Answer:

56 is 40% of the original number

Step-by-step explanation:

Let [tex]n[/tex] represent the original number

We are given that  

30% of number is 42

70% of the same number is 98

Lets convert the precents to decimals

30% as a decimal is [tex]0.3[/tex]

70% as a decimal is [tex]0.7[/tex]

We can create an equation for each scenario

[tex]0.3n=42\\0.7n=98[/tex]

We can choose either one to evaluate [tex]n[/tex].

[tex]0.3n=42[/tex]

Lets solve for [tex]n[/tex].

Divide both sides by [tex]0.3[/tex].

[tex]n=\frac{42}{0.3}[/tex]

Evaluate [tex]\frac{42}{0.3}[/tex].

[tex]n=140[/tex]

Now that we know what the original number is we can calculate what 40% of the number is.

40% as a decimal is [tex]0.4[/tex].

[tex]140*0.4=56[/tex]

In physics lab, when you measure three quantities of x, y, and z, you can use these mathematical combinations to find meaningful relationships between these quantities:  

In this case, x=2.5 kg, y=0.8 m, and z=4.9 kg/m.

Based on the given quantities' scale, we know that x, y, and z have a relationship where:

z = x/y

Then, the mathematical combinations that might be meaningful are:

- (x/y) - z: This combination gives you the difference between the ratio of x and y, and z. This could be meaningful if you are trying to find the difference between two quantities that have different units.

- (x/z) - y: This combination gives you the difference between the ratio of x and z, and y. This could be meaningful if you are trying to find the difference between two quantities that have different units.

The correct answer to the given question about all of the diagonals drawn from a vertex of an n-gon is option b) n-1

If all of the diagonals are drawn from a vertex of an n-gon, the number of triangles formed is equal to the number of non-diagonal sides of the n-gon. To see why, imagine selecting a vertex of the n-gon and drawing all of the diagonals from that vertex. Each diagonal connects that vertex to a non-adjacent vertex of the n-gon, which splits the n-gon into a series of triangles. The total number of triangles formed is equal to the number of non-diagonal sides of the n-gon, because each non-diagonal side forms one triangle with the selected vertex and one of its adjacent vertices. An n-gon has n sides, so the number of non-diagonal sides is equal to n - 3. This is because each vertex is connected to two adjacent vertices, so there are n - 2 diagonal sides emanating from the selected vertex, and the remaining n - 2 sides are non-diagonal. In addition, there are three sides at the selected vertex that are not counted as non-diagonal sides, so we subtract 3 from n - 2 to get n - 3. Therefore, the answer is (B) n - 1.

The graph of g(x)=f(x)-d crosses the y-axis at (0,c-d).

What does y-intercept mean?

The point on a line where it crosses the y-axis is known as the y-intercept. To put it another way, it is the value of y when x is equal to 0.

It is given that graph  [tex]f(x)=ce^{x}[/tex] crosses the y-axis at (0,c).

Because at x=0,

[tex]f(0)=ce^{0}\\f(0)=c[/tex].

So, if g(x)=f(x)-d

[tex]g(x)=ce^{x}-d[/tex]

when x=0:

Susan bought 6 boxes of chocolate cookies, and 2/5(6) = 2.4 or 2 boxes of butter cookies.

Let's call the number of boxes of chocolate cookies that Susan bought "C". Then, she bought 2/5 as many boxes of butter cookies, which is 2/5C.

Let's call the cost of each box of chocolate cookies "x". Then, the cost of each box of butter cookies is x-2, since each box of butter cookies costs $2 less.

We know that the total cost of the chocolate cookies was $84 more than the total cost of the butter cookies. This can be expressed as:

Cx = 2C/5(x-2) + 84

Simplifying this equation, we get:

3/5Cx = 84 + 2/5C(2)

Multiplying both sides by 5/3, we get:

Cx = 140 + 4C/3

We also know that the total cost of all the cookies was $156, which can be expressed as:

Cx(x) + (2/5C)(x-2) = 156

Substituting Cx from the previous equation, we get:

(140 + 4/3C)(C) + (2/5C)(C-2) = 156

Simplifying and solving for C, we get:

C = 6

So Susan bought 6 boxes of chocolate cookies, and 2/5(6) = 2.4 or 2 boxes of butter cookies.

