A factory building built for $400,000 depreciates continuously at 10% per annum. What is its value after 7 years?
Answers
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

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%
Answers
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

A miniature golf course charges a flat rate of $5.00 for a putter and then $3.25 for every round of golf played. Write an equation in slope intercept form that shows the cost of playing x number of games.
Answers
slope intercept form is y=mx+b.
In the word problem, you have $5 as basically your non-negotiable fee, meaning $5 would be your y-intercept (also b).
Then you have 3.25, meaning each game is going to cost $3.25.
so for every game you play, it will cost you $3.25 with a add on fee of $5.00
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?
Answers
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.)

Step-by-step explanation:
The question is poorly formatted. However, I will take the parameters as follows:
Given
Perpendicular to: J(-3,2) and L(2,7)
Passes through: (3,0)
Required
Write an equation for the line
First, calculate the slope (m) of JL
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{7-2}{2+3}[/tex]
[tex]m = \frac{5}{5}[/tex]
[tex]m = 1[/tex]
Since the line is perpendicula4 to JL, the slope is:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{1}[/tex]
[tex]m_2 = -1[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 0 = -1(x - 3)[/tex]
[tex]y - 0 = -x + 3[/tex]
[tex]y = -x + 3[/tex]
[tex]y + x = 3[/tex]

The perimeter of a rectangular painting is 280 centimeters. If the length of the painting is 76 centimeters, what is its width?
Answers
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

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?
Answers
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

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
Answers
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.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $21 monthly fee and charges an additional
$0.14 for each minute of calls. The second plan has a $29 monthly fee and charges an additional $0.10 for each minute of calls. For how many minutes of calls
will the costs of the two plans be equal?
Answers
Answer:
200 minutes of calls
Step-by-step explanation:
Let x represent the number of minutes of calls
Set up expressions that represent the costs for each plan:
0.14x + 21 can represent the first plan
0.10x + 29 can represent the second plan
Now, set them equal and solve for x to find when they will be equal:
0.14x + 21 = 0.10x + 29
0.04x + 21 = 29
0.04x = 8
x = 200
So, the costs will be equal with 200 minutes of calls

In the regular pentagon below, the radius is _____, apothem is____, and the side length is______.
Answers
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.
