Answer:
area of hexagon = 600√3 m²
explanation:
apothem² = 20² - 10² = 400 - 100 = 300
apothem of hexagon = √300 = 10√3 m²
area of hexagon = 1/2(6 x 20)(10√3) = 600√3 m²
Answer:
Step-by-step explanation:
One way to find the area of the hexagon is to use the formula [tex]A=\frac{1}{2}ap[/tex], where p is the perimeter and a is the apothem (distance from the center to the midpoint of one side).
The problem says the side length is 20, so the perimeter is 6 x 20 = 120.
The apothem is the distance marked by the dotted line. The rectangles height is [tex]20\sqrt{3}[/tex], so the apothem is half of that, [tex]10\sqrt{3}[/tex].
The area is [tex]\frac{1}{2}\cdot 10\sqrt{3} \cdot 120=600\sqrt{3}[/tex]

A simple random sample from a population with a normal distribution of 103 body temperatures has x = 98.30°F and s = 0.61°F. Construct a 95% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
Answer:
(98.2884 ; 98.3116)
Step-by-step explanation:
Given :
x = 98.30°F and s = 0.61°F
Sample size. n = 103
Zcritical at 95% = 1.96
Using the confidence interval relation :
x ± margin of error
Margin of Error :
Zcritical * s/√n
1.96 * 0.61/√103 = 0.0116
Lower boundary = (98.30 - 0.0116) = 98.2884
Upper boundary = (98.30 + 0.0116) = 98.3116
(98.2884 ; 98.3116)

The expression -x^2 + 70x -600 represents a companys profit for selling x items. For which number of items sold is the companys profit equal to zero?
Answer:
Step-by-step explanation:
-x² + 70x - 600
If we multiply all by -1, we have
x² - 70x + 600
If we factorise this, we have
x² - 10x - 60x + 600
x(x - 10) - 60(x - 10)
(x - 10) (x - 60)
x = 10
x = 60
If the company sells 10, or 60 items, their profit is 0
When Charlotte installed a fence along the 200 foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate. What is the value of x
Answer:
x = 10
Step-by-step explanation:
P = 2(60 + x) + 2(30) = 200
= 120 + 2x + 60 = 200
2x + 180 = 200
2x = 20
x = 10
Find the 11th term of the geometric sequence 6, -18, 54, ...
Answer:
354294
Step-by-step explanation:
Use the formula
[tex]a_{n} = a_{1} r^{n - 1}[/tex]
In your problem [tex]a_{1}[/tex] = 6 r = -3 n = 11
11th term = [tex]a_{11}[/tex] = [tex]6(-3)^{11 - 1} = 6(-3)^{10}[/tex] = 6(59049)
= 354294

The equation of the scatter plot trend line is y = -1700x + 32000 where y is the value of the car in dollars and x is the age of cars in years. Use the trend line equation to predict the value of a car after 7 years.
Answer:
20100
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation
y = -1700x + 32000
Where x is the age of car and y is the value of the car.
Then value after 7 years can be calculated as follows,
y = -1700 (7) + 32000
y = -11900 + 32000
y = 20,100
So, the value of car after 7 years will be 20100.

An item was sold at a loss of 25%. Had it been sold for Rs 21,000 more then the profit would have been
10%. What is the cost price of the item?
[SLC 2068 B]
6B
Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000
which of the following is equivalent to the expression above
c) 2x^2y + 2xy^2
Explanation:
(x^2 y-3y^2+5xy^2)- (-x^2y+3xy^2-3y^2)
(x^2 y+5xy^2 -3y^2)- (-x^2y+3xy^2-3y^2)
x^2 y +5xy^2 -3y^2 + x^2y -3xy^2 + 3y^2
2x^2y + 2xy^2
The option C) 2x²y + 2xy² is equivalent to the given expression (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).
Mathematically, an expression is an admixture of numbers, variables, operations, and functions that are conjoined according to peculiar rules to depict a mathematical calculation or association. It can be supposed to as a mathematical idiom or formula.
By combining numbers, variables, operators, and functions, mathematical expressions can define a broad lea of calculations and associations.
The given expression is (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).
(x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²)
= x²y - 3y² + 5xy² + x²y - 3xy² + 3y²
= 2x²y + 2xy².
Hence, option C) is correct in that 2x²y + 2xy² is equivalent to the given expression.

find the measure of each angle if C D
Answer:
1=72 , 2=108 , 3= 72 , 4=108
Step-by-step explanation:
c parallel to d means that 108 and 1 are adjacent angles , sum 180
therefore ang 1 = 180-108=72
2=108, corresponding angles,
same as above for 3, angle 3= 180-108 =72
2 and 4 are vertically opposite and are equal.
