Answer:

A. 24

Step-by-step explanation:

n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction

n/54 = 4/9

Cross product

n * 9 = 54 * 4

9n = 216

n = 216/9

n = 24

A. 24

Check:

n/54 = 4/9

24 / 54

Divide through by 6

= 4/9

Answer:

$24

Step-by-step explanation:

$36 divided by 3 = 12

12 x 2 = 24

24 = 2/3 of 36

Answer: I used the Pythagorean theorem and got 6.24, but if I was supposed to use another method, just let me know.

The formula is a^2+b^2=c^2

a=5

c=8

b=?

5^2+b^2=8^2

25+b^2=64

b^2=39

b=6.24,

(If it doesn't work, put x=6.24, x=-6.24. It can be both technically, but most teachers ask only for the first one. )

9514 1404 393

Answer:

  (a, b, c) = (-0.425595, 11.7321, 2.16667)

  f(x) = -0.425595x² +11.7321x +2.16667

  f(1) ≈ 13.5

Step-by-step explanation:

A suitable tool makes short work of this. Most spreadsheets and graphing calculators will do quadratic regression. All you have to do is enter the data and make use of the appropriate built-in functions.

Desmos will do least-squares fitting of almost any function you want to use as a model. It tells you ...

  a = -0.425595

  b = 11.7321

  c = 2.16667

so

  f(x) = -0.425595x² +11.7321x +2.16667

and f(1) ≈ 13.5

Additional comment

Note that a quadratic function doesn't model the data very well if you're trying to extrapolate to times outside the original domain.

Given:

The equation of a line is

[tex]y=-\dfrac{2}{3}x+2[/tex]          ...(i)

The perpendicular line passes through the point (-1,4).

To find:

The equation of the perpendicular line.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]            ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

[tex]m=-\dfrac{2}{3}[/tex]

Product of slopes of two perpendicular lines is -1.

Let the slope of perpendicular line is [tex]m_1[/tex].

[tex]m\times m_1=-1[/tex]

[tex]-\dfrac{2}{3}\times m_1=-1[/tex]

[tex]m_1=\dfrac{3}{2}[/tex]

The slope of the perpendicular line is [tex]m_1=\dfrac{3}{2}[/tex] and it passes through the point (-1,4). So, the equation of the line is:

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-4=\dfrac{3}{2}(x-(-1))[/tex]

[tex]y-4=\dfrac{3}{2}(x+1)[/tex]

[tex]y-4=\dfrac{3}{2}x+\dfrac{3}{2}[/tex]

Add 4 on both sides.

[tex]y-4+4=\dfrac{3}{2}x+\dfrac{3}{2}+4[/tex]

[tex]y=\dfrac{3}{2}x+\dfrac{3+8}{2}[/tex]

[tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex]

Therefore, the equation of required line is [tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex].

Answer: $26,470

Step-by-step explanation:

Total costs are all the expenses that have to be paid by your business to keep it producing.

In this case that figure is:

Total cost = Rent + Phone bill + Electric bill + Heat bill + own salary + Wages

= 1,000 + 120 + 150 + 200 + 5,000 + 20,000

= $26,470

Answer:

Angle 2 = Angle 4 = 76

Step-by-step explanation:

Here, we want to get the measures of angle 2 and angle 4

From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)

The reason for this is because both angles are same side interior angles

Thus,

angle 2 + angle 5 = 180

angle 2 = 180 - angle 5

angle 2 = 180 -104

angle 2 = 76

Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles

Thus, angle 2 = angle 4 = 76

Answer:

$52.50

Step-by-step explanation:

1. You take 550 and divide by 5.

2. Then you would takw that number (105) and multiply by 2 (210)

3. Then you take 210 and divide by 4 which equals 52.5

4. The answer is 52.5 because she takes 1/4 of the 2/5 for vacation a month.

Answer:

7.5

Step-by-step explanation:

90÷12 = 7.5.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. Division is the reciprocal of multiplication.

90 divided by 12,

on dividing 90 by 12 we get,

7.5 as quotient and 6 as remainder.

Quotient is the number of times a division is completed fully, while the remainder is the amount left that

Hence, 90÷12 = 7.5.

Answer:

She spent 7/15 of the day working on her project.

Step-by-step explanation:

Well we cant get a clear answer with the fractions 1/3 and 1/5, so we are going to have to turn them into equivalent fractions.

3 and 5 both have 15 LCD so:

1/3 x 5/5 = 5/15

1/5 x 3/3 = 3/15

5/15 + 3/15 = 8/15

15/15 - 8/15 = 7/15

She spent 7/15 of the day working on her project.

A = 735 + 294

Answer:

The sequence is 2, 4, 8, 16, 32

The next answer is 2

Step-by-step explanation:

The missing terms of the required sequence are 8, 16 and 32 respectively.

In a geometric sequence, the ratio of two consecutive terms are always equal.

The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .

The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)

The given sequence is 1, 3, 7, 15, 31, 63...

Then, the sequence formed by subtracting the consecutive terms are given as,

3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....

Which can be rewritten as,

2, 4, 8, 16, 32......

It is a geometric sequence as ratio of the consecutive terms are equal,

4/2 = 8/4 = 16/8

Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......
