during a festive season a shop offered a discount of 20 percent on the marked price of all items find the SP of 3 trousers mardep at rs 1800 each and two t shirts marked at rs 550 each

Answers

Answer 1

Think of the retail price as the whole price or 100%. Since the items are discounted 20% you end up paying 80% of the retail price for each item. 80% of the retail price is the sale price.

TROUSERS
We need to find 80% of 1800. Percent means out of 100 so we can represent it using [tex] \frac{80}{100} [/tex] or .80 whichever is easier for you to work with. Multiply this by 1800 and you have your sales price for 1 trouser. That is, the sales price for a trouser is (1800)(.8) = 1440.

SHIRTS
Same as we did for trousers we multiply the price of a shirt (550) by (.8) to get the sale price. It is 440.

3 TROUSERS AND 2 SHIRTS
The sales price for 3 trousers and 2 shirts is (3)(1440) + (440)(2) = 5200

NOTE
I noticed that you didn't include currency (dollars, pounds, euros, for example). If these are dollars then the price of a trouser might be $18.00 as opposed to 1800 which seems really high. Similarly I would expect 18,00 Euros as opposed to 1800 Euros for a pair of pants. If this is the case take the answers given above and merely insert a decimal point to spaces from the left (or in Europe and other parts of the world a comma).

A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle

Answers

We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
[tex]60^2+63^2 = 87^2[/tex]
[tex]7569 = 7569[/tex]

This is, indeed correct, thus, this is a right triangle.

Since the given lengths satisfied the Pythagorean theorem then the given triangle is a right angled triangle.

Use the concept of the triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

And the Pythagoras theorem for a right angled triangle is also defined as:

(Hypotenuse)²= (Perpendicular)² + (Base)²

The given length of sides are:

60 centimeters, 63 centimeters, and 87 centimeters.

Now take,

Hypotenuse = 87 cm

Base = 63 cm

Perpendicular = 60 cm

Apply the Pythagorean theorem,

87² = 60² + 63²

Calculating it,

7569 = 7569

Since the given sides satisfied the Pythagorean theorem,

Hence,

The triangle is a right angled triangle.

Attila the Hun was a ruler of the Hunnic Empire. The Romans feared him greatly until his death since he made quite a habit of invading. The Romans no longer feared him after his death in 453. Let xxx represent any year. Write an inequality in terms of xxx and 453 that is true only for values of xxx that represent years after the year that Attila died.

Answers

453< x if the value of x is greater than 453 then the Romans didn't fear him because after 453 he was dead. 453 and any number smaller than that would be times in his life that he would have been feared.

Attila the Hun died in 453.

Let x represents the year.

So the inequality for will be 453<x.

Explanation:

Here x will be smaller than 453 because Hun was dead in 453. So 453 and any number smaller than that would be the times in his life that he would have been feared.

Suppose the value of x is greater than 453, then the Romans didn't fear him because after 453 he was dead.

A basketball coach keeps track of points scored per game for all of her players. she gives a trophy to the player with the highest mean score at the end of the season. which of the following justifies why she uses the mean instead of the median?

B. she wants to take unusually good or bad games into account

C. she wants to remove unusually good and bad games from consideration.

Answers

Answer:

B lol

Step-by-step explanation:

don't ask me

Final answer:

The coach uses the mean to track player scores because it incorporates all scores, including unusually high or low ones, giving credit for exceptional performances. The median would only consider the middle score and discard extremes.

Explanation:

The basketball coach uses the mean instead of the median to keep track of points scored per game for all her players because she wants to take unusually good or bad games into account (option B). The mean is calculated by adding up all the scores and dividing by the total number of games, so each game's score has a direct impact on the result. In contrast, the median only considers the middle score and discards extreme values, making it less sensitive to unusually high or low scores.

For instance, if a player scores 30 points in one game and then 10 points in each of the next nine games, their mean score would be (30 + 9*10)/10 = 13 points per game. In contrast, their median score would be 10 points per game because that's the middle value when all scores are listed in numerical order. Therefore, the choice to use the mean allows the coach to give credit for exceptional performances.

Answer:

The owner's prediction is Not Correct .. Based on the samples, about 35% of the books sold each week are fiction books.

Step-by-step explanation:

The owner of a bookstore predicts that over 50% of the books she sells each week are fiction books.

Based on the table of randomly selected sample we see that in week 1 there are 50 fiction books out of total 150 books.

so, the percentage of fiction books are:

[tex]\dfrac{50}{150}\times 100\\\\=33.33\%[/tex]

Similarly in the second week i.e. week 2 the number of fiction books are 55 out of 150 books so, the percentage of fiction books in week 2 are:

[tex]\dfrac{55}{150}\times 100\\\\=36.66\%[/tex]

Hence,

The owner's prediction is Not Correct .. Based on the samples, about 35% of the books sold each week are fiction books.

