Answer:
40 * 6.5 = 260 --> D. 260.00
I believe the answer is A because its the only one that makes the most sense.
Answer:
Step-by-step explanation:
A: if both 6 and 3 are red then the probability for a red is 2/6 or 1/3, if only 3 or 6 is a red then it is 1/6
B: spinning a 1 is 1/6 probability
C: spinning an odd number is 3/6 or 1/2 as half of the numbers are odd
D: 0 probability as there are no 9
3/4. triangle FHE and triangle KMN; triangle GEH and triangle LNM
Answer:
x = 10 , 45 degrees.
Step-by-step explanation:
This seems a tricky one .
I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2
so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes
2 sin 3x cos 2x - cos 2x = 0
cos 2x ( 2 sin 3x - 1) = 0
so 2 sin 3x = 1
sin 3x = 1/2
giving 3x = 30 degrees and x = 10 degrees
or cos 2x = 0
so 2x = 90
giving x = 45 degrees.
