The royal court of Prince Lemon had dukes, earls, and barons. At the beginning of the Prince's reign, there were 2020 members of the court and each day, one of them killed another one in a duel. Dukes only killed earls, earls only killed barons, and barons only killed dukes. No person won a duel twice. In the end, the only member of the court left alive was Baron Orange. What was the title of the first court member who was killed?
Answer:
The tile of the first member of the court who was killed is an Earl
Step-by-step explanation:
The parameters given are;
Number of members in the court = 2020
Members of the court = Dukes = D, Earls = E and Barons = B
D only killed E, E only killed B and B only killed D
Therefore, the possible duels (combinations) are;
3! = 6 = DD, DE, DB, EB, EE, BB
Given that no one won a duel twice, we have that then DD, BB, and EE could not have occurred as it would result in one winning twice because D only killed E, E only killed B and B only killed D;
The relevant combinations are;
DE, DB, EB
The last person alive was a, baron, B, therefore, he killed a Duke, D, who killed an Earl, E
Given that there were 2020 members, there can be only 2020 - 1 duels = 2019 duels
Following the sequence, BD→DE→EB we have, 2019/3 = 673 complete repiting cycles
So, from the start, we have, a Baron killed an Earl, the Earl killed a Duke, and the Duke killed a Baron, making the tile of the first member of the court to be killed to be an Earl.
The correct answer is : Baron

Find the sum of the digits of the number 6+66+666+6666 + ... +666...66, where the last number contains 100 digits.
Answer:
Sum of the digits of the number
[tex]= ((\frac{60((10)^{100}-1) }{81}) - \frac{600}{9} )[/tex]
Step-by-step explanation:
Step(i):-
Given series
6+66+666+6666 + ... +666...66 up to 100 digits
Taking common '6'
6 ( 1 + 11 +111+ 1111+1111+.................11111....11 100 digits)
Multiply '9' and divisible by'9'
[tex]\frac{6}{9} X9( 1+11 +111 +1111 +1111+ ..........11111..up to .100 digits )[/tex]
Multiply inside '9'
[tex]\frac{6}{9}( 9+99 +999 +9999 +.....+ ..........9999..up to .100 digits )[/tex]
[tex]\frac{6}{9}( (10-1)+(100-1)+(1000-1) +(10,000-1)+.....+ ............up to .100 digits )[/tex]
[tex]\frac{6}{9}( (10)+(100)+(1000) +(10,000)+.....+ ............up to .100 digits ) - ( 1+1+1+1+........up to 100 digits)[/tex]
Step(ii):-
we know that sum of geometric series
[tex]S_{n} = \frac{a(r^{n}-1) }{r-1}[/tex]
we know that
a + a + a+........n terms = n a
[tex]\frac{6}{9}( (10)+(10)^{2} +(10)^{3} +(10)^4+.....+ ............up to .100 digits - (100(1))[/tex] ....(i)
The sum of the 100 digits in geometric series
[tex]S_{100} = \frac{10((10)^{100}-1) }{10-1}[/tex]
Now the equation (i)
The sum of the digits of the number
[tex]= \frac{6}{9} ((\frac{10((10)^{100}-1) }{10-1}) - 100)[/tex]
Final answer :-
Sum of the digits of the number
[tex]= ((\frac{60((10)^{100}-1) }{81}) - \frac{600}{9} )[/tex]
Solve for x. xx−1−1x−2=2x−5x2−3x+2 Select each correct answer. −1 2 3 6
Answer:
(C)x=3
Step-by-step explanation:
We want to solve for x in: [tex]\dfrac{x}{x-1} -\dfrac{1}{x-2}=\dfrac{2x-5}{x^2-3x+2}[/tex]
Take the LCM of the Left Hand Side
[tex]\dfrac{x(x-2)-1(x-1)}{(x-1)(x-2)} =\dfrac{2x-5}{x^2-3x+2}\\\dfrac{x(x-2)-1(x-1)}{x^2-3x+2} =\dfrac{2x-5}{x^2-3x+2}\\$Since we have the same denominator, then:\\x(x-2)-1(x-1)=2x-5\\x^2-2x-x+1-2x+5=0\\x^2-5x+6=0\\$Factorize\\x^2-3x-2x+6=0\\x(x-3)-2(x-3)=0\\(x-3)(x-2)=0\\x-3=0$ or $x-2=0\\x=3$ or x=2[/tex]
However, substituting x=2 does not satisfy the given equation as it would make it undefined.
Therefore x=3
Question: A car drives a distance of 195 miles. The car uses petrol at a rate of about 4.1 miles per litre. The petrol cost £1.14 per litre. Estimate the cost of petrol for the journey. Explanation:
Answer: £54.26
Step-by-step explanation:
Distance travelled = 195 miles
Petrol comsumption
= 195 / 4.1 = 1950 / 41 = 47.6
Cost of petrol = 47.6 x 1.14 = 54.26
Answer:
Approximately 54 pounds and 26 pence (£54.26) or just 54 pounds.
Step-by-step explanation:
The first thing I did to come to this conclusion was creating a table so that I could see that 4.1 miles over 1 liter equals 195 mils over x liters. Once I had done that to get x to equal ~47.6 I plugged that into yet another table where I had 1 liter equal £1.14 which was equal to ~47.6 equal £x. After that I divided the numerators by each other to get ~47.6, I multiplied the £1.14 by 47.6 to get an overall cost of £54.26 overall for the entire car trip.

