Answer:
yes
Step-by-step explanation:
We have been given that a right △ABC is inscribed in circle k(O, r).
m∠C = 90°, AC = 18 cm, m∠B = 30°. We are asked to find the radius of the circle.
First of all, we will draw a diagram that represent the given scenario.
We can see from the attached file that AB is diameter of circle O and it a hypotenuse of triangle ABC.
We will use sine to find side AB.
Wee know that radius is half the diameter, so radius of given circle would be half of the 36 that is 
.
Therefore, the radius of given circle would be 18 cm.
Answer:
1/10
13/100
4/5
12/25
3/10
63/100
3/5
51/200
2/9
5/11
To prove the last 2 recurring ones:
0.222222... = x
10x = 10 * 0.22222... = 2.222222....
Notice how the decimal part of 10x is the same as for x:
10x - x = 2.2222222... - 0.222222... = 2
10x - x = 9x = 2
x = 2/9
Same procedure for the other one but times by 100 instead:
x = 0.454545...
100x = 45.454545...
100x - x = 45.454545... - 0.454545... = 45
100x - x = 99x = 45
x = 45/99 = 5/11
A. 4x-4
We want the expressions to be equal, and:
4(4x-4)= 16x-16
So, A is the answer
So the scale is usually ine inch of the map to actual distance right?we
So we need to calculate how much one inch is.
So we are told 10 inches is 1250 miles right?
So for one inch we need to divide the number of inches for the equivalent distance.
In this case it is 10 and 1250 miles.
So dividing 1250 by 10 gives you 125 right?
That means for every one inch on the map it is 125 miles right.
This can be written like 1:125.
This is how they write scales in the map.
It means for one unit in the map it is 125 units in real life
