A box of chocolates shaped like a regular hexagon is placed snugly inside of a rectangular box as shown in the figure.If the side length of the hexagon is 4 inches, what are the dimensions of the rectangular box? (30°-60°-90° )
A regular hexagon has 6 congruent sides.
The dimension of the rectangle is 8 inches by [tex]4\sqrt 3[/tex] inches
How to determine the length of the rectangleStart 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]

(a) Write 54.2% as a fraction.
Give your answer in its simplest form.
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]
Twelve students have an equally likely chance of being selected in a drawing at school. Eight are 7th graders and four are 8th graders. What is the probability that an 8th grader will be selected?
The probability that an 8th grader will be selected from selection of a student for the considered case is 1/3
How to calculate the probability of an event?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:
Twelve students have an equally likely chance of being selected in a drawing at school.Out of those 12, number of 7th grader = 8Out of those 12, number of 8th grader = 4To 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

a path of width 2 meters runs around and outside a square plot of side 10 meters. then the area of the path is what square meters
I am 7th class
Answer:
area of the path = 96 m²
Step-by-step explanation:
See attached diagram.
The green square is the square plot of side 10 m.
The grey is the path of width 2 m running around the outside of the square.
The easiest way to calculate the area of the path is to work out the entire area of the path and square plot, then subtract the area of the green square from it.
Area of a square = (side length)²
Area of green square = 10² = 10 x 10 = 100 m²
We are told that the width of the path is 2 m, so the side length of the square incorporating the path AND the green square will be:
side length of green square + 2 + 2 = 10 + 2 + 2 = 14 m
Therefore, entire area = 14² = 14 x 14 = 196 m²
To find the area of the path only:
entire area - area of green square = 196 - 100 = 96 m²
So the area of the path is 96 m²

Describe the relationship between BOC and COD what is the sum of their angle measures
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.
