Final answer:

To determine the number of different arrangements of four books, we calculate the permutation 4!, which equals 24. Hence, there are 24 different ways to arrange the four books.

Explanation:

The question asks about the number of different ways to arrange four books on a shelf, assuming the order of the books makes a difference. This problem is an example of a permutation, where the arrangement of a set of items is important.

To calculate this, we use the formula for permutations, which is n!, where 'n' is the number of items to arrange. In this case, we have four books, so we calculate 4! (which is shorthand for 4 × 3 × 2 × 1).

Therefore, 4! = 24. There are 24 different ways to arrange the four books on the shelf.

The greatest whole number that rounds to 2,500 to the nearest hundred is 2549.

To answer this question, we need to understand how rounding works. When we round to the nearest hundred, any number that falls exactly in the middle or above will round up to the next hundred. Any number that falls below the middle will round down to the previous hundred. The middle point between 2400 and 2500 is 2549. Therefore, 2549 would be the greatest whole number that rounds down to 2500 when rounded to the nearest hundred.

Answer:

s = 45w

Step-by-step explanation:

Jeremiah is saving money for a tutoring job.

He saved $135 after 3 weeks.

Therefore, his saving per week = [tex]\frac{\text{Total amount}}{\text{Number of weeks}}[/tex]

= [tex]\frac{135}{3}[/tex]

= $45

If he works for w weeks then at the same rate total amount saved by him will be

= $45w

If this amount is equal to $s then equation that represents the total saving after w weeks will be

s = 45w

The percentage of student absences that occurred on Tuesday is approximately 24%.

The circle graph represents the distribution of student absences by day of the week. The central angle for the Tuesday slice is given as 86.4°. To find the percentage of absences on Tuesday, we use the formula: (Central Angle / Total Central Angle) * 100%. In this case, (86.4° / 360°) * 100% ≈ 24%. Therefore, approximately 24% of the student absences occurred on Tuesday.

The central angle represents the proportion of the total absences attributed to each day. A circle has a total central angle of 360°, and the central angle for each day is a fraction of this total. Tuesday's central angle of 86.4° indicates that Tuesday's absences make up 24% of the total absences.

This method applies because the circle graph represents a whole, and each sector's central angle corresponds to its share of the total. Consequently, the calculation accurately reflects the percentage of absences on Tuesday in relation to the entire week.

Students who use PEMDAS often think that multiplication must come before division but that's not necessarily the case. If division appears before multiplication when your reading the problem from left to right, do your division first and then move on to your multiplication.

The two integers that surround the square root of 87 are 9 and 10.

The first step is to find out the square root of 87:

= √87

= 9.33

Integers are all whole numbers numbering from 1 to infinity so the two integers the square root will be between are the integers immediately below 9.33 and above it. These numbers are:

9 is immediately below 9.33

10 is immediately above 9.33

In conclusion, the square root of 87 is between 9 and 10.

Answer with explanation:

1.⇒Area of Parallelogram = Corresponding height × Base

                                        = 2 cm × 18 mm

→1 cm = 10 mm

So,  Area of Parallelogram

                                = 2 cm × 1.8 cm

                                 = 3.6 cm²

Option C: →3.6 cm²

→→→2. A triplet ,that is set of three numbers is called Pythagorean triplet, if it is of the form of : {m²-1, 2 m , m²+1}

That is if you write the Pythagorean rule for Right triangle, having sides , m²-1, 2 m , m²+1

then ,→ Square of Largest side = Sum of squares of two smallest side

Square of Largest Side = (m²+1)²

Sum of squares of two smallest side= (2 m)² + (m²-1)²

                  = 4 m² + (m²)² -2 m²+1

                 = (m²)² +2 m²+1

                  =(m²+1)²

So, we will check out , out of four options which of them are Pythagorean Triplet.

Option 1.

Square of Largest Number = 82²=6724

Sum of squares of two smaller number= 42² + 40²

                      = 1764 +1600

                     = 3364

→Square of Largest Number ≠Sum of squares of two smaller number

6724 ≠ 3364

Not a Pythagorean Triple.

Option 2.

Square of Largest Number = 58²=3364

Sum of squares of two smaller number= 42² + 40²

                      = 1764 +1600

                     = 3364

→Square of Largest Number =Sum of squares of two smaller number

3364= 3364

A Pythagorean Triple.

Option 3.

Square of Largest Number = 58²=3364

Sum of squares of two smaller number= 41² + 41²

                      = 1681 +1681

                     = 3362

→Square of Largest Number ≠Sum of squares of two smaller number

3364 ≠ 3362

Not a Pythagorean Triple.

Option 4.

Square of Largest Number = 57²=3249

Sum of squares of two smaller number= 41² + 40²

                      = 1681 +1600

Final answer:

To solve the addition of 4 yards 8 inches and 6 yards 6 inches, we add yards to yards and inches to inches, resulting in 10 yards 14 inches, which simplifies to 10 yards and 2 inches because 12 inches make a foot, and 3 feet make a yard.

Explanation:

The student's question involves adding two measurements together: 4 yards 8 inches and 6 yards 6 inches. In mathematics, especially in the measurement units topic, it is common to work with both the same and different units when performing calculations. To add these two measurements, we must add the yards together and the inches together separately. Since 1 yard equals 3 feet, this information can be used to convert yards to feet if necessary.

\n\n

First, add the yards: 4 yards + 6 yards = 10 yards. Next, add the inches: 8 inches + 6 inches = 14 inches. Because there are 12 inches in a foot, 14 inches is equivalent to 1 foot 2 inches. Thus, we need to convert this extra foot into yards, knowing that there are 3 feet in 1 yard, so 1 foot = 1/3 yard.

\n\n

We have 10 yards from the initial addition and an additional 1/3 yard from converting the extra foot to yards. Adding these together, we get 10 yards + 1/3 yard = 10 1/3 yards. Since there are no more than 12 inches in the remaining inches part, our final answer in yards and inches is 10 yards 2 inches.

The number 69 is 75 % or 75 percentage of the number 92

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage be represented as A

Let the first number be n₁ = 92

Let the second number be n₂ = 69

And , the percentage value of 69 of the number 92 is given by

n₂ = ( A / 100 ) x 92

On simplifying , we get

69 = ( A / 100 ) x 92

Multiply by 100 on both sides , we get

6900 = 92A

Divide by 92 on both sides , we get

A = 6900 / 92

A = 75 %

Therefore , the value of A is 75 %

Hence , the percentage value of 69 of the number 92 is 75 %
