A single bus fare costs $2.35. A monthly pass costs $45.75. Celine estimates that she will ride the bus 25 times this month. Kamal estimates that he will ride the bus 18 times. should they both buy monthly passes? Explain.

Answer:

false

Step-by-step explanation:

Since in the question it is mentioned that the wages would be increased by 2% and rent would increase by 5%

So, the increased value of both is

= $450 × 1.02

=  $459

And,  

= $200 × 1.05

= $210

As the wages are increased to $9 and the rent is increased to $10 since the amount is not equivalent to each other so the given statement is false

Answer:

325

Step-by-step explanation:

Writing out the equation always makes it easier to solve:

( 21 / 7 ) + 7 + 7( 7 - 2 ) x 9

First, following the rules of P.E.M.D.A.S.

(parenthesis, exponents, multiplication, division, addition, subtraction.)

You would need to solve for the values within each parenthesis... so

(21 / 7). 21 divided by 7 is equal to 3. And in (7 - 2). 7 minus 2 is equal to 5.

The equation is now:

( 3 ) + 7 + 7( 5 ) x 9

Next you must solve for multiplication, so:

7( 5 ), 7 times 5 is 35. the equation is now:

( 3 ) + 7 + ( 35 ) x 9

Then, 35 x 9 is equal to 315. The equation is now:

( 3 ) + 7 + 315.

If you add everything together, you get the answer of:

325!!!

In this problem, we are looking at a special case of matrix multiplication. We assume that "n" is a power of 2. We have matrix "a," which is an n × n matrix, and matrix "b," which is also an n × n matrix. In matrix "b," every element is a fixed constant "c."

To perform the matrix multiplication, we need to multiply each element in matrix "a" by the corresponding element in matrix "b" and sum up the results.

Since every element in matrix "b" is the same constant "c," the multiplication simplifies to multiplying each element in matrix "a" by "c."

Here are the steps for the multiplication:

1. Iterate through each row and column of matrix "a."
2. Multiply each element in matrix "a" by the constant "c."
3. Sum up the products obtained in step 2 to get the final result.

Answer: Nonresponse, voluntary, and convenience.

Step-by-step explanation:

For the first question, it should be noted that everyone cannot respond as only the people who have strong opinions will respond. Therefore, it's a nonresponse error.

For the second question, the people will have to volunteer. Therefore, it's a voluntary bias while the third one is a convenience sample as it's an easily available sample.

The relationship that is normally expressed as the quotient of one quantity divided by another is called a ratio

The relationship that is normally expressed as the quotient of one quantity divided by another is called a ratio. A ratio is a comparison of two numbers or measurements, and it can be written in different ways.

For example, if we have two quantities A and B, the ratio of A to B can be written as

A/B

A:B

"A is to B"

The ratio of A to B tells us how many times A is contained within B, or how many units of A we would need to have to match the amount of B.

Ratios are useful in many fields, such as finance, engineering, and science, where they are used to compare and analyze different quantities and their relationships.

The value is 63 so that the percentage of only children that have no pets is 37.5%. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

The four basic operations, often referred to as "arithmetic operations" are thought to be able to account for all real numbers. Divide, multiply, add, and subtract are the four mathematical operations that result in the quotient, product, sum, and difference.

We are given a table showing whether people have any brothers or sisters or are an only child, and whether they have pets.

Let the number of only children that have no pets be 'x'.

The total number of only children = 105 + x

We are given that the percentage of only children that have no pets is 37.5%.

So,

x/ (105 + x) * 100 = 37.5%

On solving this, we get

⇒x/ (105 + x) = 0.375

⇒x = 0.375(105 + x)

⇒x = 39.375 + 0.375x

⇒0.625x = 39.375

⇒x = 63

Hence, the value that will go in the cell is 63.

The missing figure is attached below

Let \(\(a\)\) and \(\(b\)\) be integers such that \(\(ab = 4\)\). We want to prove that \(\((a - b)^3 - 9(a - b) = 0\).\)

Starting with the left side of the equation, we have:

\(\((a - b)^3 - 9(a - b)\)\)

Using the identity \(\((x - y)^3 = x^3 - 3x^2y + 3xy^2 - y^3\)\), we can expand the cube of the binomial \((a - b)\):

\(\(a^3 - 3a^2b + 3ab^2 - b^3 - 9(a - b)\)\)

Rearranging the terms, we have:

\(\(a^3 - b^3 - 3a^2b + 3ab^2 - 9a + 9b\)\)

Since \(\(ab = 4\)\), we can substitute \(\(4\)\) for \(\(ab\)\) in the equation:

\(\(a^3 - b^3 - 3a^2(4) + 3a(4^2) - 9a + 9b\)\)

Simplifying further, we get:

\(\(a^3 - b^3 - 12a^2 + 48a - 9a + 9b\)\)

Now, notice that \(\(a^3 - b^3\)\) can be factored as \(\((a - b)(a^2 + ab + b^2)\):\)

\(\((a - b)(a^2 + ab + b^2) - 12a^2 + 48a - 9a + 9b\)\)

Since \(\(ab = 4\)\), we can substitute \(\(4\)\) for \(\(ab\)\) in the equation:

\(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 48a - 9a + 9b\)\)

Simplifying further, we get:

\(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 39a + 9b\)\)

Now, we can observe that \(\(a^2 + 4 + b^2\)\) is always greater than or equal to \(\(0\)\) since it involves the sum of squares, which is non-negative.

Therefore, \(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 39a + 9b\)\) will be equal to \(\(0\)\) if and only if \(\(a - b = 0\)\) since the expression \(\((a - b)(a^2 + 4 + b^2)\)\) will be equal to \(\(0\)\) only when \(\(a - b = 0\).\)

Hence, we have proved that if \(\(ab = 4\)\), then \(\((a - b)^3 - 9(a - b) = 0\).\)

Josue used 150 square centimeters of wrapping paper to cover the cube-shaped gift box

To determine the amount of wrapping paper used by Josue for the cube-shaped gift box, we need to calculate the surface area of the cube.

The net of the gift box consists of six squares, each representing a face of the cube. The dimensions provided in the figure show that each side of the squares is 5 cm.

Since a cube has six faces, we need to calculate the total surface area by multiplying the area of one square face by six.

The formula to find the area of a square is side length squared, so we can calculate the area of one square face as 5 cm * 5 cm = 25 cm².

Now, to find the total surface area, we multiply the area of one face by six: 25 cm² * 6 = 150 cm².

Therefore, Josue used 150 square centimeters of wrapping paper to cover the cube-shaped gift box.

It's worth noting that this calculation assumes that there is no overlap or excess wrapping paper used while wrapping the gift box. Additionally, we have assumed that the dimensions provided are accurate and refer to the side length of the squares in the net.

Overall, the amount of wrapping paper used can vary based on the wrapping technique employed and any additional decorations or folds added to the gift box.

Answer:

If the trader bought the TV set for Birr 2000 and sold it at a profit of 10%, the selling price can be calculated as follows:

Profit = 10% of the cost price = 10/100 * 2000 = Birr 200

Selling price = Cost price + Profit = 2000 + 200 = Birr 2200

Now, if the profit was a loss, we can use the same rate of 10% to calculate the selling price. In this case, the profit will be negative, indicating a loss.

Loss = 10% of the cost price = 10/100 * 2000 = Birr 200

Selling price = Cost price - Loss = 2000 - 200 = Birr 1800

Therefore, if the trader sold the TV set at a loss of 10%, the selling price would be Birr 1800.
