Points A, B, and C lie on a line.
Point A is between points B and C.
Starting at point A and going past point B, you have ray AB.
Starting at point A and going past point C, you have ray AC.
If you think of angle BAC, it is a straight angle of 180 degrees.
You have the two rays AB and AC forming a line and an angle.
Answer:
Formula for the area of a circle;
A = π
Where 'π' represents pi(22/7 or 3.14), and 'r' stands for the radius being squared.
But, we are given a <u>diameter</u> instead of a <u>radius</u>.
So to find the radius of the diameter we must find 1/2(half) of the diameter:
Diameter/2 = Radius
Plug in what we know:
D/2 = R
8/2 = R
4 = R, <u>4 is our radius</u>.
Now we use this radius in our formula;
A = π
A = 3.14(4^2) ← (The symbol ' ^ ' means to the power of.)
A = 3.14(16)
A = <u>50.24 centimetres</u> is the area for this circle.
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
X = 34
<span>2+8-x=-24
</span>Add 2 + 8: 10-x=-24
Subtract 10 from each side: -x = -34
Change the signs from each side: x = 34
Answer: The director can choose two singers from the 20 singers in 190 different ways.
Step-by-step explanation:
Given : The total number pf singers auditioning for the musical= 20
The number of singers looking director for = 2
We use combinations here because order of selecting singers does not matter.
(If order matters then we use permutations.)
The number of combinations of to select r things of n things =
So the number of ways can the director choose two singers from the 20 singers=
Therefore , the director can choose two singers from the 20 singers in 190 different ways.
