Step-by-step explanation:
The monthly income of a man is Rs 53000. He deposits 20% of his yearly income in civil investment fund and 10% in charity. If 1 % social security tax should be paid on First Rs 300000and 15% tax is imposed yearly ,how much tax should he pay?
The man needs to pay a total tax of Rs 69780 (3000 for social security and 66780 for yearly tax).
How to find the tax should he pay?To find the tax, let's find the man's yearly income:
Yearly income = Monthly income x 12
Yearly income = 53000 x 12 = 636000
Next, let's find how much he deposits in civil investment fund and charity:
Amount deposited in civil investment fund = Yearly income x 20%
Amount deposited in civil investment fund = 636000 x 0.2 = 127200
Amount deposited in charity = Yearly income x 10%
Amount deposited in charity = 636000 x 0.1 = 63600
Now, let's calculate the total taxable income:
Total taxable income = Yearly income - Amount deposited in civil investment fund - Amount deposited in charity
Total taxable income = 636000 - 127200 - 63600 = 445200
Since the man's taxable income is above Rs 300000, he needs to pay 1% social security tax on Rs 300000:
Social security tax = 1% of 300000 = 3000
Now, let's calculate the yearly tax imposed at a rate of 15%:
Yearly tax = Total taxable income x 15%
Yearly tax = 445200 x 0.15 = 66780
Therefore, the man needs to pay a total tax of Rs 69780 (3000 for social security and 66780 for yearly tax).

Using the intersection of sets we find that A ∩ B = {1, 3}
What is a set?A set is a collection of well ordered items.
Givent hat set A = {x| x is an od number greater than 0 and less than 10} and set B = {1, 2, 3, 4}, we desire to find A ∩ B. We proceed as follows.
First since set A = {x| x is an odd number greater than 0 and less than 10}, its elements are A = {1, 3, 5, 7, 9}
Also, set B = {1, 2, 3, 4}
Since we require A ∩ B which is the intersection of both sets and is the elements that both sets have in common. Since both sets have element 1 and 3 in common, we have that

A van can ferry a maximum of 12 people. By setting up an inequality, find the maximum number of vans that are needed to ferry 80 people
By setting up an inequality, the maximum number of vans that are needed to ferry 80 people are 7 vans.
To find the maximum number of vans needed to ferry 80 people using the given terms, let's set up an inequality. Let's use the variable "v" to represent the number of vans.
Since a van can ferry a maximum of 12 people, we can write the inequality as:
12v ≥ 80
Now, let's solve for "v":
Divide both sides of the inequality by 12.
v ≥ 80/12
Simplify the inequality.
v ≥ 6.67
Since we cannot have a fraction of a van, we need to round up to the nearest whole number:
v ≥ 7
Therefore, the maximum number of vans needed to ferry 80 people is 7 vans.

Therefore, (70+72)/2 = **71 minutes** is the median time. B)42.5 minutes as a result. C,D)The range is determined by deducting the dataset's smallest value from highest value.
A)When the data are organized in order of magnitude, the median time is the middle value. The median in this situation is the average of the 14th and 15th values, which are 70 and 72, respectively. There are 28 data points in this situation. Therefore, (70+72)/2 = **71 minutes** is the median time.
b) The median of the lowest half of the data constitutes the lower quartile (Q1). We must arrange the data in descending order of magnitude before determining the median of the first half of the data in order to determine Q1. is the average of the seventh and eighth values, which are 40 and 45, respectively, in the first half of the data, which consists of 14 values. Q1 = (40+45)/2 = **42.5 minutes as a result.
b) The median of the upper half of the data constitutes the upper quartile (C). We must first organise the data in descending order of magnitude before determining the median of the remaining data in order to determine Q3. Q3 is the average of the seventh and eighth values from the last, which are 90 and 105, respectively, in the second half of the data, which consists of 14 values. Q3 = (90+105)/2 = **97.5 minutes**3 as a result.
d) The range is determined by deducting the dataset's smallest value from highest value.
In this instance, Ben's practise time can be anywhere from **10 minutes** to **180 minutes**. Range then equals maximum value - minimum value, which in this case is 180 - 10 = **170 minutes**
e) Extreme values that are beyond the typical range of a dataset's values are known as outliers. We can use a criterion that states that any value that sits more than 1.5 times the interquartile range (IQR) below Q1 or above Q3 is regarded as an outlier to ascertain whether there are outliers in this dataset. When Q1 is subtracted from Q3, the result is the IQR: Q3 - Q1 = 97.5 - 42.5 = **55 minutes**3. By using this rule, we can see that the dataset contains the outliers **180** and **120** minutes.
IQR stands for what?The term "interquartile range" is IQR. It is a measure of variability that is based on quartilizing a dataset. The first quartile (Q1) is subtracted from the third quartile to determine the IQR. (Q3). It is a representation of the middle 50% of the data's range.

