The first thing to do is identify the unnecessary information (that they met 2 years ago).  

From there, let's go back three years ago.  We'll call Daniel's age x, and Ben's age will be 3x.  Ben's age is also equal to x + 20.

3x = x+ 20

2x = 20

x = 10

Daniel was 10 three years ago, and Ben was 30.  Now, Ben is 33.

Is positive. In fact, the square of any (real) number other than 0 is always positive.

Answer:

The square of the positive number

Step-by-step explanation:

-2^2 = 4             2^2 = 4

-3^2 = 9             3^2 = 9

Why is this? Because a negative multiplied by a negative is a positive. And when you square a number you are multiplying the number by itself. So two negatives always equal a positive.

Final answer:

The total amount of paper boxes recycled by Tiffany's class over two months is 9 9/10 boxes, after adding 3 1/2 boxes and 6 2/5 boxes using common denominators.

Explanation:

The student's question involves adding together two fractions to find the total amount of recycled paper boxes. Tiffany's class recycled 3 1/2 boxes one month and an additional 6 2/5 boxes the following month. To find the total, we need to add these two fractions.

First, let's convert these mixed numbers into improper fractions:
3 1/2 = 7/2 (since 3  imes 2 + 1 = 7)
6 2/5 = 32/5 (because 6  imes 5 + 2 = 32)

Next, we find a common denominator (which is 10 here) and add the two fractions:
7/2 = 35/10
32/5 = 64/10
Now, we add 35/10 + 64/10 = 99/10.

Finally, we convert the improper fraction back to a mixed number: 99/10 equals 9 whole boxes and 9/10 of a box.

So, Tiffany's class recycled a total of 9 9/10 boxes over the two months.

The surface area of the cylinder with a height of 5 inches and a radius of 3 inches is calculated using the formula A = 2πrh + 2πr² and comes out to approximately 150.796 in² when rounded to the nearest thousandth.

To calculate the surface area of a cylinder, we use the formula A = 2πrh + 2πr², where 'r' is the radius and 'h' is the height of the cylinder. Given the height 'h' is 5 inches and the radius 'r' is 3 inches, we substitute these values into the formula.

Calculating the lateral surface area (the area of the side):
A_lateral = 2πrh = 2π(3 in)(5 in) = 30π in².

Calculating the area of the two bases:
A_bases = 2πr² = 2π(3 in)² = 18π in².

Now, add the lateral area and the area of the bases to find the total surface area:
A_total = A_lateral + A_bases = 30π in² + 18π in² = 48π in².

Using π ≈ 3.14159, the total surface area is: A_total ≈ 48(3.14159) = 150.796 in². Rounded to the nearest thousandth, the surface area of the cylinder is 150.796 in².

Answer:

a)what was concluded is spurious

b) what was concluded could betrue

Step-by-step explanation:

a) Considering the number in Michigan, there is higher number of crimes but considering the population in Minnesota, the population is much less than Michigan, considering the crime the crimes per capital with the population size, Therefore Minnesota could have more crimes than Michigan's so, The conclusion is not true.

b)There is reduction of crimes from 1991 to 2001, so it can be assumed that the population has increased over the times, therefore, the per capita number of crimes decreased.

To assess the crime comparison between Minnesota and Michigan, factors like population and crime rates per 100,000 inhabitants should be taken into account instead of raw totals, considering the FBI's data, including the Uniform Crime Reports and the incoming National Incident-Based Reporting System for enhanced data quality.

When comparing crime rates between states like Minnesota and Michigan, simply looking at the raw numbers does not provide a sufficient analysis. The investigator's conclusion that Minnesotans are more law-abiding based on the comparison of total crimes between Minnesota and Michigan in 2001 ignores important factors that influence crime rates such as population size, demographic variations, economic conditions, educational levels, and urbanization rates. For a more accurate assessment, rates per 100,000 citizens should be calculated because they provide a comparison that accounts for population differences.

