students at a cooking school made a super sized rectangular pizza for a class party Lupita cut the pizza into 3 equal pieces then she cut each piece into three equal parts two more times the pita needs 27 pieces of pizza does she have enough pieces yet explain how you know
Final answer:
After dividing the pizza into 3 equal parts twice, Lupita has the exact number of pieces needed for the party, which is 27.
Explanation:
The student's question is about dividing a rectangular pizza into equal parts. Lupita cut the pizza into 3 equal pieces, then each piece into 3 equal parts two more times. To determine if Lupita has enough pieces for 27 people, we can use multiplication to find how many total pieces she has created. The math goes as follows:
First division: 1 pizza is cut into 3 pieces.
Second division: Each of the 3 pieces is cut into 3 pieces, resulting in 3 x 3 = 9 pieces.
Third division: Each of the 9 pieces is cut into 3 pieces, resulting in 9 x 3 = 27 pieces.
After the final division, there are 27 pieces of pizza. Therefore, Lupita has enough pieces for the party as the required number of pieces is also 27.

renee is making a scale diagram of her mp3 player. The length of her scale drawing is 8 inches, and the width is 14 inches. The actual length of the mp3 player is 4 centimeters, and the width is 7 centimeters.
To create a scale diagram, determine the ratio between the length and width of the scale drawing and the actual object.
Explanation:To create a scale diagram, we need to determine the ratio between the length and width of the scale drawing and the actual object.
In this case, the length of the scale drawing is 8 inches and the actual length of the mp3 player is 4 centimeters.
So the length ratio is 8 inches / 4 centimeters = 2 inches / centimeter.
Similarly, the width ratio can be calculated as 14 inches / 7 centimeters = 2 inches / centimeter.

In Renee's scale drawing of the mp3 player, every 1 cm of the actual mp3 player is represented by 5 cm in the scale drawing. This is calculated by comparing the actual length to the length on the drawing, converting the units to centimeters first. The scale should be consistent for both length and width.
Explanation:The question describes a situation where Renee is making a scale diagram of her mp3 player. In this case, there is a comparison between the actual size of the mp3 player and it's representation on the scale drawing. Let's use the lengths as a basis for the scale.
The length of the actual mp3 player is 4 cm and the length on the scale is 8 inches. But, to make our comparison valid, we need to make sure that both measurements are in the same unit. Now, since 1 inch is approximately 2.54 cm, our 8 inches become 8 × 2.54 = 20.32 cm.
This means Renee's scale is roughly 5 to 1 (since 20.32 divided by 4 is about 5). Therefore, every 1 cm of the actual mp3 player is represented by 5 cm in the scale drawing.
We can follow the same process for the width and verify that the scale is consistent, which it should be, but in this case, it's not necessary because we've been given that the lengths and the widths have exactly the same proportions in both the drawing and the real object.

Jennifer is on a hiking trip. She begins her hike at an altitude of 4,000 feet, and she is descending with an average speed of 40 feet per minute.
Graph the function that represents this situation.
Answer:
See attachment
Step-by-step explanation:
Given : Jennifer is on a hiking trip. She begins her hike at an altitude of 4,000 feet, and she is descending with an average speed of 40 feet per minute.
We have to Graph the function that represents the given situation.
Let the y - axis represents the height of Jennifer (in feet) and x axis represents the time (in minutes)
Since initially, Jennifer is at 4000 feet.
and is descending with an average speed of 40 feet per minute.
So when she begins to descend she is at 4000 feet that is y- intercept is 4000.
Then, the equation of graph is given by
y = -40x + 4000
As she is descending at the rate of 40 feet per minute so -40x
Thus, The graph for the given equation can be drawn as shown below.
also, when x = 100
then y = -40(100) - 4000 = 0
Plot points (0, 4000) , (100,0) to obtain the graph.