x less-than-or-equal-to negative 53
x less-than negative 53
x greater-than-or-equal-to negative 53
Answer:
x ≥ -53
Step-by-step explanation:
According to the description of the number line, there is a closed circle on '-53'. This means that we would have to use an 'or equal to' sign.

Everything to the right of the circle is shaded. This would mean that every value that is greater than '-53' will be shaded. So, we would have to use the 'greater than or equal to' sign.
"x ≥ -53" should be the correct answer.
The inequality is x less-than-or-equal-to negative (x ≥ -53). The correct option is B.
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to, > ‘greater than, or < ‘less than.
According to the description of the number line, there is a closed circle on '-53'. This means that we would have to use an 'or equal to' sign.

A bookstore has marked down the price for all of the books in certain series by 15%. How much is the discount on a book that normally costs $18.00? After the discount, how much would the book cost?
Answer fast pls.
Answer:
Discount is $2.70
After-discount price is $15.30
Step-by-step explanation:
To get the after-discount price, multiply $18 by (1.00 - 0.15), or, in other words, multiply $18 by 0.85. The after-discount price is $15.30.
Two ways to find the discount: one is to multiply $18 by 0.15; the other way is to subtract $15.30 from $18.

Mrs.thapa bought 150 kg of oranges.18 kg of oranges were rotten and not fit for selling.If she sold the remaining quantity of oranges at the rate of Rs 80 per kg and gained 10%. Find the rate of cost price of oranges.
Help!!
Answer:
Rs.64
Step-by-step explanation:
Amount of oranges:
150 kgOranges sold:
150 - 18 = 132 kgMoney made:
132* 80 = Rs. 10560Selling price of 150 kg:
10560/150 = Rs. 70.4Cost price:
x+10% = 70.4x*1.1= 70.4x= 70.4/1.1x= Rs.64Cost price of oranges= Rs. 64Answer:
Rs64.00/kg
Step-by-step explanation:
1. Calculate the amount of good oranges
Total amount of oranges = 150 kg
Amount of rotten oranges = 18 kg
Amount of good oranges = 132 kg
2. Calculate the income from the good oranges
[tex]\text{Income} = \text{132 kg} \times \dfrac{\text{Rs80}}{\text{1 kg}} = \text{Rs10 560}[/tex]
3. Calculate the net unit rate of income
The income from the good oranges was Rs10 560.
Based on 150 kg of oranges, the unit rate of income was
[tex]\text{Unit rate of income} = \dfrac{\text{RS10 560}}{\text{150 kg}} = \text{Rs70.40/kg}[/tex]
4. Calculate the original unit rate of cost
Let x = original unit cost. Then
0.10x = 10 % of original unit cost and
1.10x = 10 % over original unit cost
1.10x = RS70.40/kg
x = (RS70.40/kg)/1.10 = Rs64.00/kg
The original unit rate of cost was Rs64.00/kg.
6,000 = bu + 4,000. Given the above equation with constant b, what is the value of 600,000 + 100 bu + 400,000 in millions?
Answer:
1.2 million
Step-by-step explanation:
