In the regular pentagon below, the radius is _____, apothem is____, and the side length is______.
Answer:
radius = 6
apothem = 4.85
side length = 7.05
Step-by-step explanation:
sin 36 =x/6, x= 3.53, side length = 7.05
cos 36 = apothem/6, apothem = 4.85
Therefore, the values of the pentagon is the radius is 6, apothem=4.8 and the side length =3.48.
What is the pentagon?A pentagon is one of the many types of polygon having five sides and five angles. The word 'Pentagon' arises from two words, that are, ‘Penta’ and ‘Gonia,’ meaning five angles.
Let x be the side length of the pentagon.
As per the given information;
Apothem is the line from the center of the pentagon to a side, intersecting the side at 90 degrees right angle.
Sin(36) = x / 6
x = 6 × sin(36)
side length x = 6 × (0.58)
side length x = 3.48
And
cos(36) = apothem / 6
Apothem = 6 cos36
Apothem = 6 (0.80)
Apothem = 4.8
Hence, the radius is 6, apothem=4.8 and the side length x=3.48.

A factory building built for $400,000 depreciates continuously at 10% per annum. What is its value after 7 years?
Answer:
198,634
Explanation:
Substitute the given values into the formula: A = Pe^(−rt), where A represents the future value, P represents the initial (current) value, r represents the rate, and t represnts the time.
A = 400,000e^(-0.10)(7)
A = 198634.12
The value of building depreciation after seven-year is $191,318.76
Depreciation based problem:What information do we have?
Value of building = $400,000
Depreciation rate = 10%
Number of year = 7 year
Value of building after depreciation = P(1-r)ⁿ
Value of building depreiciation = 400,000(1-10%)⁷
Value of building depreciation = 400,000(1-0.1)⁷
Value of building depreiciation = 400,000(0.9)⁷
Value of building depreiciation = 400,000(0.4782969)
Value of building depreciation = $191,318.76

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building
Answer:
The height of the building is of 244.95 feet.
Step-by-step explanation:
We use the Pythagorean Theorem to solve this question.
We have that:
The shadow of 50 feet is one side of the right triangle, while the height h is other side.
The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.
So
[tex]50^2 + h^2 = 250^2[/tex]
[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]
[tex]h = 244.95[/tex]
The height of the building is of 244.95 feet.

what is 20% of 180
please i realy need to answer this
Answer:
36
20 percent * 180 =
(20:100)* 180 =
(20* 180):100 =
3600:100 = 36
Now we have: 20 percent of 180 = 36
Question: What is 20 percent of 180?
Percentage solution with steps:
Step 1: Our output value is 180.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$180=100\%$.
Step 4: Similarly, $x=20\%$.
Step 5: This results in a pair of simple equations:
$180=100\%(1)$.
$x=20\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{180}{x}=\frac{100\%}{20\%}$
Step 7: Again, the reciprocal of both sides gives

The local grocery store has sorted apples by size. The distribution is approximately normal. The large apples have a mean diameter of 10 cm with a standard deviation equal to 0.5 cm. In a bin of 100 large apples, how many can be expected to have a diameter greater than 11.5 cm, three standard deviations above the mean?
Answer:
0
Step-by-step explanation:
Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)

A total of 584 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
584
Step-by-step explanation:
146 adult tickets were sold.
write out your equation first: x+3x=584
4x=584
x=146
Try it out 146+3(146)=584
It worked. That's the solution.
so lets divide the amount of tickets by 4 because there are 4 parts needed in this situation which equals 146 then we know our answer is 146 because the other three parts go to the kids tickets

Jane has just begun her new job as on the sales force of a very competitive company. In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars. Company policy requires that new members of the sales force must exceed an average of more than $100 per contract during the trial employment period. Can we conclude that Jane has met this requirement at the significance level of 90%
Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100
The perimeter of a rectangular painting is 280 centimeters. If the length of the painting is 76 centimeters, what is its width?
Answer:
76x2 = 152
280 - 152 = 128
128 ÷ 2 = 64
Answer:
the width is 64cm
Step-by-step explanation:
a rectangle has 4 sides, each set of opposite sides are congruent, perimeter is the distance around an object, so we need to add up all 4 sides and it should equal 280cm, we know one side is 76, so our equation should look as follows:
76 + x + 76 + x = 280
2x + 152 = 280
2x = 128
x=64
you can check the answer but substituting 64 for x and seeing if it comes out to 280
76+64+76+64=280
280=280
find the HCF of 120,140, 180
Answer:
The Highest common factor of 120,140,180 is ( HCF) = 20
Step-by-step explanation:
Explanation:-
Given numbers 120,140,180
120 = 60 × 2
= 30 × 2× 2
= 15 × 2×2×2
= 5×3× 2×2×2
140 = 70 × 2
= 10 × 7× 2
= 5× 2× 7× 2
180 = 90 × 2
= 30×3×2
= 5 × 6 × 3× 2
= 5 × 2× 3× 2 × 3
The Highest common factor of 120,140,180 is 5 ×2×2 = 20
