Answer:
Step-by-step explanation:
Look at the picture.
No. You have to calculate the unit rate by dividing 30 and 6 which is 5. Then 40 divided by 18 which is 2.22 repeating. since they don't equal the same thing, it is false.
Answer = 1/32768
Therefore A Is the correct option
Answer:
40%
Step-by-step explanation:
just take a number, for example, 1, and do the math.
1 - 30% = 0.7.
1 - 50% = 0.5.
0.7 / 0.5 = 1.4.
thus the answer is 40%.
<span>Minute hand 9mm
Hour Hand 5mm
c2 = a2 + b2 - 2abcosC
c2 = 92 +52 - 2 * 9 *5 cosC
c2 = 96 - 90 cosC
2c dc/dt = 90 sinC dC/dt
at one o'clock:
C = 30 degrees=> sin(30) = 1/2
dC/dt = 2pi - pi/6 = 11pi/6 => -11pi/6
c2= 96 - 90 cos (30)
c = âš(96 -45âš3)
2 dc/dt = 90 * 1/2 * -11pi/6
dc/dt = -25 mm/h
hence the distance between hands is decreasing at 25 mm/hr</span>
