If 48 is added to one-third of a number, the triple of the number is the result. What is the number?

Answers

Answer 1

Answer:
Until we know what it is, let's call the number ' M ', for 'Mystery number'.

      The number . . . . M
   The triple of the number . . . 3M
   One third of the number . . . . M/3
48 added to one third of the number. . . . M/3 + 48 .

You said that 48 added to one third of the number makes triple the number,
so I can write
    M/3 + 48 = 3M
and the rest is easy.

Multiply each side by 3 : M + 144 = 9M

Subtract M from each side: 144 = 8M

Divide each side by 8 : 18 = M

Check:

   Is M/3 + 48 equal to 3M ?

   (18/3) + 48 ? = ? 3(18)

   6    + 48 ? = ? 54

54 = 54

   yay !

The graph shows the results of a survey that asked 4300 students ages 7 to 18 what they thought would be the most important benefit of air travel in the future. There are about 40 million students in the United States. If the margin of error is ±3%, what is the range of the number of students ages 7 to 18 who would likely say that "finding new resources for Earth" is the most important benefit of future flight?

Answers

Answer:

What class you be taking

Step-by-step explanation:

To calculate the range of the number of students ages 7 to 18 who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we need to consider the margin of error.

The margin of error (MOE) is ±3%, which means the actual percentage of students who think this way could be 3% higher or 3% lower than the survey result.

First, let's find out the percentage of students who chose "finding new resources for Earth" as the most important benefit of future flight based on the survey:

Percentage from the survey = $ \frac{4300}{40000000} \times 100\% = 0.01075\% $

Now, we need to calculate the upper and lower bounds considering the margin of error:

Upper bound = $ 0.01075\% + 3\% = 0.04075\% $

Lower bound = $ 0.01075\% - 3\% = -0.01925\% $

The lower bound cannot be negative, so we consider it as 0%.

To find the number of students in the United States who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we use the upper bound percentage:

$ 0.04075\% \times 40000000 = 16300 $

So, the range is approximately 16,300 students to 4,300 students.

hello I am trying to figure out how much rent I would have to pay if I abated the rent 30%. My rent is $610.

Answers

If you were to get 30% backed off, lucky you !
You would then pay only the remaining 70%.

70% means 0.70

0.70 x $610 = $427

Which statement is true about a line and a point? A point and a line have length as a dimension to measure. A point is a location and a line has many points located on it. A line and a point cannot lie on the same plane. A line and a point cannot be collinear. 2. Trisha drew a pair of line segments starting from a vertex. Which of these statements best compares the pair of line segments with the vertex? The line segments and the vertex have length as a dimension of measurement and there are three collinear points on each. Line segments and the vertex have two endpoints each and the distance between the end points is their dimension. Line segments have two endpoints and a vertex is a common endpoint where two line segments meet. The line segments and the vertex have their lines extending in one direction only and the lengths of both are infinite.
