Answer:
138
Step-by-step explanation:
70 + 32 = 102
102 + 36 = 138
138 + 40 = 178
178 + 44 = 222
Answer:
B
Step-by-step explanation:
Put "Volume of a Cone" in your browser and all you have to do is type the height and radius.
What are you trying to ask? Do you need the notation for this? If so, the notation is:
(-∞,-3)
or
n∠-3
What this is asking is for you to plug values into the following function:

Since the question is asking you to find

, this is how you work it out:
You take the function;

And plug the numbers indicated in for x;

So the answer to f(3) - f(1) =
Answer:
B. 70°
Step-by-step explanation:
If this is an equilateral triangle, then each angle is 180/3 = 60
<A = 60 = x+3x+2x
60 = 6x
60/6 = 6x/6
10 =x
Angle B will also equal 60 degrees
BDA + x + B = 180
BDA + 10 + 60 = 180
BDA + 70 = 180
BDA = 180-70
BDA = 110
BDA and y are complementary angles since they form a straight line
BDA + y = 180
110 +y =1 80
y = 180-110
y = 70