Suppose a friend or family asked you how it could be possible that an annual interest rate is higher than 100%. write out an explanation of what you might say to them
If someone asked me how it could be possible for an annual interest rate to be higher than 100%, I would explain that it is actually quite common in certain situations, particularly in the case of loans with very short terms or loans with high fees.
For example, let's say you borrowed $100 from a lender and agreed to pay back $110 in one week. The lender is essentially charging you 10% interest for the one-week loan period, but if you annualize that rate, it comes out to over 520%. This is because the lender is charging you a very high interest rate for a very short period of time.
Another example would be if you took out a payday loan, which typically have very high fees attached to them. For instance, you might borrow $500 and have to pay back $575 in two weeks. The interest rate on this loan might be calculated as the $75 fee divided by the $500 borrowed, which comes out to 15%. However, if you annualize that rate, it comes out to over 390%.
In both of these examples, the interest rate is very high because the loan term is very short and/or the fees are very high. It's important to note that borrowing at such high interest rates can be extremely costly and can lead to a cycle of debt, so it's generally recommended to avoid loans with high interest rates whenever possible.

If the circumference of a circle is 50. 4 ft, its area is 202.24 sq ft. Correct option is C: 202.24 sq ft.
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. We are given that the circumference is 50.4 ft, so we can solve for the radius:
50.4 = 2πr
r = 50.4 / (2π)
r ≈ 8.02 ft
Now we can use the formula for the area of a circle: A = πr²
A = 3.14 * (8.02)²
A ≈ 202.24 sq ft
Therefore, the answer is option C: 202.24 sq ft.
Alternatively, to find the area of a circle with a circumference of 50.4 ft, we will first find the radius using the formula for circumference (C = 2πr) and then use the formula for the area of a circle (A = πr²). Using π = 3.14:
Solve for the radius (r):
C = 2πr
50.4 = 2(3.14)r
r = 50.4 / (2 * 3.14)
r ≈ 8 ft
Calculate the area (A):
A = πr²
A = 3.14 * (8²)
A = 3.14 * 64
A ≈ 201.06 sq ft
The closest answer among the options provided is 202.24 sq ft. Correct option is C: 202.24 sq ft.

An investor purchases 500 shares of Exxon-mobil stock at $98. 93 per share. His broker charges 2% of the cost of the stock. What is the cost of the stock?
The cost of the stock for the investor would be calculated as follows:
Cost of 1 share = $98.93
Number of shares purchased = 500
Total cost of the stock = Cost per share x Number of shares
Total cost of the stock = $98.93 x 500
Total cost of the stock = $49,465
The broker charges 2% of the cost of the stock, so the broker's fee would be calculated as:
Broker's fee = 2% x Total cost of the stock
Broker's fee = 2% x $49,465
Broker's fee = $989.30
Therefore, the total cost of the stock for the investor including the broker's fee would be:
Total cost of the stock + Broker's fee = $49,465 + $989.30
Total cost of the stock + Broker's fee = $50,454.30
So the cost of the stock for the investor including the broker's fee is $50,454.30.

