Final answer:
The length of the diagonal in a square with side length s is s√2, calculated by using the Pythagorean theorem which relates the side lengths of a right triangle.
Explanation:
To find the length of a diagonal in a square with side length s, we can use the Pythagorean theorem. In a square, the diagonal splits the square into two right triangles. Therefore, the length of the diagonal can be seen as the hypotenuse of a right triangle where the other two sides are both of length s. The Pythagorean theorem tells us that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b).
Here is the step-by-step solution using the Pythagorean theorem:
Let the side length of the square be s.
Since the sides of the square are equal, the lengths of the two sides of the right triangle (formed by the diagonal) are also s.
According to the Pythagorean theorem, the square of the diagonal length d is d² = s² + s².
This simplifies to d² = 2s².
Take the square root of both sides to find the length of the diagonal d = √(2s²).
Therefore, the length of the diagonal is d = s√2.

The line plot shows what fraction of a mile 13 students ran during their fitness test. What is the sum of the shortest distance a student ran and the longest distance a student ran?
The sum of the shortest distance a student ran and the longest distance a student ran is 11/8
What is a fraction?A fraction represents equal parts of a whole, by dividing it up into equal partitions. Each fraction has a numerator and denominator. The denominator represents the total number of parts the whole has been divided into.
Given is a line plot, describing the distances that is a fraction of a mile, 13 students ran during their fitness test, we need to find the sum of the shortest distance a student ran and the longest distance a student ran,
Here, according to the graph, the shortest distance = 3/8 of a mile
And the longest distance = 8/8 of a mile
So, the sum = 8/8 + 3/8 = 11/8
Hence, the sum of the shortest distance a student ran and the longest distance a student ran is 11/8

What is a simplified Fraction?Simplest form conversion of incorrect fractions to mixed numbers. By reducing to the simplest words and outlining the effort required, this calculator also makes correct fractions simpler. A number that will divide equally into the numerator and denominator so that it may be lowered is required in order to simplify a fraction. To transform a fraction into a mixed number, the numerator must be higher than the denominator (an improper fraction).
Given, Paul has a piece of wood that is 4 yards long. He knows there are 12 inches in 1 foot, and 3 feet in 1 yard. total woods in inches would be,
total inches of wood = 4 yards
total inches of wood = 4 * 3 feet
total inches of wood = 4 * 3* 12 inches

What is the surface area of a triangular prism with dimensions of 10m, 9m, 6m, and 8m?
The surface area of the triangular prism with dimensions of 10m, 9m, 6m, and 8m is 218m².
Explanation:To find the surface area of a triangular prism, we need to find the sum of the areas of all its faces.
A triangular prism has two triangular bases and three rectangular lateral faces. Let's calculate the surface area:
1. The area of each triangular base can be found using the formula: 1/2 × base × height.
For the first base, the base is 10m and the height is 6m. So the area of the first base is 1/2 × 10m × 6m = 30m².
Similarly, for the second base, the base is 9m and the height is 8m.
So the area of the second base is 1/2 × 9m × 8m = 36m².
2. The area of each rectangular lateral face can be found using the formula: length × width.
The lengths of the lateral faces are 10m, 9m, and 6m.
The common width of the lateral faces is the height of the prism, which is 8m.
So the total area of the lateral faces is 10m × 8m + 9m × 8m + 6m × 8m = 152m².
3. Finally, the total surface area of the triangular prism is the sum of the areas of the bases and the lateral faces: 30m² + 36m² + 152m² = 218m².
Therefore the surface area of a triangular prism is 218m².

Which expression can be simplified by applying the additive inverse property
We have to identify the expression in which Additive inverse identity is applied.
Additive inverse property states that "The additive inverse of a number 'x' is a number that when it is added to 'x', yields zero".
Consider the first expression,
A. [tex] -329-164+513+206+(-164) [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
B. [tex] 1.6+0.2-1.8-0.5 [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
C. [tex] -\frac{7}{10}-\frac{3}{4}+1\frac{1}{2}+(-\frac{7}{10}) [/tex]
There are no such numbers, which will yield zero on addition. Hence, additive inverse property is not applied here.
D. [tex] 9\frac{3}{4}\+4\frac{5}{8}+(-9\frac{3}{4}+(2\frac{3}{5}) [/tex]
Here, [tex] 9\frac{3}{4} [/tex] when added to [tex] -9\frac{3}{4} [/tex] will yield zero. Therefore, [tex] -9\frac{3}{4} [/tex] is the additive inverse of [tex] 9\frac{3}{4} [/tex].
So, in option D, Additive inverse property is applied.

Sophie bikes at a speed of s miles per hour. Her friend Rana is slower, her biking speed is only r miles per hour.
Today the girls went for a 20 miles trip, each girl was biking at her usual speed. How long did Sophie wait for Rana after her own arrival to the finish?
Answer:
She waited for 20/r-20/s at the end of the line.
Step-by-step explanation:
The solution is, Time Sophie waits for Rana to arrive at finish point
=20/s - 20/r.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
here, we have,
The speed of Sophie and Rana are given as s miles per hour and r miles per hour.
The distance traveled by Sophie and Rand are 20 miles each.
The time taken by Sophie and Rana to travel 20 miles can be calculated by the formula
Speed =distance/time
Or, Time =distance/speed
Time taken by Sophie to travel 20 miles =20/s
Time taken by Rana to travel 20 miles =20/r
Time Sophie waits for Rana to arrive at finish point =20/s - 20/r

Which expressions are equal to 6^3 4^1/4^3 HELP ME ASAP PLEASE
We will be using division property of exponents.
The property is as follows:
[tex] \frac{x^{a}}{x^{b}} =x^{a-b} [/tex]
This means if we have same base in both numerator and denominator, the exponents will get subtracted.
In our question we have
[tex] \frac{4^{1}}{4^{3} } =4^{1-3} [/tex]
[tex] \frac{4^{1}}{4^{3} } =4^{-2} [/tex]
Now we will use another property of exponents here:
[tex] x^{-a} =\frac{1}{x^{a} } [/tex]
So if we take reciprocal of the above expression we will get,
[tex] 4^{-2} =\frac{1}{4^{2} } [/tex]
Rewriting the final answer:
[tex] \frac{6^{3} }{4^{2} } [/tex]

What is unique about Pythagorean triples? A The squares of the three sides add up to 100. B The length of each side is a perfect square. C The length of each side is a whole number. D The squares of the three sides are multiples of 3.
Final answer:
Pythagorean triples are sets of three whole numbers that form the sides of a right triangle and satisfy the Pythagorean theorem, a² + b² = c².
Explanation:
Pythagorean triples are unique because they consist of three whole numbers that satisfy the Pythagorean theorem.
Specifically, the squares of the two shorter sides (a and b), when added together, equal the square of the longest side (the hypotenuse, c). That is, a² + b² = c² holds true for these numbers.
Answering the student's question, the characteristic that is unique about Pythagorean triples is: C) The length of each side is a whole number.
This means that all three sides of the right triangle are integers, which is helpful in various mathematical and practical applications. Examples of Pythagorean triples include (3, 4, 5) and (5, 12, 13).
