Answer:
17/18
Step-by-step explanation:
you have to find the common denomonator. So, the LCM (Least common multiple) 9 times 2 is 18. 6 can go into 18, 3 times. so your new fractions are 15/18 + 2/18. then you add the numerators (top numbers) and you get 17/18!

Answer:
Last choice is correct.
Step-by-step explanation:
Given that ∠C=90°, ∠B=30°, c=10
We know that sum of all angles in a triangle is 180 degree.
∠A+∠B+∠C=180°
∠A+∠30°+∠90°=180°
∠A+∠120°=180°
∠A=60°
Now we can use sin or cos whichever applicable to find missing sides
2b=10
b=5
Similarly
a=8.6602
Hence last choice is correct.

Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
