That's of course the sum angle formula for sine
sin(a+b) = sin a cos b + cos a sin b
We have a=20° b=40°
sin 20° cos 40° + cos 20° sin 40°
= sin(20°+40°)
= sin(60°)
= √3/2
Answer: √3/2
Since some number added to -11 is 37, we must do 37- (-11), which is 48. Then we check our work and find that 48+-11 is indeed 37. Now we divide 48 by -12, which is -4, multiply by -8 and get a final answer of 32.
Answer: 17

Answer:
Step-by-step explanation:
Let Carlo's age = x
Equation: 6*x = 108
6x = 108
Solution:
6x = 108
x = 108/6
x = 18
Carlo's age = 18 years
Answer:
$173.06
Step-by-step explanation:
Think of "her new monthly salary" as the sum of "her monthly salary plus a 6.5% increase. Multiplying "her monthly salary" by 1.065 will produce a result that includes both the original monthly salary and the increase:
1.065($162.50) = $173.06