According to the Federal Bureau of Investigation (FBI), which publishes Uniform Crime Reports (UCR), there may be inconsistencies in data quality due to differences in reportage by law enforcement agencies. However, the UCR is one of the most comprehensive sources for crime data and is moving towards the National Incident-Based Reporting System (NIBRS) which will provide more detailed data, hopefully leading to better-informed discussions and effective crime prevention strategies.

To correctly interpret crime data, it is critical to consider the context, such as the presence of large cities like Detroit in Michigan, which can have higher crime rates. Nonetheless, crime patterns, such as higher auto theft rates in California and Washington as compared to New York and Wisconsin or varying homicide rates across states, suggest that regional differences can be significant. As the FBI indicates, crime types and their associated factors, like firearm access, can impact crime rates and resultant punitive measures.

Answer:

5/11

Step-by-step explanation:

The simplified fraction that represents 0.45 with a bar over the 45 is 45/99 => 5/11.

correct option: 5 Over 11

Here, we have,

we have to break down the decimal 0.45.

The digit 4 is in the tenths place, and the digit 5 is in the hundredths place.

To convert this decimal into a fraction, we can write it as:

0.45 = 4/10 + 5/100

Simplifying the fractions:

0.45 = 2/5 + 1/20

Now, to find the fraction equivalent of the repeating decimal 0.45, we need to express it as an infinite geometric series:

0.45 = (2/5) * (1 + 1/5 + 1/25 + ...)

The sum of an infinite geometric series can be calculated using the formula:

Sum = a / (1 - r)

where a is the first term and r is the common ratio.

In this case, a = 1/5 and r = 1/5.

Sum = (1/5) / (1 - 1/5)

Sum = (1/5) / (4/5)

Sum = (1/5) * (5/4)

Sum = 1/4

Therefore, the fraction equivalent of the repeating decimal 0.45 is 1/4.

However, among the given options, the fraction 45/99 is the closest approximation to 1/4.

This is because 45/99 can be simplified to 5/11, which is the closest fraction to 1/4.

Answer: The average speed of the rollercoaster is 30 meters per second.

Step-by-step explanation:

Hi, since:

Speed rate = distance /time

To answer this question we simply have to divide the length (distance) of the rollercoaster (3,000 meters) by the time spent on traveling it (100 seconds)

Mathematically speaking;

3000 meters / 100 seconds = 30 meters per second

The average speed of the rollercoaster is 30 meters per second.

Answer:

The average speed of the roller coaster is 30 m/s.

Step-by-step explanation:

The average speed of the roller coaster can be computed by the formula:

Average Speed = Total distance traveled/Total time taken

The roller coaster travels a distance of 3000 meters and takes a time of 100 seconds. So,

Average Speed = 3000 meters / 100 seconds

Average Speed = 30 meters/second

Answer:

Step-by-step explanation:

In this question we are trying to calculate the cost of exact amount of fabric used given the cost per area of the fabric.

To answer this question mathematically, we need to know the area of the bulletin board. To do this , we employ a mathematical approach. We know that the bulletin board is circular in shape from the question and thus we calculate the area of this shape.

Mathematically, the area of the circular bulletin board is pi * r^2 where r refers to the radius. From the question, we can identify that this radius is 2.5 feet. let’s insert this into the equation we have.

mathematically A = 2.5^2 * pi = 19.63 sq. feet

The cost of the fabric per square feet is 1.48.

now the cost for this area that we have will be 1.48 * 19.63 = 29.0524

This is nearest to 29

Answer: Adult 84

Children 34

Junior 2

Step-by-step explanation:

Adults tickets = $5

Children tickets = $.10

Junior tickets = $2

Total ticket sold = 120 at $119

Total tickets price

= Adults + junior + children

= 5 + 2 + 0.10 = 7.1

No of tickets sold for adults

= 5 / 7.1 × 119

= 84

No of tickets sold for children

= 2/7.1 × 119

= 34

No of tickets sold for junior

= 0.10/7.1 × 119

= 2

Total ticket sold

= 84 + 34 + 2

= 120

Final answer:

During the sale, 22 adult tickets, 67 junior tickets, and 31 children's tickets were sold.

