-120° = -2π/3 radians.
Tangent is defined as Opposite/Adjacent or Sine/Cosine in a unit circle. So, if you have memorized the unit circle,
sin(-2π/3) = √3/2
cos(-2π/3) = -1/2
So, tan(-2π/3) would be:
Simplify, and you get:
And, so, tan(-2π/3) = -√3
Answer:
75 pounds
Step-by-step explanation:
To solve this problem, find 3/4 of 100.
To multiply fractions, multiply the numerators by each other and the denominators by each other.
3/4 * 100/1
Evaluating 3*100 and 4*1, the fraction becomes 300/4.
Now, divide 300 by 4 to get the final answer. 300/4 = 75. Therefore, 75 pounds of the students weight is water.
Answer:7 5/12
Step-by-step explanation:
12 2/3 times 4 on both sides is become 8/12
3 1/4 times 3 on both sides is 3/12
12 8/12 minus 3 3/12 equals to 7 5/12
So he worked 30.5 hours, he just didn't write some of the hours down. To find the hours he didn't write down, you subtract 8+
+
from 30.5, which equals
Number of students who play both baseball and basketball = 18+9+10-30 = 7
Probability that a student plays both sports = 7/30 = 0.233 = 23.3%
