In order to solve this problem, you must divide 30 beads by 5 beads to get 6 pairs of purple beads. Then multiple 6 by 2 to get 12 white beads.
In ratio form, this can look like 30:12
Answer:
x = - 3 ± 3
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ±
) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ±
) / 2
= ( - 6 ±
) / 2
= ( - 6 ±
) / 2
= ( - 6 ± 6
) / 2
x = - 3 ± 3
Answer:

Step-by-step explanation:
given,
angular deceleration, α = -0.5 rad/s²
final angular velocity,ω_f = 0 rad/s
angular position, θ = 6.1 rad
angular position at 3.9 s = ?
now, Calculating the initial angular speed




now, angular position calculation at t=3.9 s



Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.
Answer:
B 6.00
Step-by-step explanation:
M= 6$
C= 9$
M+C= 6+9= 15$ per hour
