The total income tax imposed on $47,000 is $12,800
How does income tax work?The term "income tax" describes a class of taxes that governments impose on income generated by people and businesses within their territorial jurisdiction.
Taxpayers are required by law to submit an income tax return each year in order to determine their tax obligations.
Income taxes are the main source of funding for governments. They are employed to fund public services, provide residents with goods, and settle debts owing to the government.
A number of states and municipal governments, in addition to the federal government, also require payment of income tax. The Internal Revenue Service is responsible for collecting taxes and enforcing the tax laws in the United States (IRS).
Regarding credits, deductions, and other forms of taxable and reportable income.
Firstly let us break the income tax as per the given condition
Income = 47,000 = 30,000 + 17,000
hence 20% tax is imposed on $30,000 and 40% on $17,000
Total income tax = 20% of 30000 + 40% of 17000
Total income tax = 6000 + 6800 = 12800
hence, The total income tax imposed on $47,000 is $12,800.

Nathan shares out 12 sweets he gives yasmin 1 sweet for 3 sweets he buys how many sweets does nathan get
Given that, Nathan shares out 12 sweets, if he gives Yasmin 1 sweet for 3 sweets he buys, Nathan will get 9 sweets.
How many sweets does Nathan gets?Given that, Nathan shares out 12 sweets, he gives Yasmin 1 sweet for 3 sweets he buys.
Let the sweet be represented by x
For each x sweet for Yasmin, Nathan gets 3x sweets
Hence
x + 3x = 12
We solve for x
4x = 12
x = 12/4
x = 3
Hence;
Yasmin gets x sweet = 3
Nathan gets 3x sweets = 3 × 3 = 9
Given that, Nathan shares out 12 sweets, if he gives Yasmin 1 sweet for 3 sweets he buys, Nathan will get 9 sweets.

On 1st January 2014, Rs1,000,000 was invested and on 1st January of each
successive year Rs500,000 was added to it. What sum will be accumulated by
31st December 2018 if interest is compounded each year at 10% per annum?
The sum accumulated by 31st December 2018 is Rs 4,163,060.00
What is future value?
Future value is the accumulated amount that investments would yield in future period when the amounts invested are added with the total interest earned.
Note in this case that Rs500,000 would be invested subsequently for 4 years( 2015-2018 , January 1st of each year)
We can determine the future value of each investment using the future value formula shown below:
FV=PV*(1+r)^N
PV=amount invested
r=interest=10%
N=number of years that an amount is invested(for instance, the amount invested on 1st January 2014 will earn interest in 2014,2015,2016, 2017 and 2018 i.e. for 4 years)
Total FV=1,000,000*(1+10%)^5+500,000*(1+10%)^4+500,000*(1+10%)^3+500,000*(1+10%)^2+500,000*(1+10%)^1

The value of the limit of the function given when the value of x tends to zero is 0
What is a limit of a function?The limit of a function is a fundamental concept in calculus and analysis concerning the behavior of that function near a particular inputs.
Given the function limit below;
lim x→0 [1 − cos(2x) /x]
Substitute the value of x into the expression to have;
f(0) = 1-cos2(0)/0
f(0) = 1-1/0
f(0) = 0/0 (ind)
Apply the L'hospital rule to have:
lim x→0 [ − (-2sin2x)) /1]
Substitute the value of x into the result
f(0) = 2sin2(0)/1
f(0) = 2(0)
f(0) = 0

Select the correct answer. A new building in the shape of a square pyramid is to be constructed. The slant height will be five times the side length of the base. There will be between 20,000 square feet and 50,000 square feet of construction material used for the outside of the building. What would be the maximum possible side length of the base of the building? Round your answer to the nearest foot. Ο Α. 71 feet OB. 89 feet OC. OD. 45 feet 141 feet
From the information given about the square pyramid, the maximum base length of the building is 67.42 cm.
How do you determine the maximum side length?We are given the following details are:
Base = b
Slant height (l) = 5b
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * b * 5b
Evaluate the product
L = 10b²
The total surface area is calculated using:
T = L + b²
So, we have:
T = 10b² + b²
Evaluate the sum
T = 11b²
Recall that the maximum surface area is 50,000 square feet
So, we have:
11b² = 50000
Divide both sides by 11
b² = 50000/11
Taking the square root of both sides, we have
b = 67.42
Hence, the maximum base length of the building is 67.42 cm