The standard tip in a restaurant is 15% of the bill before tax. Many people in California find the tip by doubling the sales tax, which is 8.25%. By how many cents does this exceed the standard tip on a bill of 60% before tax?

Answers

To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.

The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.

Answer:

90¢

Step-by-step explanation:

The percent paid by many people in California is [tex]$16.50\%$, or $1.50\%$[/tex] more of the bill than the standard tip. Thus the total difference is [tex]$\$60\cdot 0.015 = \$0.90$[/tex], or [tex]$\boxed{90}$[/tex] cents.

Explanation:
The square of any number can be obtained by multiplied the number by itself.
In other words:
square of x = x² = x * x

For the given, we want to get the square of 8. This means that we will multiply 8 by itself.
Therefore:
square of 8 = 8² = 8 * 8 = 64

Hope this helps :)

Answer:

[tex]8^2=8\times 8=64[/tex]

Step-by-step explanation:

We have been given a number. We are asked to find the square of our given number.

We know that the square means a quantity multiplied by itself. When a number (a) is multiplied by itself, we can write that number by raising to second power as: [tex]a\times a=a^2[/tex]

Since we need to find the square of 8, so we can write it as:

[tex]8\times 8=8^2[/tex]

[tex]64=8^2[/tex]

Therefore, the square of 8 is 64.

Quadrilateral ABCD is inscribed in this circle.

What is the measure of ∠A ?

Enter your answer in the box.

Answers

arcDAB = 2*m∠C = 2*121 = 242°
arcDCB = 360° - arcDAB = 360 - 242 = 118°
m∠A = arcDCB/2 = 118/2 = 59°

One of the circle theorems is that opposite angles in a cyclic quadrilateral sum to 180°.
We can see that C is opposite to A, so in other words angle C + angle A = 180°. This can quickly be solved:
121+A=180
Minus 121 on both sides
A=59°

peggy is five years older than peter and susan is two years younger than peter the sum of their ages is 15 years how old is each child

Answers

Peter is 4 years old, Peggy is 9 years old, and Susan is 2 years old.

Let's denote Peter's age as ( P ) years. Based on the given information:

1. Peggy is five years older than Peter, so Peggy's age is ( P + 5 ) years.

2. Susan is two years younger than Peter, so Susan's age is ( P - 2 ) years.

The sum of their ages is given as 15 years:

[tex]\[ P + (P + 5) + (P - 2) = 15 \][/tex]

Now, simplify and solve for $ P $:

[tex]\[ 3P + 3 = 15 \]\[ 3P = 12 \]\[ P = 4 \][/tex]

So, Peter is 4 years old. Using this information, we can find Peggy's age[tex]($ P + 5 $) and Susan's age ($ P - 2 $):[/tex]

- Peggy: ( 4 + 5 = 9 ) years old

- Susan: ( 4 - 2 = 2 ) years old

Therefore, Peter is 4 years old, Peggy is 9 years old, and Susan is 2 years old.

This is an example of a quadratic equation. It is in the shape of an upside down parabola.

Our goal is to solve the following equation: 0 = -16x^2 - 16x + 9

To do this, we can use the quadratic formula. The variables are:
a = -16

Marvin lives in Stormwind City and works as an engineer in the city of Ironforge. In the morning, he has 333 transportation options (teleport, ride a dragon, or walk) to work, and in the evening he has the same 333 choices for his trip home. If Marvin randomly chooses his method of travel in the morning and in the evening, what is the probability that he teleports at least once per day?

Answers

The event "Atleast once" is the complement of event "None".

So, the probability that Marvin teleports atleast once per day will the compliment of probability that he does not teleports during the day. Therefore, first we need to find the probability that Marvin does not teleports during the day.

At Morning, the probability that Marvin does not teleport = 2/3

Likewise, the probability tha Marvin does not teleport during evening is also 2/3.

Since the two events are independent i.e. his choice during morning is not affecting his choice during the evening, the probability that he does not teleports during the day will be the product of both individual probabilities.

So, the probability that Marvin does not teleport during the day = [tex] \frac{2}{3}*\frac{2}{3}=\frac{4}{9} [/tex]

Probability that Marvin teleports atleast once during the day = 1 - Probability that Marvin does not teleport during the day.

Probability that Marvin teleports atleast once during the day = [tex] 1-\frac{4}{9}=\frac{5}{9} [/tex]

Answer:

5/9

Step-by-step explanation:

The chances he teleports in the morning is 2/3

Same for the evening.

so mulitply the two choices 2/3 * 2/3= 4/9

Then add 1 to account for teleports ONCE a day

1+4/9= 5/9
