Answer:
r = 21 cm
Step-by-step explanation:
The radius of a circle is 1/2 of the diameter
r = 1/2d
r = 1/2(42)
r = 21 cm
Each of the angles in a triangle are 60 degrees, so when you add them together, you get 180
60+60+60=180
First you would have to isolate y.
3x - 3y = 18 -----> Subtract 3x from both sides
-3y = -3x + 18 --------> Now divide both sides by -3
y= x - 6
Now you replace the y with an f(x)
f(x) = x - 6
The answer is
2/5 = 0.4
Because
2/5 2 divide 5 = 0.4
ITS B. The range is the stuff in the right circle. So its 245
