Answer:

[tex]Actual\ Length : Scale\ Length = 8 : 1[/tex]

Step-by-step explanation:

Given

[tex]Actual\ Length = 12\frac{1}{2}ft[/tex]

[tex]Scale\ Length = 1\frac{9}{16}ft[/tex] --- See attachment

Required

Determine the scale used

The scale of the drawing can be represented using the following ratio

[tex]Scale = Actual\ Length : Scale\ Length[/tex]

Substitute values for actual and scale lengths

[tex]Scale = 12\frac{1}{2}: 1\frac{9}{16}[/tex]

Convert to improper numbers

[tex]Scale = \frac{25}{2}: \frac{25}{16}[/tex]

Convert to division:

[tex]Scale = \frac{25}{2}/\frac{25}{16}[/tex]

[tex]Scale = \frac{25}{2}*\frac{16}{25}[/tex]

[tex]Scale = \frac{1}{2}*\frac{16}{1}[/tex]

[tex]Scale = \frac{16}{2}[/tex]

[tex]Scale = \frac{8}{1}[/tex]

Convert to ratio

[tex]Scale = 8 : 1[/tex]

Hence, the scale of the drawing is:

[tex]Actual\ Length : Scale\ Length = 8 : 1[/tex]

Answer:

18 students

Step-by-step explanation:

Now think of it in this form. 12 students wanna learn french which is 24% and in this problem we have to find 24% of "x" is 12. The answer is obviously 50. Now go to German and you can see that 18% want to learn German. All you have to do is find 50% of 18 to get your answer which is 9. Now follow that same pattern with the Spanish one. If 36% want to learn Spanish, just find 50% of it or half of it and that could be done by doing 36 divided by 2 to get 18 as your answer. Another way to do it is my turning 50% into 0.5 and multiplying it by 36 to get your answer. As a result, your answer is 18 students want to learn Spanish.

Answer:  They received  $14.58

Step-by-step explanation:

Set up a proportional relationship

If  2 cents equal to 3 cans then we will represent how  2,187 will be worth by x.

[tex]\frac{0.02}{3} / \frac{x}{2187}[/tex]      Cross multiply

   3x = 43.74    Divide both sides by 3

x = 14.58

Answer:

D) 13x + 5

Step-by-step explanation:

Combine like terms

Here, 6x and 7x are like terms

5 + 6x + 7x = 5 + 13x

                  =13x + 5

The zeros are x=0,3,-2

There is a multiplicity of 1 for all of them.

Step-by-step explanation:

The required value of a is 3 for the given function.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The function is given as follows:

f(x) = 5x²– 3

Substitute the value of x = x + a in the above function,

f(x + a) = 5(x + a)²– 3

f(x + a) = 5(x² + a² + 2ax) - 3

f(x + a) = 5x² + 5a² + 10ax - 3

f(x + a) = 5x² + 10ax + 5a² - 3    ....(i)

As per the question, we have f(x + a) = 5x²+ 30x + 42     ....(ii)

Equating the equations (i) and (ii),

So, 10a = 30

a = 30/10

a = 3

Therefore, the required value of a is 3.

Answer:

y = 0.14 x^2 - 1.43 x + 10.75

Step-by-step explanation

got it correct on the test

The quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have data shown in the table:

It is required to find the quadratic function best models this set of data.

Let the quadratic function is:

y = ax² + bx + c

We can find the values of a, b, and c from the table,  which are constants.

From the table:

a = 10.75

b = -1.43

c = 0.14

The quadratic function is:

y = 10.75x² - 1.43x + 0.14

Thus, the quadratic function best models this set of data is y = 10.75x² - 1.43x + 0.14.

Answer: 2 is less than or equal to x which is less than 4

Answer:

  a) yes; 12/15/17 ~ 20/25/x; SAS

  b) x = 28 1/3

Step-by-step explanation:

The left-side segments are in the ratio ...

  top : bottom = 12 : 8 = 3 : 2

The right side segments are in the ratio ...

  top : bottom = 15 : 10 = 3 : 2

These are the same ratio, and the angle at the peak is the same in both triangles, so the triangles are similar by the SAS postulate.

Normally, a similarity statement would identify the triangles by the labels on their vertices. Here, there are no such labels, so we choose to write the statement in terms of the side lengths, shortest to longest:

  12/15/17 ~ 20/25/x

__

The sides of similar triangles are proportional, so the ratio of longest to shortest sides will be the same in the two triangles. In the smaller triangle, the longest side is 17/12 times the length of the shortest side. The value of x will be 17/12 times the length of the shortest side in the larger triangle:

  x = 17/12 · 20 = 340/12

  x = 28 1/3

Using a linear function, the statement that best describes when she advances to the next phase is: 75 + 3x > 90.

A linear function is modeled by:

y = mx + b

In which:

Considering that she already has 75 points, and earns 3 points for each correct answer, her score is modeled by the following function:

T = 75 + 3x.

She advances to the next phase if she scores over 90 points, hence the statement is:

T > 90

75 + 3x > 90.

Answer:

$533.33

Step-by-step explanation:

$533.33 multiplied by 0.6 = $319.998 which rounds to $320

533.33 ÷ 100 = 5.33 so this is 1 percent

5.33 x 40 = $213.332 which rounds to $213.33

$320 + $213.33 = $533.33
