Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
B 216 because if you multiply pi with the answer you get 678.58
Answer:
the value of f is 13
Step-by-step explanation:
this is the answer of thia question
The figure is right triangle with base =segment AB = 3 and height = segment AC = 2.
The angle B has tangent, tan (B) = 2 / 3
The angle C, has tangent, tan (C) = 3 / 2
Then, the answer is option C, tan C
You add 2 to 8 to get 10. I decided on that because that's just what you do for simple addition. ;)
