Step-by-step explanation:
This for num 2
[tex] \sqrt{8} = \sqrt{2 \times 4} = 2 \sqrt{4} = 2[/tex]
6÷2=3
1.
To solve [tex]\sqrt[n]{16}=2[/tex], you need to turn the question around and ask what value of n makes [tex]2^n=16[/tex].
n = 4
2.
To simplify this, your teacher could mean two things, either "just simplify the radical" or "rationalize the denominator."
For the first option, [tex]\sqrt{8}=\sqrt{4\cdot2}=\sqrt{4}\cdot\sqrt{2}=2\cdot\sqrt{2}[/tex], so your overall expression becomes:
[tex]\dfrac{6}{2\cdot\sqrt{2}} = \dfrac{3}{\sqrt{2}}[/tex]
Now if your teacher also wants the denominator rationalized, then you keep going and multiply that by [tex]\dfrac{\sqrt{2}}{\sqrt{2}}[/tex]:
[tex]\dfrac{3}{\sqrt{2}}\cdot \dfrac{\sqrt{2}}{\sqrt{2}}=\dfrac{3\sqrt{2}}{2}[/tex]

Kendrick i packing crate that can hold 8 pear, and Nick i packing crate that hold 4 pear. If they mut pack the ame total number of pear, what i the minimum number of pear each mut pack?
Answers
The minimum number of pears that each must pack is x = 12 pears.
We can start by using algebra to represent the problem.
Let x be the number of pears that Kendrick and Nick must pack.
We know that the total number of pear that Kendrick packs is 8 pear per crate * the number of crates he packs = 8x. Similarly, the total number of pears that Nick packs is 4 pears per crate * the number of crates he packs = 4x.
Therefore, the total number of pears that Kendrick and Nick must pack is 8x + 4x = 12x. We are given that they must pack the same total number of pears, so we can set this equal to x. Therefore, we have:
12x = x
So the minimum number of pears that each must pack is x = 12 pears. This means that Kendrick must pack 12 pears in 8 crates and Nick must pack 12 pears in 4 crates.
It could be also represented as:
Kendrick: 8 pear/crate * C crates = 12 pear
Nick: 4 pear/crate * C crates = 12 pear

Using the conversion 8km/h = 5mph convert 28m/s to mph.
If your answer is a decimal, give it to 1d.p
Answers
Miles per hour and meters per second are formally known as mph and m/s, respectively.
Kilometers per hour 28 km/h
Miles per hour 62.6342
What is mph to m/s Formula?Let's first review the metric conversions for a mile and an hour. Speed is the distance traveled in a given amount of time.
Miles per hour and meters per second are formally known as mph and m/s, respectively. If so, converting mph to m/s will be simple. We are cognizant of:
A mile is equal to 1.60934 kilometers or 1609.34 meters.
3600 seconds make up 1 hour, which is equal to 60 minutes, 60 minutes, and 60 seconds.
With the help of these conversions, let's create the mph to m/s formula.
mph to m/s Formula
1 mph = 1 mile per hour
=1 mile / 1 hour
=1609.34 meters/3600 seconds
0.447 meter / seconds
=0.447 m/s
So, multiplying by 0.447 is required to change mph to m/s.

Answers
The hip breadth of 95% of all male is 16.2 inches, which is greater than the mean of 14.8 inches with a standard deviation of 0.9 inches.
1. Calculate the Z-score for 95th percentile:
Z = (P95 - mean)/standard deviation
= (16.2 - 14.8)/0.9
= 2.44
2. Look up the Z-score in a Z-table to find the corresponding percentile:
95th percentile = 2.44
The hip breadth of 95% of all male can be calculated using the normal distribution. First, we must find the Z-score for the 95th percentile, which is calculated by subtracting the mean (14.8 inches) from the desired percentile (16.2 inches) and dividing by the standard deviation (0.9 inches). This gives us a Z-score of 2.44. We can then look this up in a Z-table to find the corresponding percentile, which is 95th percentile. Therefore, the hip breadth of 95% of all male is 16.2 inches.

