Answer:
Step-by-step explanation:
the tangent of an angle is equal to the opposite side length over the adjacent side length
tan(P) = 3/5 = 0.6
Answer:
Step-by-step explanation:
1. multiply by 2
2. multiply by 4 -> 96
3. by 3 ->120
Answer: f(x) = ∛(x+4)^2=8 + 3 = 11
4x5=20-9=11

Answer:
6 7/12 hours in June
Step-by-step explanation:
Find the answer to this question by subtracting 6 4/6 hours from the total 13 1/4 hours:
13 1/4 hours is equivalent to 12 5/4 hours (we borrow '1' from 13 1/4).
Thus, we have
12 5/4 hours Note that the LCD of 5/4 and 4/6 is 12. Thus
- 6 4/6 hours we have
12 15/12 hours
- 6 8/12 hours

6 7/12 hours

Answer:94%
Step-by-step explanation:
Half life of a radioactive element is the time taken for half it's mass to disintegrate away.it means after attaining half life,what will be left is 100-50=50%.
Let the 100% mass of C-14,be x
Then 5730years=1/2 of X
Then 660 years=y of X
Where Y is the fraction of C-14 that has disintegrate as at 1988.
5730/660=1/2X/yX
5730/660=1/2/y
Cross multiplying
5730×y=660×1/2
5730y=330
Y=330/5730=0.05759
In %,5.76%
Amount of C-14 left is
100-5.76=94.24=94% as at 1988.
