Okay. So 90 yds was cut from the 230 yd yarn. 230 - 90 = 140. 1/2 of 140 is 70. 230 - 70 = 160. The yellow yarn was 160 yds longer than the blue yarn at first.

Hi do u still need the answer
The 'seconds' hand on the watch goes all the way around in 1 minute. <span>15 seconds is 1/4 of a complete 1-minute revolution. </span>So, the 2 cm is 1/4 of the way around the circle that the tip makes. This makes the full circumference of the circle 8cm.
<span>The length of the second hand will be the radius of the circle. Use the following equation: </span>
2 pi radius = circumference
Since we know the circumference, plug that in, and solve for the radius:
2 pi radius = 8 cm
radius = 8cm / 2 pi =<span> 1.27 cm</span>
Answer:
________________________________
write the equation
________________________________
multiply both numerator and denominator by √3+√2
________________________________
after multiplying numerator with √3+√2 we get→√3+√2
after multiplying denominator we get 3-2
________________________________
after subtracting 3 with 2 we get →1
________________________________
hence denominater is rationalized✓
hope it helped you:)
