Find the area of the regular hexagon round answer to the nearest tenth.
Answers
Answer:
280.6 [tex]m^2[/tex]
Step-by-step explanation:
find the length of each side:
you're only given h = 9 m
the formula for h is [tex]h=\frac{\sqrt{3} }{2} *a[/tex], where a is a side length of the hexagon
plug h in:
[tex]9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\[/tex]
a ≈ 10.392 m
now find the area of a triangle:
1/2 (10.392)(9) = 46.764 [tex]m^2[/tex]
multiply that by 6 and you get 280.584 ≈ 280.6 [tex]m^2[/tex]
you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: [tex]\frac{3\sqrt{3} }{2} *a^2[/tex]

Step-by-step explanation:

→[tex]16x=240[/tex] →[tex]x=15[/tex]
∠[tex]YZU=10*15+9=159[/tex]
[tex]---------[/tex]
hope it helps...
have a great day!!
Answer:
159°
Step-by-step explanation:
A circle measures 360°. We can use this knowledge to find the unknown angles.
(10x + 9) + (6x - 13) + 34 + 90 = 360
Combine like terms and solve for x.
16x + 120 = 360
16x = 240
x = 15
So, we have found the value of x, and can now find m∠YZU.
10(15) + 9 = m∠YZU
m∠YZU = 159°
We can ascertain that this is the answer by plugging in x for the initial equation we created.
(10(15) + 9) + (6(15) - 13) + 34 + 90 = 360
159 + 77 + 34 + 90 = 360 It works!

The diameter of a circle is 18m . Find its circumference in terms of pi?
Answers
Answer:
The circumference of a circle =πd = π×18 =18π m
The diameter of a circle is 18 m. Find its circumference in terms of π.
Solution:-Diameter of a circle = 18 m. (Given)
Radius (r) of a circle = 18/2 = 9 m.
We know,
[tex] \dag [/tex] Circumference of a circle is 2πr.
So, It's circumference is (2 × π × 9) m.
It's circumference is 18π m.

The measure of the unknown angle is 70 degrees
In circle geometry, there is a theorem that states that the angle at the centre of a circle is twice the angle at the circumference
Given the following parameters;
Angle at the circumference = x
Angle at the centre = 140 degrees
Using the given theorem;
140 = 2x
Swap
2x = 140
x = 140/2
x = 70
Hence the measure of the unknown angle is 70 degrees

A CD manufacturer wanted to determine which of two different cover designs for a newly released CD will generate more sales. The manufacturer chose 70 stores to sell the CD. Thirty-five of these stores were randomly assigned to sell CDs with one of the cover designs and the other 35 were assigned to sell the CDs with the other cover design. The manufacturer recorded the number of CDs sold at each of the stores and found a significant difference between the mean number of CDs sold for the two cover designs. Which of the following gives the conclusion that should be made based on the results and provides the best explanation for the conclusion?
A. It is NOT reasonable to conclude that the difference in sales was caused by the different cover designs because this was not an experiment.
B. It is NOT reasonable to conclude that the difference in sales was caused the different cover designs because there was no control group for comparison.
C. It is NOT reasonable to conclude that the difference in sales was caused the different cover designs because the 70 stores were not randomly chosen.
D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores.
E. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the sample size was large.
Answers
Answer:
The statement that gives the best conclusion that should be made based on the results and provides the best explanation for the conclusion is option D;
D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores
Step-by-step explanation:
The data given in the question are presented as follows;
The particulars the CD manufacturer wants to determine = The CD cover design that will generate more sales
The mode of selection of the stores for the test = Random selection
The number of stores in each group of stores, n = 35 stores
The number of sets of stores tested = 2 sets of stores
Let [tex]\overline x_1[/tex] represent the mean number CDs sold at one set of stores and [tex]\overline x_2[/tex] represent the mean number CDs sold at the other set of stores
The null hypothesis, H₀; [tex]\overline x_1[/tex] = [tex]\overline x_2[/tex]
The alternative hypothesis, H₀; [tex]\overline x_1[/tex] ≠ [tex]\overline x_2[/tex]
Given that the statistical analysis shows that the difference in mean between the two sets of randomly selected stores is significant, we therefore should reject the null hypothesis and accept the alternative hypothesis that there is a significant difference in CD sale attributable to the difference in cover design as the CDs having on of two cover design where assigned randomly to the stores.

Lin has a die with 6 sides, each labeled 1, 2, 3, 4, 5, and 6. What is the probability that she will roll a 3? *
Answers
Answer:
Probability of rolling number 3 = [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Lin has a die with 6 sides.
Each side of the die is labeled with 1, 2, 3, 4, 5 and 6.
Since, probability of rolling any number = [tex]\frac{\text{Favorable event}}{\text{Total number of events}}[/tex]
Therefore, probability of rolling number 3 = [tex]\frac{\text{Favorable event}}{\text{Total number of events}}[/tex]
Favorable event of getting 3 in single roll = 1
Total events that can happen in one roll = 6
Therefore, probability of rolling number 3 = [tex]\frac{1}{6}[/tex]

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( x - 1 ) ( 2x - 8 ) be equation (1)
On simplifying the equation , we get
A = x ( 2x - 8 ) - 1 ( 2x - 8 )
A = x ( 2x ) - x ( 8 ) - 2x + 8
On further simplification , we get
A = 2x² - 8x - 2x + 8
A = 2x² - 10x + 8
Therefore , the value of A is 2x² - 10x + 8
Hence , the equation is A = 2x² - 10x + 8