Patrick buys a tissue box in the shape of a cube. how many cubic centimeters of space do the tissues occupy if the box it half full
The total cubic centimeters of space the tissue box requires is 500 cubic centimeters, under the condition that the box is half full.
The volume of a cube is evaluated by multiplying its length by its width by its height. If all sides of a cube are equal,
we can use the formula
V = s³
here
s = length of one side of the cube.
If we let s be the length of one side of the cube and V be its volume,
V = s³
If we know that the tissue box is half full, then let us consider that half of its volume is occupied by tissues. Then
V' = 0.5 × V
Staging V = s³ in the equation
V' = 0.5 × s³
s = 10 cm (given)
V' = 0.5 × 1000 = 500 cubic centimeters
Hence, if Patrick's tissue box has a volume of 1000 cubic centimeters and it is half full, then the tissues occupy 500 cubic centimeters of space.

When do you hit the water and what is your maximum height above the pool?
The time till you hit the water, given your height above the water, would be 0.76 seconds.
The maximum height above the pool you would get is 15.39 feet.
How to find the maximum height and time ?We are given h ( t ) = - 16 t ² + 5t + 15
You hit the water at 0 so the formula is:
0 = - 16 t ² + 5t + 15
Using the quadratic equation, we can solve:
t = ( - b ± √ ( b ² - 4 ac ) ) / 2a
t = ( - 5 ± √ ( 5 ² - 4 ( - 16 ) ( 15 ) )) / 2 (- 16)
t = (- 5 ± √ 985 ) / -32
t = 0. 76 seconds
The vertex of the parabolic function would be:
= - b / 2a
= - 5 / ( 2 x - 16 )
= 0. 15625 seconds
Maximum height is therefore:
= -16 ( 0. 15625 ) ² + 5 ( 0. 15625 ) + 15
= 15.39 feet

A cat falls from a tree (with zero initial velocity) at time t = 0. How far does the cat fall between t = 0.5 s and t=1.4 s? Use Galileo's formula u(t) = -32t ft/s.
Answer = _______
The distance is negative because it's a fall, so the cat falls 27.36 ft between t = 0.5 s and t = 1.4 s.
To find the distance the cat falls between t = 0.5 s and t = 1.4 s, we need to use the formula for velocity and distance.
we first need to find the position at each of these times using the given formula u(t) = -32t ft/s.
The formula for distance fallen is:
distance(t) = initial position + initial velocity × t + (1/2) × acceleration × t²
Since the cat falls with zero initial velocity and starts from the tree, we can simplify the formula:
distance(t) = (1/2) × acceleration × t²
First, let's find the velocity of the cat at t = 0.5 s and t = 1.4 s using Galileo's formula:
u(0.5) = -32(0.5) = -16 ft/s
and, u(1.4) = -32(1.4) = -44.8 ft/s
Now, we can use the formula for distance:
distance = (velocity at t = 0.5 s + velocity at t = 1.4 s) / 2 x (t = 1.4 s - t = 0.5 s)
⇒ distance = (-16 ft/s + (-44.8 ft/s)) / 2 x (1.4 s - 0.5 s)
⇒ distance = (-60.8 ft/s) / 2 x (0.9 s)
⇒ distance = -27.36 ft/s x s
Therefore, the cat falls 27.36 feet between t = 0.5 s and t = 1.4 s.

The rate of change of revenue per unit is $8 when the unit cost is changing by $8 and the revenue is $4,000.
We are given that the unit cost (C) and unit revenue (R) are related by the equation C = R + 10621.
We want to find the rate of change of revenue per unit, dR/dx, when the unit cost (C) is changing by $8 per unit and the revenue (R) is $4,000.
1. Differentiate the given equation with respect to x: dC/dx = dR/dx
2. Plug in the given values: dC/dx = $8 (cost per unit is changing by $8) R = $4,000 (revenue per unit)
3. Solve for the cost per unit (C) using the equation
C = R + 10621
C = $4,000 + 10621
C = $14,621
