Multiply 4x - 3(x- 2y) + 1/2 (6x - 8y)
Simplify 4x - 3x + 6y + 3x - 4y
4x + 2y
Answer:
<h2>
cos 30°= 0.866</h2>
Step-by-step explanation:
Step one:
Applying the SOH CAH TOA principle
assuming all dimensions are in cm
Step two:
Given data
opposite= 1 cm
hypotenuse= 2 cm
<h3>we can now solve for θ</h3>
Sin(θ)= opp/hyp
Sin(θ)= 1/2
Sin(θ)= 0.5
θ= sin-1 0.5
θ= 30°
hence from tables cos 30°= 0.866
125×20=2500
2500-2140=360
Your answer is correct, 360 seats are not occupied
9/250 is in it's simplest form
If you wanted it's decimal form, it is 0.036
8/12 and 4/6 and10/15 and20/30 and 40/60