The correct answer is (A) -2y - 2 for x in 3x - 2y = 10.
x + 2 = -2y
3x - 2y = 10
In order to find the second variable, we must take either x or y out of one of the equations. We can specifically exclude x by substituting the following in the expression:
From the first equation into the second, x = -2y - 2. With this change, x will no longer be present in the second equation, allowing us to determine the value of y. As a result, we must replace the phrase with:
For x in the equation, -2y - 2:
3x - 2y = 10
To acquire:
3(-2y - 2) - 2y = 10
To put it simply: -6y - 6y - 2y = 10
combining comparable phrases
-8y = 16
y = -2 after dividing both sides by -8.
Once y has been determined, we can add this result back into one of the original equations.
Therefore, the correct answer is (A) -2y - 2 for x in 3x - 2y = 10.

The taxi fare in Gotham City is $2.40 for the first 1/2 mile and additional mileage charged at the rate $0.20 for each additional 0.1 mile. You plan to give the driver a $2 tip. How many miles can you ride for $10? (An explanation would be helpful!)
Answer:
I can ride 3.3 miles in $10.
Step-by-step explanation:
Let i can ride x miles in $10.
So for first 0.5 miles I have paid = $2.4
The for remaining ride of (x - 0.5) payment done = $[tex]\frac{0.20}{0.1}\times (x-0.5)=2(x - 0.5)[/tex]
I gave the tip = $2
Total payment I have done for the ride = $10
So equation will be
2.4 + 2(x - 0.5) + 2 = 10
4.4 + 2x - 1 = 10
3.4 + 2x = 10
2x = 10 - 3.4
2x = 6.6
x = [tex]\frac{6.6}{2}=3.3[/tex]
Therefore, i can ride 3.3 miles in $10.
Josh wanted to buy a bike but didn't have enough money. Sam Slick said, "I can fix that. Each time you jump that fence, i'll triple your money. There's one small thing though. Each time I pay, you must give me $54 back for the priviledge of jumping." Josh agreed, jumped the fence, received his payment from sam slick, and paid sam $54. Repeating the routine 1 more time, josh was distressed to find that after sam had made his payment to josh, josh had only $54 with which to pay sam and so had nothing left. Sam, of course, went merrily on his way, leaving josh wishing that he had known a little more about mathematics.
We can see here that according to the agreement, each time Josh jumped the fence, his money would be tripled. Thus, Josh had to pay Sam $54 back for the privilege of jumping.
Josh jumped the fence for the first time. Sam Slick paid Josh the agreed-upon amount, which was triple the initial money Josh had. Then Josh paid Sam $54 back as per the agreement.
We see that Josh jumped the fence for the second time. Sam Slick paid Josh the agreed-upon amount, which was triple the money Josh had after paying Sam $54. After Josh received the payment, he had only $54 left, which was exactly the amount he needed to pay Sam.

You select a marble without looking and then put it back. If you do this 6 times, what is the best prediction possible for the number of times you will pick a purple or a blue marble?
Without further information, we can say that the prediction of drawing a blue or purple marble in six attempts depends on the total number of marbles and the number of blue and purple marbles.
If half the marbles are blue or purple, there is a predicted average of three such draws in six attempts.
To predict how many times you could pick a purple or blue marble, we would need to first know the total number of marbles and the number of blue and purple marbles. This information isn't provided in the question. However, we can discuss this concept further. When you select a marble and put it back, the probabilities remain the same for each draw because the total number of marbles in the bag and the number of desirable marbles (blue or purple in this case) do not change.
For example, if a bag contains four blue marbles and three white marbles, and you draw one marble six times with replacement (meaning each time after drawing, you put the marble back into the bag), the probability of drawing a blue marble each time is 4/7, because there are four blue marbles and seven total marbles.
Therefore, the best prediction of the number of times you will draw a blue or purple marble in six tries depends on these individual probabilities. If we assume half the marbles are blue or purple, then on average, we would expect to draw a blue or purple marble about three times.

The best prediction possible for the number of times you will pick a purple or a blue marble after 6 draws is 3.43 times.
Explanation:To predict the number of times you will pick a purple or a blue marble, you need to determine the probability of picking a purple or a blue marble for each individual draw and then multiply that probability by the number of draws. In this case, the bag contains 4 blue marbles out of a total of 7 marbles.
Therefore, the probability of picking a blue marble on each draw is 4/7.
Since you are drawing 6 times, you can predict that you will pick a purple or a blue marble approximately (4/7) x 6 = 24/7 = 3.43 times.
