × 10.2 = 10.2x

Distance traveled by express bus = (x + 25) × 6.8

since Distance traveled by local bus is same as Distance traveled by express bus

⇒10.2x = (x + 25) × 6.8

⇒ 10.2x = 6.8x + 170

⇒ 10.2x - 6.8x = 170

⇒ x = 170/3.4 = 50

So Speed of local bus = x = 50 mph

and Speed of express bus =  x + 25 = 50 + 25 = 75 mph

Final answer:

The speed of the local bus is 50 mph and the speed of the express bus is 75 mph.

Explanation:

Let's define the speed of the local bus as 'x'.

The speed of the express bus is 25 mph faster than the speed of the local bus, so the speed of the express bus can be represented as 'x + 25'.

We know that the time taken by the express bus is 6.8 hours and the time taken by the local bus is 10.2 hours.

Using the formula Speed = Distance / Time, we can set up two equations:

Distance / 6.8 = x + 25  (equation 1)

Distance / 10.2 = x  (equation 2)

Since the distance is the same for both buses (Sacramento to San Diego), we can equate the distances in equation 1 and equation 2:

x + 25 = (10.2/6.8) * x

x + 25 = 1.5x

0.5x = 25

x = 50

Substituting the value of x in equation 1, we can find the speed of the express bus:

Distance / 6.8 = (50 + 25)

Distance = 6.8 * 75

Speed of the express bus = Distance / 6.8 = 75

So, the speed of the local bus is 50 mph and the speed of the express bus is 75 mph.

Answer: The theoretical probability of choosing a tile with letter P =0.18

Step-by-step explanation:

Given word = MISSISSIPPI

Total number of letters in given the word = 11

Number of letter P in given word = 2

Let A be a event of choosing a tile with a letter P then

P(A) =Number of tiles with letter P / Total letters in given word

= 2 /11 = 0.18

The probability of choosing a tile with the letter P from the word 'Mississippi' is 1/11.

The probability of choosing a tile with the letter P can be calculated by determining the ratio of the number of P tiles to the total number of tiles.

In the word 'Mississippi', there is only 1 letter P. The total number of letters in 'Mississippi' is 11. Therefore, the probability of choosing a tile with the letter P is 1/11.

So, the theoretical probability of choosing a tile with the letter P is 1/11.

1.  The inequality 8d ≤ 3000 when Andrew is renting a camera that cost d dollars per day for 8 days. He can only spend $3,000.

2. There are 5760 frames in that scene.

3. Andrew's footage ratio is 6, meaning he shot 6 times more film than what was eventually used in his 1 hour and 30-minute movie.

1. Let's create an inequality to represent Andrew's budget for renting the camera. The cost of renting the camera per day is represented by "d" dollars. He wants to rent it for 8 days, and his budget is $3,000.

The total cost of renting the camera for 8 days is 8d dollars. Andrew's budget is $3,000.

So, the inequality would be:

8d ≤ 3000

This inequality ensures that the total cost of renting the camera (8d) does not exceed his budget of $3,000.

2. To find the number of frames in a scene, we need to multiply the frame rate (frames per second) by the duration of the scene (in seconds).

Given:

Frame rate = 24 frames per second

Duration of the scene = 4 minutes

First, convert the duration to seconds since the frame rate is given in frames per second:

4 minutes * 60 seconds per minute = 240 seconds

Now, multiply the frame rate by the duration:

Number of frames = 24 frames/second * 240 seconds = 5760 frames

So, there are 5760 frames in that scene.

3. To find the footage ratio, we need to compare the amount of film shot to the amount of film used.

Film shot = 9 hours

Film used = 1 hour and 30 minutes

First, convert the film used to hours:

1 hour and 30 minutes = 1.5 hours

Now, divide the film shot by the film used:

Footage ratio = Film shot / Film used

Footage ratio = 9 hours / 1.5 hours

Footage ratio = 6

So, Andrew's footage ratio is 6, meaning he shot 6 times more film than what was eventually used in his 1 hour and 30-minute movie.

Answer:

The correct answer is:

A line with 4 tick marks labeled Cat, Dog, Rabbit, and Guinea Pig. Cat has 3 crosses, Dog has 2 crosses, Rabbit has 1 cross, and Guinea Pig has 2 crosses. The line is labeled Number of Pets, and title of graph is Pet Owners.

Step-by-step explanation:

The survey is given as:

Pet                Frequency  

Cats                 3

Dogs              2

Rabbits            1

Guinea Pigs 2

When we will draw a line plot where the horizontal axis denote the pet and the cross above the pet represent the number of pets.

