What is the formula to find the side?
The formula to find the side of a geometric shape depends on the shape itself. Few details like area or perimeter of a shape or surface area or volume of a solid with few other parameters should be known.
Few examples :
For a square, the formula to find the side (s) is:
s = √(A)
where A is the area of the square.
For a rectangle, the formula to find the length (l) and width (w) are:
l = A/w and w = A/l
where A is the area of the rectangle.
For a triangle, the formula to find the base (b) and height (h) are:
A = (b*h)/2
where A is the area of the triangle.
For a cube, the formula to find the side (s) is:
V = s^3
where V is the volume of the cube.
Keep in mind that these are a few examples of formulas that can be used to find the side of a geometric shape. Depending on the specific problem, different formulas may be required.

What is a Square Number?When an integer is multiplied by the same integer, the resultant number is known as a square number. Simply put, a square number is a number that is obtained by the product of two same numbers but in this case, it is an equation, so the equation in the bracket multiplies itself.
Properties of Square NumbersSquare numbers always end with the digits 0, 1, 4, 5, 6, and 9. The number of zeros at the end of a square number is always even. This means if a number has an odd number of zeros at the end, then the number is not a square number. The square of even numbers is always even, and the square of odd numbers is always odd(x – 7)² = 36
Raising both sides by 1/2
x-7 = √36
x - 7 = 6
x = 6+7
x = 13

Jeanette took two tests. Find her z-score for each test. (Remember: The number of standard deviations between a score and the mean score is indicated by a z-score.) On which did she score better compared with others in her class
The z-score is compared as Test A : 3.25; Test B : 3.5; Test B.
What is the z-score to be compared?The Z-score is a statistical measure that describes the relationship of a value to the mean of a group of values. The Z-score is expressed in standard deviations from the mean. A Z-score of 0 indicates that the data point's score is the same as the mean score.Here given that,
Test A
Jeanette's score 90
Mean score 64
Standard deviation 8
Test B
Jeanette's score 95
Mean score 60
Standard deviation 10
The formula =
z = x - µ / σ
By substituting,
test A : z = (90 - 64) / 8 = 26 / 8 = 3.25
test B : z = (95 - 60) / 10 = 35/10 = 3.5
So Test A : 3.25; Test B : 3.5; Test B

Z-score in test A = 3.25, Z-score in test B = 3.5. She performed better in test B.
What is Z-score?Z-score represent the difference between a given value and standard deviation.
What is the Z-score of the above question?given, Jeanette scored 90 in the Test A
mean score of test A = 64
standard deviation = 8
we know, the Z-score is calculated by the following formula.
Z-score = (X - μ) /σ
where, σ denotes the standard deviation.
μ denotes the mean value
X is the actual value
Test A has Z- score = (actual score - mean score) / standard deviation
= (90 -64)/8
Z = 3.25
In the test B, she scored 95.
actual score = X = 95
mean score in test B = 60
standard deviation in test B = 10
hence, Z-score for test B = (X - μ)/ σ
= (95 -60)/ 10
Z-score = 3.5
Therefore, Jeanette scored better in her test B.

