Answer:
2/7
Step-by-step explanation:
-1 1/7 + 6/7 = -8/7 + 6/7 = 2/7
Answer:
First, make the double negative a positive.
So, (-6/13) + (7/15)
Then multiply the numerator, 6×7=42
And denominator 13×15=195
42/195 simplify by dividing both by 3 so 14/65
Do 252 divided by 36 and you should get 7. so the average number of calls would be 7
Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)
Evaluating using a calculator gives 20.92 units.
The answer to your question is 8.9