Thus, the required rest stops are approximately 4.09 miles apart on the new map.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
The total length of the highway in miles can be found by using the scale of the original map. Since 2 inches on the map represent 33 miles in reality, 6 inches on the map represent:

= 6 inches × (33 miles/2 inches) = 99 miles

Since there are 11 equally spaced rest stops along the highway,

= (99 miles)/(11 intervals) = 9 miles per interval

To create the new map with a scale of 1 inch = 30 miles, we need to use a scale factor of (1/2) × (30/33) = 15/33.

Therefore, the distance between each rest stop on the new map can be found by multiplying the distance between rest stops on the old map by the scale factor,

= (9 miles per interval) × (15/33) = 4.09 miles per interval

So, the required rest stops are approximately 4.09 miles apart on the new map.

There are 2002 groups of 5 people that can answer the 5 phone lines.

This is a combination problem, because we want to choose groups of 5 people from a group of 14, and the order in which we choose the people does not matter.

The formula for the number of combinations of n objects taken r at a time is:

C(n,r) = n! / (r! * (n-r)!)

In this case, we want to choose 5 people out of a group of 14, so we can plug those values into the formula:

C(14,5) = 14! / (5! * (14-5)!)

Simplifying the factorial terms:

C(14,5) = (1413121110) / (54321)

C(14,5) = 2002

For a z-score, We  transform a set of raw scores into a set of z-scores because we can compare scores from two different distributions i.e. D.

What exactly is the z-score?

The z-score is a statistical measurement that describes a value's relationship to the mean of a collection of values. The z-score formula is

z = (x - μ)/σ

x = data point

μ = mean

σ = standard deviation

Mean:- The sum of a collection of numbers divided by the total number of numbers in the set is known as the arithmetic mean, sometimes known as the arithmetic average or simply the mean or average. A survey, experiment, or observational research is usually used to create the collection.

Now,

As Z-scores are standardized scores that identify and define each score's exact placement within a distribution. We may conduct meaningful comparisons of z-scores across various samples or groups by converting our data (raw score).

Answer:1024 grid squares

Step-by-step explanation:

Let's call the side length of the original piece of graph paper "x".

Since, side length of the cut out square is then (x-2) because the cut out square has to have an integer number of grid squares, and each side of the square would take up 2 grid squares on the graph paper.

The number of grid squares in the cut out square is then (x-2)^2.

The number of grid squares left on the graph paper is 124, so we have:

x^2 - (x-2)^2 = 124

Expanding the right side:

x^2 - x^2 + 4x - 4 = 124

Simplifying:

4x = 128

therefore:

x = 32

therefore original graph paper contains 32 grids i.e 32^2 = 1024

Answer:

  any of {128, 133, 140, 160, 224, 320, 380, 700, 1024}

  1024 if the original grid was square

Step-by-step explanation:

You want to know how many grid squares are on a piece of graph paper if a square number of grid squares can be cut from it to leave 124 grid squares.

If the graph is square to begin with, a square of x² can be removed from its size (x+a)² to leave 124 squares. That is ...

  (x +a)² -x² = 124

  (a)(2x+a) = 124

The factor pairs of 124 are ...

  124 = 1·124 = 2·62 = 4·31

Of these, only 2 and 62 differ by an even number, so we have a=2 and x=30.

The graph paper could be 32 units square originally, having 1024 grid squares.

There is nothing in the problem statement that requires the original graph paper be square. If it is not necessarily square, there are 13 possible shapes it could be. Those have 9 different possibilities for numbers of grid squares.

The graph paper could have originally had this number of grid squares:

Answer: Dear Editor,

I am writing to bring to your attention the serious issue of rising air and noise pollution in our area. The daily air quality index that appears in the newspaper highlights the extent of the problem, and I believe it is important for the public to be aware of its effects.

Air pollution has been linked to a number of health problems, including respiratory issues, heart disease, and even cancer. The presence of harmful pollutants in the air we breathe is cause for concern and demands immediate attention. Similarly, noise pollution can lead to hearing loss, sleep disturbance, and increased stress levels.

It is imperative that we take action to curb the effects of air and noise pollution. There are several measures that can be taken, both by individuals and by the government. On an individual level, we can reduce our carbon footprint by using public transportation, carpooling, or biking instead of driving alone. We can also plant trees and install air purifiers in our homes.

The government, on the other hand, can take steps to regulate industrial emissions, enforce stricter penalties for violators, and promote the use of clean energy sources. Additionally, they can create green spaces and establish noise-free zones in residential areas.

In conclusion, the rise in air and noise pollution is a pressing issue that affects the health and well-being of everyone in our community. I urge the public to take this matter seriously and support efforts to reduce its impact. Together, we can work towards a cleaner and healthier future.

Sincerely,

[Your Name]
