Option (A) The first theme park had about 5 times as many guests than the second.
Step-by-step explanation:Number of guests in the First Theme Park = 2 * 10^7
= 2 * 10 * 10 * 10 * 10 * 10 * 10 * 10
= 20 * 100 * 100 * 100
= 2000 * 10000
= 20000000
Number of guests in the Second Theme Park = 4 * 10^6
= 4 * 10 * 10 * 10 * 10 * 10 * 10
= 4 * 100 * 100 * 100
= 400 * 10000
= 4000000
Now we can observe that, the number of guests in the First Theme Park is more than the number of guests in the Second Theme Park.
Let’s start dividing to find how many times the First Theme Park has more guests than the Second Theme Park.
Number of guests in the First Theme Park = 20000000
Number of guests in the Second Theme Park = 4000000
Number of times, the First Theme Park has more guests than the Second Theme Park = 20000000/4000000
= 2000000/400000
= 200000/40000
= 20000/4000
= 2000/400
= 200/40
= 20/4
= 5 times

Francisco wants to find the product of 382 trays of apples and the 18 apples that fit in each tray. He decides to find the answer by breaking 18 into equal parts: 9 and 9. He says that if he multiplies 382 by 9 and then multiplies the product by 9 again, he can find the answer.
Will Francisco’s strategy work? Why or why not?
Answer:
Please mark me the brainliest
Step-by-step explanation:
Yes, Francisco's strategy will work.
Breaking 18 into 9 and 9 means that he is using the distributive property of multiplication, which states that a(b+c) = ab + ac. In this case, he is breaking 18 into 9 and 9, so he can rewrite the product of 382 trays and 18 apples as:
382 trays x (9 apples + 9 apples)
Using the distributive property, this can be expanded as:
(382 trays x 9 apples) + (382 trays x 9 apples)
This simplifies to:
3,438 trays x 9 apples
Which gives the correct answer of 30,942 apples. Therefore, Francisco's strategy works because he correctly applied the distributive property of multiplication to break down the problem into simpler parts.

Edgar measures the temperature of a solution at the beginning of an experiment to be 23°F. He monitors the temperature of the solution every minute for 10 minutes. He records the change in temperature from his previous reading. His data show a decrease of 2°F four times, a decrease of 3°F three times, no temperature change two times, and an increase of 6°F once.
(a) Write an expression that represents the average change in temperature each minute.
(b) Edgar repeats the experiment and finds the average change in temperature each minute is greater in the second trial than in the first trial. What is the average change in temperature each minute in the second trial of the experiment? Show your work.
Answer:
To find the average change in temperature each minute in the first trial of the experiment, we need to add up all of the temperature changes Edgar recorded and divide by the number of temperature changes he recorded. We can represent this with the following expression:(2 degrees F x 4) + (3 degrees F x 3) + (0 degrees F x 2) + (6 degrees F x 1) / 10 temperature changes= 8 degrees F + 9 degrees F + 0 degrees F + 6 degrees F / 10 temperature changes= 23 degrees F / 10 temperature changes= 2.3 degrees F/minute This means that the average change in temperature each minute in the first trial of the experiment was 2.3 degrees F.To find the average change in temperature each minute in the second trial of the experiment, we need to determine the average change in temperature each minute in the second trial. This value will be greater than 2.3 degrees F, since the average change in temperature each minute was greater in the second trial than in the first trial. However, we do not have any information about the specific temperature changes Edgar recorded in the second trial, so it is not possible to calculate the average change in temperature each minute in the second trial.

If you were looking to find the mean of a set of numbers, what would be the correct first step?
a)add the smallest and largest numbers together
b)add all the numbers together
c)subtract the smallest number from the largest number
d)find the number at the midpoint of the set
Answer:
Option B is the correct answer.
Step-by-step explanation:
To find the mean of a set of numbers, you would first add up all of the numbers in that set. Then, you would divide this sum by the number of values that were added up. This would result in the mean.
Example:
Set of Numbers: 10, 5, 15
1.) Add the numbers
10+5+15=30
2.) Divide 30 by the number of values that were added together. Three numbers were added, so you would divide 30 by 3.
30/3=10
The mean of this set would be 10.