A circular plate has circumference 28.3 inches. What is the area of this plate? Use 3.14 for π.
Answers
The round plate in the problem has a surface area of 63.754 square inches.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, A circular plate has a circumference of 28.3 inches.
Since circumference of a circle = 2*3.14 * r
Where r is the radius
Thus,
circumference = 28.3
6.28 * r = 28.3
r = 4.506
Radius of circle = 4.506
Since the area of the circle = 3.14 * r * r
Thus,
Area of given circle = 3.14 * 4.506 * 4.506
Therefore, the Area of the given Circular plate is 63.754 square inches.

Answers
To find the radius of the circular area, the organizers must divide 50,000 by pi and then multiply by 5. The result of this calculation is the amount of area needed, which can then be divided by pi to find the radius of the circular region, rounding to the nearest foot.
To find the radius of the circular area, the organizers should first calculate the amount of area needed to accommodate each person in the field. This is done by dividing the total number of people (50,000) by pi and then multiplying by 5, which represents the 5 square feet of space allotted to each person. The result of this calculation is the amount of area needed to fit all 50,000 people. Next, the organizers should divide this area by pi to calculate the radius of the circular region. Finally, they should round the result to the nearest foot. This will give them the radius of the circular area that is needed to fit all 50,000 people in the field.

Answers
Step-by-step explanation:
(f○g)(x) = f(g(x))
it simply means that we put the expression of g(x) into ask places of x in f(x).
(f○g)(x) = g(x)² + 3
therefore,
g(x)² + 3 = 9x² - 12x + 7
g(x)² = 9x² - 12x + 4 = (a + b)² = a² + 2ab + b²
9x² = a² tells us that a = ±3x
4 = b² tells us that b = ±2
which signs of a and b do we need ?
-12x = 2ab gives us the answer
-6x = ab
that means the signs need to be opposite and we have 2 possible solutions

What are fractions?In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, while the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.
Let us suppose the total number of problems assigned = x.
Given that the problems solved on Saturday is 3/5 of her total questions. This is represented as:
(3/5) x
The remaining problems are:
1 - (3/5) x = (2/5) x
On, Sunday the problems solved are 1/3 of the remaining. This is represented as:

(2/15) x
The remaining problems are:
(1 - 1/3)(2/5 x) = (2/3) * (2/5) x = 4/15 x
Given that the final number of problems remaining are 4, that is:

What is type of solution Class 9?.
Answers
The types of solutions for an equation depend on the type of equation, but in general, the most common types of solutions are: single solution, no solution and infinite solutions.
In mathematics, particularly in algebra, a solution of an equation is a value or a set of values that, when substituted into the equation, makes it a true statement.
Single solution: An equation has a single solution when it has exactly one value that satisfies the equation. This solution is unique and it can be found by solving the equation for the variable.
No solution: An equation has no solution when it is impossible to find a value that satisfies the equation. This happens when the equation is contradictory or inconsistent. For example, the equation "2x = 5x + 1" has no solution because no value of x can make the equation true.
Infinite solutions: An equation has infinite solutions when any value of the variable satisfies the equation. This happens when the equation is an identity, meaning it is true for all values of the variable. For example, the equation "2x + 0 = 2x" has infinite solutions because any value of x will make the equation true.

The absolute value of the difference between 4x and 2 is less than or equal to 2
Answers
The inequality form of the statement is: |4x - 2| ≤ 2. And the lowest value of x that makes this inequality true is x = -1.
To solve for the lowest value of x that makes this inequality true, we need to consider two cases:
If 4x - 2 ≥ 0, then |4x - 2| = 4x - 2, so the equation becomes:
4x - 2 ≤ 2
Adding 2 to both sides, we get:
4x ≤ 4
Dividing both sides by 4, we get:
x ≤ 1
If 4x - 2 < 0, then |4x - 2| = -(4x - 2), so the equation becomes:
-(4x - 2) ≤ 2
Adding 2 to both sides, we get:
-4x + 4 ≤ 4
Dividing both sides by -4, we get:
x ≥ -1
So, the solution to the inequality is -1 ≤ x ≤ 1. This means that any value of x that lies between -1 and 1, inclusive, satisfies the inequality.
So, the lowest value of x that makes this inequality true is x = -1.