Explanation:

Let's assume that the number of adult tickets sold is x, the number of junior tickets sold is y, and the number of children's tickets sold is z.

According to the information given, the cost of an adult ticket is $5, the cost of a junior ticket is $2, and the cost of a children's ticket is $0.10 (10 cents).

The total number of tickets sold is 120, so we can write the equation:

x + y + z = 120

Additionally, the total amount collected from the ticket sales is $119, so we can write the equation:

5x + 2y + 0.10z = 119

We now have a system of equations that we can solve to find the values of x, y, and z.

By using substitution or elimination methods, we can find that x = 22, y = 67, and z = 31.

Therefore, during the sale, 22 adult tickets, 67 junior tickets, and 31 children's tickets were sold.

Answer:

6 bottles , [tex]\frac{1}{2} \ bottles[/tex]

Step-by-step explanation:

Given:

Every year Sid uses 2 ¾ bottles of washing up liquid.

His friend uses 3 ¼ bottles.

Question asked:

How much do they use altogether?

How much more washing up liquid does his friend use when compared to him?

Solution:

Sid uses bottles of washing up liquid = [tex]2\frac{3}{4}[/tex]

His friend uses bottles of washing up liquid = [tex]3\frac{1}{4}[/tex]

They use bottles of washing up liquid   [tex]=2\frac{3}{4}+3\frac{1}{4}[/tex]

                                                                  [tex]=\frac{4\times2+3}{4} +\frac{4\times3+1}{4} \\ \\ =\frac{11}{4} +\frac{13}{4} \\ \\ =\frac{11+13}{4} \\ \\ =\frac{24}{4} \\ \\ =6\ bottles[/tex]

Thus, they use 6 bottles of washing up liquid together.

Now, to calculate that his friend uses how much more washing up liquid than Sid, we will subtract Sid uses number of bottles from his friend uses number of bottles:-

[tex]=\frac{13}{4} -\frac{11}{4} \\ \\ =\frac{13-11}{4} \\ \\ =\frac{2}{4} \\ \\ =\frac{1}{2} \ bottles\ (half\ bottles)[/tex]

Thus, his friend uses half bottles more than Sid.

Answer:

64 inches

Step-by-step explanation:

We know the following:

- A chessboard is made of 64 white and black squares.

- The 64 squares are arranged in 8 rows and 8 columns.

- Each square is 2 inches thick.

From the first point, we see that a chessboard is a square. This means its length and width are equal.

This is also why the number of rows is equal to the number of columns.

It has been established that there are 8 rows (and 8 columns). Each row is made up of 8 squares.

Therefore, the length of 8 squares (a row) is:

L = 8 * 2 = 16 inches.

Hence, each row (and column) is 16 inches long.

Therefore, Perimeter will be:

P = 4L

P = 4 * 16

P = 64 inches

The perimeter of the chessboard is 64 inches.

Final answer:

The student needs to calculate the perimeter of a chessboard. Multiplying the side of one square (2 inches) by the number of squares (8) gives the length of one side (16 inches). The perimeter is then 4 sides multiplied by 16 inches, resulting in 64 inches.

Explanation:

The student is asking about the perimeter of a chessboard. To find the perimeter, we need to calculate the total length of the chessboard's borders. Since the chessboard has 8 squares along each side and each square has a side length of 2 inches, the length of one side of the chessboard is 8 squares × 2 inches/square = 16 inches. The chessboard is a square with four equal sides, so the perimeter (P) is 4 times the length of one side.

P = 4 × 16 inches = 64 inches

Therefore, the perimeter of the chessboard is 64 inches.

Answer:

The number tickets sold was 120 student tickets, 95 children tickets and 285 adult tickets.