The diameter of an electric cable is normally distributed, with a mean of 0.9 inch and a standard deviation of 0.02 inch. What is the probability that the diameter will exceed 0.92 inch? (You may need to use the standard normal distribution table. Round your answer to three decimal places.)
The probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841
What is probability?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The given parameters are:
Mean = 0.9
Standard deviation = 0.2
Calculate the z-score at x = 0.92 using
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
z = (0.92 - 0.9)/0.02
Evaluate the numerator; subtract 0.9 from 0.92
z = 0.02/0.02
Divide 0.02 by 0.02. This gives
z = 1
The probability is then represented as:
P(x > 0.92) = P(z > 1)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.92) = 0.841
Hence, the probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841

3. Mr. Black's pay increased by 15% when he got a raise, bringing his new salary to $184. What was Mr. Black's original pay?
Answer:
$160
Step-by-step explanation:
115% = $184
100% = X
let X be the original salary
(X is unknown)
115% = $184
100% = X
cross mutiply
115 x X = 100 x 184
115X = 18400
X = 18400 divided by 115
X = $160
therefore,Mr Black's original salary before increased by 15% was $160

Which inequality is represented by the given graph?
C) y ≤ -3x+6
D) y ≥ 3x+6
Answer: c, y ≤ -3x+6
Step-by-step explanation:
for example we could use a point on the graph such as (-2, 0)
now we would insert the numbers into the inequality:
y ≤ -3x+6
= 0 ≤ -3(-2) +6
= 0 ≤ 6+6
= 0 ≤ 12
which is true! therefore it is y ≤ -3x+6
Which inequality is true when x = 4?
A. X+5<_3
B.x/2<3
c.9x>36
D.18<_-8
Answer:
[tex] \sf{b. \frac{x}{2} <3}[/tex]
step by step explanation:
We will try one by one.
A. x + 5 < 3
Step 1. Subtitution Value of x
= 4 + 5 < 3
Step 2. Add by 4 with 5
= 9 < 5
A is wrong because 9 is bigger then 5
B. x/2 < 3
= 4/2 < 3
= 2 < 3
is true because 2 is smaller than 3
C. 9x > 36
9(4) > 36
36 > 36
is wrong, should 36 = 36
D. 18 < 8
is wrong because 18 is bigger than 8
A stadium has 53,000 seats. Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C. The number of seats in Section A
equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,131,000 from each sold-out event. How many seats
does each section hold?
The number section A, section B and section C seats sold are 26500, 14200 and 12300 respectively.
How to use equation to find the total number of seat in each section?The stadium has 53,000 seats.
Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C.
The number of seats in Section A equals the total number of seats in Sections B and C.
Therefore,
a = b + c
a + b + c = 53000
b + c + b + c = 53000
2b + 2c = 53,000
25a + 20b + 15c = 1131000
25(b + c) + 20b + 15c = 1131000
25b + 25c + 20b + 15c = 1131000
45b + 40c = 1131000
Hence,
2b + 2c = 53000
45b + 40c = 1131000
40b + 40c = 1060000
45b + 40c = 1131000
-5b = - 71000
b = - 71000 / -5
b = 14,200
Therefore,
2(14,200) + 2c = 53000
2c = 53000 - 28400
2c = 24600
c = 24600 / 2
c = 12300
Hence,
a = b + c
a = 14200 + 12300
a = 26500

The inverse proportional relationship that models this variation is given as follows:
[tex]y = \frac{10,000}{x}[/tex]
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
An inverse proportional relationship is given as follows:
[tex]y = \frac{k}{x}[/tex]
In this problem, we have an inverse relation in which y(2) = 5000, hence the constant k is found as follows:
[tex]y = \frac{k}{x}[/tex]
[tex]5000 = \frac{k}{2}[/tex]
k = 10,000
Hence the relation is:
[tex]y = \frac{10,000}{x}[/tex]
As stated in the problem, when x = 5, y = 2,000, which we can verify replacing in the relation.