Answer:
[tex]108\pi[/tex] or approx. [tex]339.3 m^{2}[/tex]
Step-by-step explanation:
The question asks us to find the total surface area of the given hemisphere. The question gave us the formula for total surface area of a sphere, [tex]SA_{tot} =4\pi r^2[/tex]. But we need it for a hemisphere, so multiply the equation by [tex]\frac{1}{2}[/tex].
[tex]SA} = (\frac{1}{2}) 4\pi r^2[/tex] => [tex]SA} =2\pi r^{2}[/tex]
We also need the area of the base, which is circle. [tex]A_{circle}=\pi r^{2}[/tex].
Now add these equations together to get our equation.
[tex]SA_{tot} =2\pi r^2 +\pi r^{2}[/tex] => [tex]SA_{tot} =3\pi r^2[/tex]
Now we have the proper equation for total surface area of a hemisphere, [tex]SA_{tot} =3\pi r^{2}[/tex]. Plug in the value of [tex]r[/tex] which is given in the problem, [tex]r=6m[/tex].
=> [tex]SA_{tot} =3\pi (6)^{2}[/tex] => [tex]SA_{tot} =3\pi (36)[/tex] => [tex]SA_{tot} =108\pi m^{2}[/tex] or approx. [tex]339.3 m^{2}[/tex]
[tex]\sqrt{18}+\sqrt{50}[/tex]
[tex]3\sqrt{2} +5\sqrt2}\\=8\sqrt{2}[/tex]
Answer:
8√2
Step-by-step explanation:
Both 18 and 50 are easily factorable, the first as 2*9 and the second as 2*25. Taking the square root of 18 results in 3√2 and that of 50 in 5√2/
Thus, the original problem √18 + √50 simplifies to (3 + 5)√2, or 8√2

What is the radius of circle M?
Answer:
The radius is just under 4 cm.
Step-by-step explanation:
The central angle for the entire circle is 360 degrees.
The fraction (89/360)(total circle area) = 12.36m^2.
Solving for the total circle area, we get (360/89)(12.36m^2) = 50 cm^2.
Area of a circle (in general) is A = πr²
Here we know A and π and must find r² and then r:
A
A = πr² becomes r² = ----------

Here, r² = 50 cm^2 / 3.14 = 15.92 cm^2
and r = square root of r² = 3.99, or approximately 4 cm

The perimeter of a rectangle is 84 feet long. The
length is six more than two times its width. What are
the dimensions of the rectangle? (Hint: P = 2L + 2W)
Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4
Establish a perimeter.The perimeter, or total length, of a shape is referred to as its perimeter in geometry. A shape's perimeter is calculated by summing the lengths of all of its sides and edges. By adding together the lengths of all a shape's sides, one may determine its perimeter. The circumference of a field, for instance, will be 78 yards for a rectangle with dimensions of 24 yards long by 15 yards wide.
Here,
Given :
Perimeter of rectangle = 84 feet
Thus,
Length is 6 times more than its 2 time width
=> 6L = 2W
=> W = 3L
In the perimeter formula:
=> 3L + 2L =84
=> 5L = 84
=>L = 84/5
=>16.8
and
W = 3L
=> W = 3*16.8
=> W = 50.4
Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4

An equation is shown. What values of x makes the equation true?
5x + 3x = 5x + 15/2
Step-by-step explanation:
1) Add 5x and 3x.
Now you have 8x = 5x + 15/2
2) Subtract 5x from the right side of the equation.
(You also do this to the left side)
Now you have 3x = 15/2
3) Now we want the value of x not 2 or 3x, so we will need to divide 3x by 3 to get the value of x.
3x/3 = 15/2 /2 (If the fraction divided by 3 looks confusing you can convert it into a decimal)
So you would have 3x/3 = 7.5/2
3x/3 = x
7.5/3 = 2.5
x = 2.5Hope this helps !

In the figure where 3x20 and 4x-36, which value of x will make aob, a traight line
The value of x that will make aob a straight line equation is x = -6.
To make aob a straight line, we need to make the gradients of both lines equal.
The gradient of the first line is 3x20 = 60.
The gradient of the second line is 4x-36 = 4x-36.
To make the gradients equal, we need to solve the equation 4x - 36 = 60.
Subtracting 36 from both sides gives us: 4x = 96.
Dividing both sides by 4 gives us x = -6.
Therefore, the value of x that will make aob a straight line is x = -6

So, ∠O = ∠N
And, Measure of ∠P = 50°
Now,
In the ΔNOP;
The sum of all the three angles are 180°.
The value of the measure of ∠O = x
We get;
∠O + ∠N + ∠P = 180°
Substitute ∠P = 50° and ∠O = ∠N = x we get;
x + x + 50 = 180
2x + 50 = 180
2x = 180 - 50