Carlos needs an average of 90% or greater on his quiz scores to earn an A in science class for the quarter. Each quiz is worth 20 points. The scores of his first four quizzes are shown in the table. There is one more quiz this quarter.
Quiz Score
1 18
2 19
3 17
4 20
What is the minimum score Carlos can earn on the final quiz to earn at least a 90% average?
Answer: Carlos can score a minimum of 16 points
Step-by-step explanation:
each quiz is worth 20 points, so 20*5= 100 points in total (it is multiplied by 5 because he will be taking 5 tests in total), Carlos has earned a total of 74 points. In order for Carlos to receive a 90% average, he would need a 90/100, so 90-74= 16, therefore, Carlos needs a 16/20 in order to earn a 90% for the quarter.
On solving the provided question we can say that by percentage he need to scores 16 point in each
What is percentage?
A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Mrs. Smith bought an 8 pound pumpkin so she could make a pie. The pumpkin cost $6.80 How much did the pumpkin cost per pound?
To find the cost per pound of the pumpkin, we need to divide the total cost of the pumpkin by its weight in pounds.
Cost per pound = Total cost / Weight
Cost per pound = $6.80 / 8 pounds
Cost per pound = $0.85
Therefore, the pumpkin cost $0.85 per pound.

Use the equation of the line of best fit and the value of x found for the year 2030 to estimate the CPI for the year 2030.
Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2
Answer:
Please mark me the brainliest
Step-by-step explanation:
The three equivalent equations are:
1. Negative 5 + x = negative 2
2. 2 + x = 5
3. x + 1 = 4
Explanation:
1. Negative 5 + x = negative 2 can be solved by adding 5 to both sides, which gives x = 3.
2. 2 + x = 5 can be solved by subtracting 2 from both sides, which gives x = 3.
3. x + 1 = 4 can be solved by subtracting 1 from both sides, which gives x = 3.
Therefore, the three equivalent equations are those where x = 3. The other equation, 9 + x = 6, can be solved by subtracting 9 from both sides, which gives x = -3, and is not equivalent to the other three equations. Similarly, x + (negative 4) = 7 can be solved by adding 4 to both sides, which gives x = 11, and is also not equivalent to the other three equations.
Use your equation to determine the initial cost to the company, in dollars.
Initial cost to the company $ __
(The equation is c=5.25t-75.)
Answer: The initial cost to the company is $-75.
Step-by-step explanation:
To determine the initial cost to the company using the equation provided (c = 5.25t - 75), we need to understand what each variable represents:
c: The cost to the company in dollarst: The time (usually measured in hours, days, or weeks)Since the initial cost refers to the cost at the beginning (t = 0), we can plug t = 0 into the equation and solve for c:
c = 5.25(0) - 75
c = 0 - 75
c = -75
In this context, the initial cost to the company is $-75. It might seem unusual for the cost to be negative; however, this could be interpreted as the company having an initial credit or saving of $75 before any time has been spent on the project. Please note that the specific interpretation of this negative value depends on the context of the problem and the real-world situation being modeled by the equation.

The population of the West was about 53 million in 1990. The population of this area increased an average of about 1 million a year during the 1990s. What is the equation?
Answer:
Let P be the population of the West in a certain year, and t be the number of years after 1990.
Since the population increased by about 1 million a year during the 1990s, we can model the population as:
P = 53 + 1t
where 53 represents the population of the West in 1990 and 1 represents the average increase in population per year.
So for example, in 1992 (two years after 1990), the population of the West would be:
P = 53 + 1(2) = 55 million
Similarly, in 1995 (five years after 1990), the population of the West would be:
P = 53 + 1(5) = 58 million
And so on for any year t after 1990.

The answer for
x=3/4
y=3/2
Step-by-step explanation:
let bigger number be x
let the smaller number be y
x+y=3¾
x+y=15/4
x=15/4-y
x+1/2=2/3y
x+1/2=2y/3
15/4-y=2y/3
C.LT.
-y-2y/3= -15/4
-3y-2y/3= -15/4
-5y/3= -15/4
-5y×4=3×-15
-20y= -45
divide both sides by-20
-20y/-20= -45/-20
y=9/4
x+y=15/4
x=15/4-y
x=15/4-9/4
x=6/4
x=3/2
