Studying for a test but I’m kinda confused here because it says the answer is 20cm but I’m getting it wrong every time so can someone explain why it’s 20cm
Answers
Answer:
Hope this helps. :)
Step-by-step explanation:
The circumference formula is 2 times pi times r, so 2 times 3.14, times your radius. In this question it wants us to leave the answer in terms of pi. So all you do is 2 times the radius which is just 2 times 10. If you still don't understand let me know and I can help explain it to you again using an example.
or pi times the diameter which is 20.. the correct answer is 20 times pi (3.14usually) or 60.28 com.

Equation 2 should represent a parabola that opens down and has a negative y- intercept.
Answers
Answer
The general equation of a parabola is \(y^2=4ax\) which represents parabola opening along the positive x-axis and vertex at the origin.
Second equation of the parabola is \(y^2 = -4ax\) which represents parabola opening in negative x-axis and vertex at origin.
3rd Equation of parabola is \(x^2 = 4ay\) which represents parabola opening along the positive y-axis and vertex at the origin.
4th equation of the parabola is \(x^2 =- 4ay\) which represents parabola opening along negative y-axis and vertex at the origin.
Hence, the 4th equation represents Equation 2 which is \(x^2 =- 4ay\), and parabola opens down and has a negative y-intercept.

Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to

Answer:
B) 60%
Step-by-step explanation:
Percentage formula
\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)
Therefore, 120 is 60% of 200.

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.
Hope this helps!

A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

QUICK! Find the area of the smallest square in the diagram.
A) 25 square feet
B) 5 square feet
C) 313 square feet
D) 13 square feet
Answers
Answer:
313 square feet
Step-by-step explanation:
313 square feet
Answer:
A) 25
Step-by-step explanation:
sides of top square are all 13 and sides of bottom square are all 12
we now have the hypotenuse (13) and another side length of the triangle (12) using a^2+b^2=c^2 we can find the side of the square then its area.
144+b^2=169
b^2=25
b=5, which means the smallest square's sides are all 5 making it have an area of 25
