Which step is the same when constructing an inscribed square and an inscribed regular hexagon?
O Construct a circle first
O Construct a line first
O Set the compass to the radus
Set the compass to greater than half the diameter
Question 4 Multiple Choice Worth 1 points)
(01.03 MC)
Answers
After the construction of a circle, we have to "Set the compass to the radius of the circle" so, option C is correct.
What is a regular hexagon?A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles. The sum of the measure of angles of a regular hexagon is 120 degrees.
Steps to create an inscribed hexagon:
1: The structure needs to adjust the box thickness towards that radius.
2: Afterward moves around the outside of the circular path to just produce the 6 vertices of that similar hexagon.
"Set the compass to the radius of the circle" so, option C is correct.
Thus the above answer is correct.

Answer:
Construct a circle first
Step-by-step explanation:
If you're going to inscribe any figure in a circle, the first construction you need to do is construct the circle.

Additional comment
The attached shows our construction of an inscribed square and an inscribed regular hexagon. Here are the steps we used. You will notice the first step is construct a circle. (It could be, construct line AB, then construct circle A with radius AB.)
We have used line AB in the construction of the hexagon, but the hexagon could have been constructed without it. That is why "construct a circle first" is likely a better choice for a common first step.

Label intersection points K and L.using C as a center, draw arc JM. Label intersection points J and M.draw inscribed hexagon CJKBLM__
Arguably, the first step to constructing a circle is set the compass to the radius. We chose to ignore this because one of the ways to construct an inscribed hexagon is to mark off successive arcs around a circle that have a radius equal to the radius of the circle. We did not use that method. (The use of diameter BC made drawing 5 arcs around the circle unnecessary. We drew 2 instead.)
Or, you could argue that construct a line first is needed before you set the compass to the radius. If this is the first step, then the next steps would be to mark the center of the circle on the line, and mark another point at a distance of the radius from that center point.
What you consider to be the first step depends on the level of detail you want to attend to.

Grades 3, 4, and 5 have their annual field day together. Each grade is given 15 gallons of water. If there are a total of 370 students, will there be enough water for each student to have 2 cups? First, solve for how many cups the students have.
Answers
Using proportions, it is found that the number of cups per student is of 1.97. hence there will not be enough for each student to have 2 cups.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Each gallon is worth 16 cups, hence, since each grade is given 15 gallons of water, and the trip consists of three grades, the number of cups is given by:
C = 3 x 15 x 16 = 720.
There is a total of 370 students, hence the number of cups per student is given by:
n = 720/370 = 1.97.

Answers
Answer:
25
Step-by-step explanation:
When multiplying a whole number by a fraction, the first step is to multiply the whole number by the numerator. Then, you divide by the denominator. For example, on the left side, 5 x 5 = 25. You are left with 25/6. Finally, when you divide by 6, you are left with 4.166.....
If the denominator is the same (6) on both sides, to get the same answer, you somehow need to get the numerator (25) the same. So, what whole number can be multiplied by 1 to get 25? This number is 25. Therefore, the missing number is 25. This answer is correct because 25 x 1 = 25. You would be left with 25/6 and get a final answer of 4.166....

The graph will reflect across the y-axis and then shift units to right.
Answers
The transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.
How to determine the transformation?The missing phrase in the question is: "If f(x) = 2ˣ + 1 is modified as g(x) = 2⁻ˣ + 1 - 5"
The functions are given as:
f(x) = 2ˣ + 1
g(x) = 2⁻ˣ + 1 - 5
First, the function f(x) is reflected across the y-axis (this eliminates options a and c)
The rule of this transformation is
(x,y) ⇒ (-x,y)
So, we have:
f'(x) = 2⁻ˣ + 1
Next, the function f(x) is shifted down by 5 units (this eliminates options d)
The rule of this transformation is
(x,y) ⇒ (x,y - 5)
So, we have:
f''(x) = 2⁻ˣ + 1 - 5
By comparing the functions f"(x) and g(x), we have:
g(x) = f''(x) = 2⁻ˣ + 1 - 5
Hence, the transformation is (b) The graph will reflect across the y-axis and then shift 5 units down.

The statement that is true for ΔXYZ and ΔX''Y''Z'' is; 2: ΔXYZ and ΔX''Y''Z'' are congruent
How to identify coordinates of transformed triangles?We are told that;
- Triangle XYZ is rotated 90º clockwise about the origin to form triangle X'Y'Z'.
- Thereafter, reflected across the x-axis to form triangle X''Y''Z''
Now, in transformation, Reflection is flipping an object across a line without changing its size or shape while Rotation is rotating an object about a fixed point without changing its size or shape. Thus, it means that the size and shape of the triangle formed is not different from the original one.
Thus, we can say that both triangles are congruent because the shape and size didn't change.
