Answer:

30, 40, 50 which is choice C

Step-by-step explanation:

Square the smaller two values (30 and 40)

30^2 = 900

40^2 = 1600

then add those results

900+1600 = 2500

Notice how 50^2 = 2500 as well. This shows us that 30^2 + 40^2 = 50^2 is a true equation. Both sides lead to the same result 2500. Therefore, a triangle with sides 30, 40, 50 is a right triangle. This is based on the 3-4-5 pythagorean triple, just each side has been multiplied by 10.

The set that represents a Pythagorean triple is 30, 40, 50. Hence, the correct option is C.

Pythagorean triples are sets of three numbers that satisfy the Pythagorean theorem, a² + b² = c², where a, b, and c are the lengths of the sides of a right triangle. To determine which set represents a Pythagorean triple, we need to check if the set's numbers satisfy this theorem.

Looking at the options:

A) 1, 2, 3 does not form a Pythagorean triple.

B) 9, 12, 16 does not form a Pythagorean triple.

C) 30, 40, 50 does form a Pythagorean triple because 30² + 40² = 900 + 1600 = 2500 = 50².

D) 38, 44, 49 does not form a Pythagorean triple.

Therefore, the set that represents a Pythagorean triple is C) 30, 40, 50.

Answer:

$69.75

Step-by-step explanation:

2 jackets cost $46.50 and 5 jackets cost $116.25

The different between 5 and 2 is 3.

So the cost of 3 jackets would be  =$116.25 - $46.50

                                                        = $69.75

Answer:

12 years and 16 years

Step-by-step explanation:

their ages are in the ratio 3 : 4

let Anjali = 3x and Aditya = 4x ← present ages

In 8 years then

Anjali = 3x + 8 and Aditya = 4x + 8, hence

3x + 8 + 4x + 8 = 44 ← sum of their ages in 8 years

7x + 16 = 44 ( subtract 16 from both sides )

7x = 28 ( divide both sides by 7 )

x = 4

Anjali is 3x = 3 × 4 = 12 years old and Aditya = 4x = 4 × 4 = 16 years old

Answer:

0.33 Km/Min

Step-by-step explanation:

Answer:

A. 0

Step-by-step explanation:

23/40 is approximately 1/2.

11/30 is approximately 1/2.

Sine 1/2 - 1/2 = 0, then 23/40 - 11/30 is approximately 0.

By converting the given fractions to a common denominator and performing subtraction, the result falls closest to the benchmark of 0. Hence, the estimated sum or difference of 23/40 and 11/30 is 0.

The given problem is 23/40 - 11/30 and the student has to estimate the result using the benchmarks 0, 1/2, and 1.Steps to resolve the problem:

The benchmark that is closest to 1/4 is 0. So, the estimated sum or difference would be 0.

Final answer:

The distance between the points (–9,2) and (–4,2) is 5 units, calculated as the absolute difference between the x-coordinates since the y-coordinates are equal.

Explanation:

The distance between the points (–9,2) and (–4,2) can be found using the distance formula, which is derived from the Pythagorean theorem. For two points (x1, y1) and (x2, y2) the distance is given by √((x2 - x1)² + (y2 - y1)²). However, because the y-coordinates of the points are the same, we can simplify this to the absolute value of the difference between the x-coordinates.

In this case, the distance is |(–4) - (–9)|, which simplifies to 5 units. There's no need to calculate a square root because there is no vertical change between the points.

Answer:

  =36.36 percent

Step-by-step explanation:

First we need to determine what you saved

11-7 = 4

You saved 4 dollars

Percentage of savings = savings /original price * 100

                                      = 4/11 * 100

                                       =36.36 percent

You saved $4.00 using an RX savings card on a prescription that originally cost $11.00. To find how much you saved in percentage terms, you divide the amount saved by the original cost and multiply by 100. In this case, you saved approximately 36.36%.

You are asking about the percentage savings when using a free RX savings card. To get the savings percentage, you first need to know how much money you saved. In your case, you would have paid $11.00, but you only paid $7.00 with the RX savings card. That means you saved $11.00 - $7.00 = $4.00.

Next, to find the savings as a percentage, you divide the amount saved by the original cost, then multiply by 100 to get a percentage. Here's the calculation:

Savings Percentage = ($4.00 / $11.00) * 100

Doing the division first (4 ÷ 11 = 0.3636), then multiplying by 100, you saved approximately 36.36% with your RX savings card.

Answer:

x < - 17 or x > 7

Step-by-step explanation:

Inequalities of the form | x | > a always have solutions of the form

x < - a or x > a

For | x + 5 | > 12, then

x + 5 < - 12 or x + 5 > 12 ( subtract 5 from both sides of the inequalities )

x < - 17 or x > 7

c. The number of packages of corn purchased.

Step-by-step explanation:

We have been given that a store sells four 1 1/8-pound ears of corn in a package for $3.59. The expression [tex]3.59p[/tex] represents the cost of the corn for a number of packages.

Since the cost of each package of corn is $3.59 and [tex]3.59p[/tex] represents the cost of 'p' packages of the corn. So 'p' represents the number of packages of corn purchased.

Upon looking at our given choices, we can see that option C is the correct choice.

Answer: ₹128

Step-by-step explanation:

To work out the simple interest, you need to work out 8% of ₹20,000 for 2 years, which is 1.08 * ₹20,000 = ₹21,600 in the first year and ₹23,200 in the second year

To work out the compound interest, you need to work out 8% of the new value

1st year: ₹21,600

2nd year: 8% of ₹21,600 = ₹23,328

The difference is ₹23,328 - ₹23,200 = ₹128

Answer:

28%

Step-by-step explanation:

On Thursday night Anna had 20% of the votes, Ivan had 35% of the votes and Elena had 45% of the votes. You can take the number of total votes on Thursday equal to 100, then Anna had 20 votes, Ivan had 35 votes and Elena had 45 votes.

Let x be the number of votes added on Friday. All of them favored Elena, then Elena in total had 45+x votes and the number of all votes became 100+x. In the end Anna had 16%, then

100+x - 100%,

20 - 16%.

Write a proportion:

[tex]\dfrac{100+x}{20}=\dfrac{100}{16},\\ \\16(100+x)=2000,\\ \\1600+16x=2000,\\ \\16x=400,\\ \\x=25.[/tex]

Find the percent of the voters that chose Ivan:

125 - 100%,

35 - y%.

Write a proportion:

[tex]\dfrac{125}{35}=\dfrac{100}{y},\\ \\125y=35\cdot 100,\\ \\y=\dfrac{35\cdot 100}{125}=\dfrac{35\cdot 4}{5}=7\cdot 4=28\%.[/tex]

Answer:

x=-6,  y=3

Step-by-step explanation:

I will use elimination to eliminate the x variable.

Add the two equations.

-3x-3y=9

3x+8y=6

-------------------

   5y  = 15

Divide each side by 5

5y/5 = 15/5

y=3

Now we need to find x

3x+8y=6

Substitute y=3

3x+8*3 =6

3x+24=6

Subtract 24 from each side

3x+24-24 = 6-24

3x = -18

Divide each side by 3

3x/3 = -18/3

x=-6

Jaylan : Water/Juice=(3/4)/(1/5)=15/4

Wanchen : Water/Juice=(2/3)/(1/6)=4/1 or 16/4

Wanchen has a weaker lime flavor because there is more water in her mixture than Jaylan's limeade. Both have the same amount of lime juice (assuming ratio), and Wanchen has more water, making Wanchen have the limeade that has the weaker lime flavor.
