1. Kelly bounces a basketball 30 times in 50 seconds. At that rate, approximately how many times will Kelly bounce the ball in 150
seconds?

kelly would of hit the ball 90 times in 150 seconds

Step-by-step explanation:

you take 30 and divide it by 50 and you get 0.6.

then you take 0.6 and times it be 150

90 times

Step-by-step explanation:

The equation set-up for if she bounces a basketball 30 times in 50 seconds is 30x=50. This means that she bounced the ball every 1 2/3 second. According to this, our next equation set-up would be 1 2/3x=150. If we divide 150 by 1 2/3, we get 90. This means that Kelly bounced the basketball 90 times in 150 seconds.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