Step-by-step explanation:

Given:

A local theater sell all 500 tickets for a total of $8,070.

The price of tickets were $15 for students, $12 for children, and $18 for adults.

The adult tickets sold were three times as many as children’s tickets.

Now, to find the number of student tickets, children tickets and adult tickets  sold.

Let the number of students ticket be [tex]x.[/tex]

Let the number of children ticket be  [tex]y.[/tex]

So, the number of adults ticket be [tex]3y.[/tex]

Now, the total number of tickets sold:

[tex]x+y+3y=500\\\\x+4y=500\\\\x=500-4y\ \ \ ...(1)[/tex]

Now, the total cost of tickets:

[tex]x(15)+y(12)+3y(18)=8070\\\\15x+12y+54y=8070\\\\15x+66y=8070\\\\Substituting\ the\ value\ of\ x\ from\ equation\ (1):\\\\15(500-4y)+66y=8070\\\\7500-60y+66y=8070\\\\7500+6y=8070\\\\Subtracting\ both\ sides\ by\ 7500\ we\ get:\\\\6y=570\\\\Dividing\ both\ sides\ by\ 6\ we\ get:\\\\y=95.[/tex]

Thus, the number of children ticket is 95.

According the adult tickets sold were three times as many as children’s tickets.

Therefore, the number of adult tickets = 95 × 3 = 285.

Now, substituting the value of [tex]x[/tex] in equation (1) to get the number of student tickets:

[tex]x=500-4y\\\\x=500-4(95)\\\\x=500-380\\\\x=120.[/tex]

Hence, the number of student tickets is 120.

Therefore, the number tickets sold was 120 student tickets, 95 children tickets and 285 adult tickets.

The problem can be solved by creating a system of equations representing each type of ticket sales and their respective prices. Three equations are formed from the information provided and are then solved to find the numbers of each type of ticket sold.

This problem can be solved using a system of equations, representing each type of ticket sales and their prices. Let's define the variables. Let's let x represent the number of student tickets, y represent the number of children's tickets, and z represent the number of adult tickets.

We know that the total number of tickets sold is 500, so we can form the equation:
x + y + z = 500.
Moreover, we know that the total amount of money made from the tickets is $8070, so we can form the equation:
15x + 12y + 18z = 8070.
Lastly, we know that the theater sold three times as many adult tickets as children's tickets, forming the equation:
z = 3y.

Using these three equations, we can substitute and simplify to find the values of x, y, and z, representing the numbers of student, children, and adult tickets sold respectively.

Step-by-step explanation:

The ending balance after 2 years will be equal to $42008.

The amount of interest calculated on the principal amount over a whole year of the loan amount is called simple interest.

In finance and economics, interest is the payment of an amount over repayment of the original sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor. It differs from a fee that the borrower may pay to the lender or a third party.

Given that the amount is $35600 at 9% interest for 2 years. The total balance after 2 years will be,

SI = ( P x R x T ) /100

SI = ( 35600 x 9 x 2 ) / 100

SI = 6408

Ending amount = 6408 + 35600

Ending amount = $42008

Therefore, the ending balance after 2 years will be equal to $42008.

Answer:

A function is a relation where there is only one output for every input. In other words, for every value of x, there is only one value for y. Function Rule. A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3.

Step-by-step explanation:

The concept of a function relies on the idea of a functional dependency, where the output is entirely determined by the input.

A rule is considered a function when it satisfies the fundamental condition of assigning a unique output value to each input value. In other words, for every input, there should be exactly one corresponding output.

A key aspect of a function is that it avoids ambiguity and ensures a consistent mapping between inputs and outputs. Each input value must have a specific and unambiguous output value associated with it. This property distinguishes a function from a general relation, where multiple inputs may have the same output.

Additionally, a function must be well-defined, meaning that it produces a predictable and consistent output for any given input within its domain. The rule should be defined for all valid inputs, without any gaps or exceptions.
