Answer: 0.04 meters
Step-by-step explanation:
Convert cm to meters by dividing the length by 100.
4/100= = 0.04
Answer:
1875L = 1.875x10^6 mL
multiply by density to get 2.14x10^6
multiply by percentage to get 6.63x10^4 g of NaCl (66.3 kg)
Step-by-step explanation:
1. (x−1)(5x+8)−2x+5
=(x)(5x)+(x)(8)+(−1)(5x)+(−1)(8)+−2x+5
=5x2+8x+−5x+−8+−2x+5
Combine Like Terms:
=5x2+8x+−5x+−8+−2x+5
=(5x2)+(8x+−5x+−2x)+(−8+5)
=5x2 + x + −3
2. (−2+5)(3x+9)
=9x+27
3. 2x+5−8x+12
=2x+5+−8x+12
Combine Like Terms:
=2x+5+−8x+12
=(2x+−8x)+(5+12)
=−6x+17
4. (−x+3)(−5x−2)
=(−x+3)(−5x+−2)
=(−x)(−5x)+(−x)(−2)+(3)(−5x)+(3)(−2)
=5x2+2x−15x−6
=5x2 − 13x − 6
For this case, the first thing we must do is to take into account the following transformation of units:
1 revolution = 2pi radians
1 minute = 60 seconds
Applying the transformation of units we have:
Answer:
To the nearest hundredth, the angular velocity of the drum is 78.54 radians per second.
