Answer:

Approximately 26.4 pounds

Step-by-step explanation:

1 kilogram is approximately 2.2 pounds.

12 * 2.2 =

26.4

Answer:

it weighs 33.0693

Step-by-step explanation:

multiple the mass value by  2.205

as you should know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\sqrt{x}-5\implies \stackrel{\textit{quick switcheroo}}{x=\sqrt{y}-5}\implies x+5=\sqrt{y} \implies (x+5)^2=y \\\\\\ \stackrel{F~O~I~L}{(x+5)(x+5)}=y\implies x^2+10x+25=\stackrel{f^{-1}(x)}{y}[/tex]

Step-by-step explanation:

The period of the tangent function is given by:

b) 2pi

It is the distance between the repetition of the function. If a function is defined on an interval and said to be periodic, the period is the length of the interval.

In this problem, the interval is [tex][-\pi, \pi][/tex], and after that the values will start repeating, hence the period is:

[tex]p = \pi - (-\pi) = 2\pi[/tex]

Thus option b is correct, as the period is of [tex]2\pi[/tex].

Answer:

Ans.=250 21/50

Step-by-step explanation:

54.2%=542/100

=271/50

=250 21/50

to get any percent value to a decimal or fraction format, we simply divide it by 100, first off let's make 54.2 to a fraction and then divide by 100.

[tex]54.\underline{2}\implies \cfrac{542}{1\underline{0}}~\hspace{10em}\cfrac{542}{10}\div 100\implies \cfrac{542}{10}\cdot \cfrac{1}{100}\implies \cfrac{271}{500}[/tex]

A regular hexagon has 6 congruent sides.

The dimension of the rectangle is 8 inches by [tex]4\sqrt 3[/tex] inches

Start by calculating the value of x using the following cosine ratio

[tex]\cos(60) = \frac{x}{4}[/tex]

Make x the subject

[tex]x = 4 * \cos(60)[/tex]

Evaluate cos(60)

[tex]x = 4 * 0.5[/tex]

[tex]x = 2[/tex]

So, the dimension of the rectangle is:

[tex]Length = 2x + 4[/tex]

[tex]Width = 2x\sqrt 3[/tex]

This gives

[tex]Length = 2 * 2 + 4[/tex]

[tex]Length = 8[/tex]

[tex]Width = 2 * 2\sqrt 3[/tex]

[tex]Width = 4\sqrt 3[/tex]

Hence, the dimension of the rectangle is 8 by [tex]4\sqrt 3[/tex]

Answer: <BOC and <COD are supplementary. The sum of their angle measures is 180 degrees.

Step-by-step explanation:

Since angles BOC and COD both form a horizontal line (line BOD) when added together, the two angles are supplementary. Supplementary angles always equal 180 degrees when added together because they form a straight line, or half of a circle.

Therefore, <BOC and <COD are supplementary, and the sum of their angle measures is 180 degrees.

The probability that an 8th grader will be selected from selection of a student for the considered case is 1/3

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For this case, it is given that:

To find: Probability that an 8th grader will be selected

Take an event E as:
E = event of selecting an 8th grader.

Then, as there are 4 such students, so event E can be done in 4 ways.

Total students are 12, so selecting a student (whether E occurs or not) is do-able in 12 ways.

As all the students are equally likely, we can use the above definition of probability of an event E, and therefore, we get:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{4}{12} = \dfrac{1}{3}[/tex]

Thus, the probability that an 8th grader will be selected from selection of a student for the considered case is 1/3
