please what is measurement BAC

Answer:

Step-by-step explanation:

ratio of 5:7 means that 5/(5 + 7) = 5/12 are boys and 7/(5 + 7) = 7/12 are girls

(5/12)(36) = 15 boys

(7/12)(36) = 21 girls

21 - 15 = 6 more girls than boys.

Answer:

here's what we know:

a + b = 72

a - b = 26

We can use the elimination method to solve this problem:

a + b = 72

a - b = 26

---------------

2a = 98

Divide both sides by 2:

a = 49

So we now have:

49 + b = 72

and:

49 - b = 26

Subtract 49 from both sides:

b = 23

and

-b = -23 (multiply both sides by -1) → b = 23

Answer:

X - X/12 = 14 2/5 = 72/5        1/12 of X is lost in roasting

(12 X - X) / 12 = 72/5

11 X / 12 = 72/5

11 X = 864 / 5

X = 864 / 55

Or 864 / 55 = 15 39/55 lbs

Answer:

16 lbs

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

I think you're talking about simplifying/reducing the fraction.

You would not do that in this case because the numbers 7 and 16 have no common factors besides 1.

The answer is already in its lowest/reduced form. You do not divide.

Please let me know if this was not what you were talking about!

Using the fundamental counting theorem, it is found that 107,016 different choices are possible.

Fundamental counting theorem:

States that if there are n things, each with [tex]n_1, n_2, …, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem:

Then, applying the theorem:

[tex]N = 7(24)(7)(13)(7) = 107016 [/tex]

107,016 different choices are possible.

Step-by-step explanation:

Answer:

0.5/ 10.2

Well its basically

Well first you gotta make sure the 10.2 is a whole number in order to divide

so we can multiply by 10

that turns it into 102

Now what we do do 10.2 we do to 0.5 to make it equal which makes0.5*10=5

Now its easier so its 5/102

Now we just divide normally

Answer:

  (-1, 4)

Step-by-step explanation:

Rotation 180° negates both coordinates:

  (x, y) ⇒ (-x, -y)

The direction (clockwise or counterclockwise) is irrelevant. It is the same as reflection across the center of rotation (the origin).

  (1, -4) ⇒ (-1, 4) . . . . after rotation 180°

Step-by-step explanation:

The features of the sine function in this problem are given as follows:

Amplitude: 2.

Midline: y = -4.

Period: 3 units.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Here, we have,

The equation is given as follows:

y = 2sin(2πx/3) - 4.

we have to define the sine function:

The standard definition of the sine function is given as follows:

y = Asin(B(x - C)) + D.

For which the parameters are given as follows:

A: amplitude.

B: the period is 2π/B.

C: phase shift.

D: vertical shift.

The function has a minimum value of -6 and a maximum value of -2, for a difference of 4, hence the amplitude is given as follows:

2A = 4.

A = 2.

Without vertical shift, a function with amplitude of 2 would oscillate between -2 and 2, while this one oscillates between -6 and -2, hence the vertical shift is given as follows:

D = -4.

The shortest distance between repetitions can be given by 2 - (-1) = 3, hence the period is of 3 units and the coefficient B is given as follows:

2π/B = 3

B = 2π/3.

The function is at it's midline at the origin, hence it has no phase shift, and thus the equation is given as follows:

y = 2sin(2πx/3) - 4.
