A unit circle is the one which has radius equal to 1.
The relation between radius of circle (r), the arc length (s) and the radian measure of angle made by arc (Ф) is given as:
s = rФ
For a unit circle, r = 1, so the above equation becomes:
s= Ф
This means, the arc length will be equal to the angle made by that arc in radians.
Answer:
The correct answer is -
a. 4.5 inches.
b. side or arm (a)
c. (a) or 4.5, and 18
d. (d) 4.5, and 14.1428
e. 22/7 × r^2 = 15.90
Step-by-step explanation:
Given :
Radius or r = 2 ¼ inches
Solution:
a. the diameter of the circle -
d = 2r
= 2 ¼ *2
= 2.25*2
= 4.5
b. The diameter of the circle is the same length as one side or arm of the square which is
a = d = 4.5
c. The perimeter of the square
P = 4a = 4d = 4*4.5 = 18
d. Perimeter of the circle =
2πr = πd = (22/7)*4.5
= 14.1428
e. the area of the circle =
22/7 × r^2
= 15.90
So you have to divide the amount by how many you’re buying and get the unit rate per each ounce so the answer is b
Answer:
P(Hispanic or Bilingual) = 0.429.
Step-by-step explanation:
This question is solved treating these events as Venn probabilities.
I am going to say that:
Event A: Hispanic
Event B: Bilingual
Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:
This means that:
What is the probability that teacher is Hispanic or bilingual?
This is:
With the values that the exercise gives us:
So
P(Hispanic or Bilingual) = 0.429.
Which value of v makes 12=12+\defray{v-8}{2}12=12+ 2 v−8 12, equals, 12, plus, start fraction, v, minus, 8, divided by, 2, end

The value of 
which makes the statement true is 8.
<u><em>Explanation</em></u>
The given statement is: 
For finding the value of which makes the statement true, we will just solve the above equation for .
First we will <u>multiply both sides by 2</u> and then solve for . So.......
Thus, the value of which makes the statement true is 8.
