how do squaring and taking the square root relate
Answer:
Finding the square root of a number is the inverse operation of squaring that number.
Remember, the square of a number is that number times itself.
The perfect squares are the squares of the whole numbers.

What is the area of a circle with a diameter of 16 centimeters?
A. 50.24
B. 100.48
C. 200.96
D. 803.84
Answer:
A≈201.06
Step-by-step explanation:
so it would be about 200.96
Answer:
C. 200.96
Step-by-step explanation:
First, find the radius by dividing 16 by 2:
16/2
= 8
Use the area formula to find the area:
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](8)²
A = 64[tex]\pi[/tex]
A = 201.06
This answer is closest to C, 200.96
So, the correct answer is C. 200.96

What is the relashionship between the sides in a right triangle
Angle 1 and Angle 2 are complementary angles. The measure of angle 1 is 42 degrees. The measure of angle 2 is 3x degrees. Find the value of x.
Answer:
x=16
Step-by-step explanation:
complementary means 90 degrees so
42 +3x = 90
3x=48
x=16
Question 6 of 10
A triangle has sides measuring 8 inches and 12 inches. If x represents the
length in inches of the third side, which inequality gives the range of possible
values for X?
A. 8< x < 12
B. 4 < x < 20
C. 4 sxs 20
D. 8 sxs 12
SUBMIT
Answer:
the answer is b
Step-by-step explanation:
The possible inequality for x is 4 < x < 20.
The correct option is (B).
What is inequality?Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides.
We are given that,
A triangle has sides measuring 8 inches and 12 inches. If x represents the length in inches of the third side
8+12=20
so it has to be less than 20, and 12-8=4,
So it has to be more than 4,
So the only answer that makes sense is
4<x<20.
Therefore, option B is correct.

Which equation has the greatest rate of change?
y=12x-7
y=5x+9
y=4x+12
y=X+36
Answer:
y=12x-7
Step-by-step explanation:
Rate of change is the same thing as slope which can be found by looking at the value before the x. Since 12 is the largest number, it has the largest rate of change.

The radius of a circle is 3 m. Find its circumference in terms of pi
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!
(btw if pi is something else, use these steps to help you out)
The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.

What is the relationship between rigid motions and congruence?
Answer:
Rigid Motion and Congruence Two figures are congruent if and only if there exists one, or more, rigid motions which will map one figure onto the other. (thus maintaining the conditions for the figures to be congruent).
Step-by-step explanation:
Two figures are congruent if and only if one or more rigid movements can map one figure onto the other, according to the link between rigid motion and congruence.
Rigid motions and congruence are closely related concepts in geometry.
Rigid motions are transformations that preserve the shape and size of a geometric figure.
They include translations, rotations, and reflections.
Congruence, on the other hand, refers to the relationship between two geometric figures that have the same shape and size.
When two figures are congruent, it means that they can be transformed into each other using a combination of translations, rotations, and reflections, which are all types of rigid motions.
In other words, if two figures are congruent, it implies that there exists a sequence of rigid motions that can be applied to one figure to transform it into the other figure.
Conversely, if two figures can be transformed into each other through rigid motions, then they are congruent.
The key idea is that rigid motions preserve the length of segments, the measure of angles, and the overall shape of figures.
By using rigid motions, we can establish congruence between geometric figures.
This concept is fundamental in geometry as it allows us to compare and analyze shapes and their properties.

b) ✓159 is not a whole number
Hey there!
The answer to your question is B.) √156
Whole numbers are numbers greater than 0 that, when changed to a fraction in its simplest form, the denominator would be 1.
The square root of a number is a whole number that, when multiplied by itself, equals the original number. Example: √4 = 2, because 2 x 2 = 4
So, we will find the square root of each of the following:
√144 = 12
√156 = 12.489996...
√169 = 13
√196 = 14
Therefore, √156 is not a whole number, because it cannot be simplified into a fraction over 1.

Answer this question to get 20 points!!!!
Answer:
Blue
Step-by-step explanation:
First, we need to find the LCD (Least common denominator)
Rewriting input as fractions if necessary:
1/10, 1/4, 1/5
For the denominators (10, 4, 5) the least common multiple (LCM) is 20.
Therefore, the least common denominator (LCD) is 20.
Now, we convert:
Red Marbles: 1/10 = 2/20
Blue Marbles: 1/4 = 5/20
Yellow Marbles: 1/5 = 4/20
As we can see, blue has the most. Now we have our answer! Good luck!

What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
On a coordinate plane, a curved line crosses the x-axis at (–1, 0), and crosses the y-axis at (0, –3).
If the graph of the function crosses the x-axis, then the intercept is known as the x-intercept. When the graph of the function crosses the y-axis, then the intercept is known as the y-intercept.
Then the intercepts of the graphed function will be x-intercept = (–1, 0) and y-intercept = (0, –3). Then the correct option is D.