Hence, as the frequency of cat is three so there will be three cross above cat.

Similarly as the frequency of dogs is two so there will be two cross above dogs.

the frequency of rabbits is one so there will be one cross above rabbit.

the frequency of Guinea Pigs is two so there will be two cross above Guinea Pigs.

In case of inequalities we have following two rules.

Rule 1:

If we have just greater than > or less than < sign , then we would use open cirlce.

An open dot means the function has no definition at the specific point

Greater Than, >, and Less Than, <, mean the solution does NOT contain the number

Rule 2:

For inequalities. Greater Than or Equal TO, >, and Less Than or Equal TO, <, mean the solution does contain the number.

So in that case we will use closed circle.

Hope that helps.

Answer:

A.-12x^2-5x-102

Step-by-step explanation:

We are given a polynomial of degree 2 where terms are not grouped and simplified.

We have

-21x^2+22x^2-13x^2-10x+5x-102

To get this in proper form we have to group the like terms first

x^2 term = -21x^2+22x^2-13x^2 = x^2 (-21+22-13)

= x^2(-34+22) = -12x^2

x terms are -10x+5x = x(-10+5) = -5x

Constant term is only one = -102

Hence the polynomial in simplified form is

The greatest number of tables needed to serve dinner to 55 guests, with each table having a different number of guests, is 10 tables.

To find the greatest number of tables needed to serve dinner to 55 guests so that each table has a different number of guests, we need to distribute the guests among the tables in a way that maximizes the number of tables. We can start by placing one guest at each table, then add one more guest to each subsequent table until there are no more guests remaining. This will result in the maximum number of tables, with each table having a different number of guests.

Let's see how this works:

After distributing the guests this way, we have used 10 tables, with each table having a different number of guests. Therefore, the greatest number of tables we could use to serve dinner to 55 guests, with each table having a different number of guests, is 10 tables.

Sum = (101) * 100 / 2       Divide by 2

Sum = 101* 50                  Multiply

Sum = 5050                     Answer

The sum of the numbers from 1 to 100 is 5050

The sum of the numbers from 1 to 100 can be calculated using the formula for the sum of an arithmetic series. An arithmetic series is a sequence of numbers where the difference between two consecutive terms is constant. In this case, the difference between successive numbers is 1.

The formula for an arithmetic series's sum (S) is S = n/2 (a + l), where n is the number of terms, a is the first term, and l is the last term.

Here, n = 100 (because we're adding the numbers from 1 to 100), a = 1 (the first number) and l = 100 (the last number). Substituting these values into the formula gives us S = 100/2 * (1 + 100) = 50 * 101 = 5050.

So the sum of the numbers from 1 to 100 is 5050.

Technically you should use "substitution" in place of "transitive property of equality", though they are very closely related ideas. If I were your teacher, then I would accept that answer as valid nonetheless.

-------------------

Substitution says that if a = b and c = b, then a = c. We replace the 'b' in a = b with 'c'. Think of your substitute teacher who replaces your current teacher for a temporary basis. This is how to remember the term "substitution.

On the other hand, the transitive property of equality says that if a = b and b = c, then a = c. The equations chain together and can simplify into one single equation.

Answer:  The required missing number is 10.

Step-by-step explanation:  We are given to find the missing number in the following proportion :

[tex]?:14=15:21.[/tex]

Let the missing number be represented by x.

Then, according to the given information, we have

[tex]x:14=15:21\\\\\Rightarrow \dfrac{x}{14}=\dfrac{15}{21}\\\\\\\Rightarrow \dfrac{x}{14}=\dfrac{5}{7}\\\\\\\Rightarrow x=\dfrac{5}{7}\times14\\\\\Rightarrow x=10.[/tex]

Thus, the required missing number is 10.

To find the new price of an item that has been reduced by a certain percentage, multiply the original price by the percentage (converted to decimal form) to find the discount. Subtract this discount from the original price to get the new price. Therefore, the new price of the item originally priced at $39 and reduced by 85% is $5.85.

This is a basic percentage problem in mathematics. The phrase 'reduced by 85%' implies that we are subtracting 85% of the original price from the original price itself. To find the discount, we multiply the original price by the reduction rate (in decimal form). Then, to get the final price, we subtract the discount from the original price. So, if the original price is $39 and the item has been reduced by 85%, then the discount would be $39. The calculation would look like this:

So, the new price of the item is $5.85.
