Answer:
a = -0.5
b = −1.73
c = −0.70
d = 
≈ -0.70710678
Step-by-step explanation:
EXPLAIN Q(a):
sin(−30)
Use the property sin(−x)=−sin(x).
−sin(30)
Get the value of sin(30) from trigonometric values table.
-0.5
10^1=10
10^2=100
10^3=1000
10^4=10,000
The power multiplies the number by itself the number of the power. When multiplying 10 to the power of any number, just make the number of 0's in the final number equal to the exponent.
10^34 will be a 1 with 34 zeros on the end.
There can be 6 teams because 2 is the lowest number that can go into both 12 and 18. (12/2) = 6...and I know (18/2 = 9) but there wouldn't be enough boys to make 9 teams
there will be 6 teams each containing (12/6) = 2 boys and (18/6) = 3 girls