First multiply the equation by 100. You get:
600,000 = 100bu + 400,000
Now recognize that you can substitute:
600,000 + 100bu + 400,000
= 600,000 + (600,000)
= 1,200,000
That’s 1.2 million.
The value of the equation given is 1.2 millions.
What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, an equation, 6,000 = bu + 4,000, we need to find the value of the equation 600,000 + 100 bu + 400,000,
So, In the equation 1, multiply by 100, we get,
6,000 = bu + 4,000
600000 = 100 bu + 400000
Now, put this in equation 2,
600,000 + 100 bu + 400,000
= 600000 + 600000
= 1200000
= 1.2 millions
Hence, the value of the equation given is 1.2 millions.

solve this system of linear equation. separate the x- and y-values with a comma. 15x+4y=-80 5x+5y=1
Answer:
(x, y) = (-404/55, 83/11)
Step-by-step explanation:
15x + 4y = -80
5x + 5y = 1
Multiplying both side of 2nd equation by 3:
=>
15x + 4y = -80
15x + 15y = 3
Subtracting the 1st equation from 2nd equation:
=>
11y = 83
Dividing both sides by 11 to work out y:
=> y = 83/11
Substituting y back into 2nd equation to work out x:
=> 5x + 5(83/11) = 1
=> 5x + 415/11 = 1
=> 5x = 1 - 415/11
=> 5x = -404/11
=> x = (-404/11)/5
=> x = -404/55
=> (x, y) = (-404/55, 83/11)

In 1995, the USPS approximated that they handled 1.8 x 10^11 pieces of mail. In 2010, the
USPS reported that they handled 1.7 x 10^11 pieces. How many more pieces of mail were
handled in 1995 than in 2010?
Answer:
[tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.
Step-by-step explanation:
We are given that in 1995, the USPS approximated that they handled [tex]1.8 \times 10^{11}[/tex] pieces of mail and in 2010, the USPS reported that they handled [tex]1.7 \times 10^{11}[/tex] pieces.
To find how many more pieces of mail were handled in 1995 than in 2010, we do subtraction of the pieces of mail that were handled in both the years.
Pieces of mail handled in 1995 = [tex]1.8 \times 10^{11}[/tex]
Pieces of mail handled in 2010 = [tex]1.7 \times 10^{11}[/tex]
As it is clear that more pieces of mail were handled in 1995.
So, Pieces of mail handled in 1995 - Pieces of mail handled in 2010 = [tex](1.8 \times 10^{11}) -(1.7 \times 10^{11})[/tex]
= [tex]10^{11} \times (1.8 -1.7)[/tex]
= [tex]10^{11} \times 0.1[/tex] = [tex]1 \times 10^{10}[/tex]
Hence, [tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.

[tex]700 \times (1.008)^5[/tex]
The value expresses the population five years later is (700)(1.008)^5.
We have given that in 1997 the population of a small town was 700.
The annual rate of increase is about 0.8%.
We have to find the population for 5 years

Answer:
[tex]p=80[/tex].
Step-by-step explanation:
The given equation is
[tex]6000+(-25p)=4000[/tex]
We have to isolate the variable p.
The given equation can be written as
[tex]6000-25p=4000[/tex]
Subtract 6000 from both sides.
[tex]6000-25p-6000=4000-6000[/tex]
