Question

64 l = how many ml?
75 watt light bulb is 6,250 mA what us this current in amperes?
4,046.9 m 2^ = ( ) km 2^ ?

Answer 1

1 liter = 1000 ml so 64 l= 64000 ml

1 meter squared = 1.0 × 10-6 kilometers squared,
so 4,046.9m 2= .0040469 km2

idk about the second one

Answer 2

1 L = 1000 mL

So in order to convert 64 L to ?? mL:
64 L x (1000 mL / 1L) = ??? mL
Notice that the unit L cancels out leaving your answer in mL.

Do the same with 6,250 mA: 1 milliamperes = 0.001 amperes
6,250 mA x (0.001 A / 1mA) = ??? A

And finally, 1 meter^2 = 1.0 x 10^-6 kilometers^2
4,046.9 m^2 x [ (1.0 x 10^-6 km^2) / 1 m^2 ] = ??? km^2

Hope this helps!

Good luck!

Answer 3

Subtract 2x from each side of the second equation, so it becomes y=1-2x. Then substitute the second equation into the first and solve for x. 1-2x=5x+15. Add two x to each side and subtract 15 from both sides. -14=7x. Now divide each side by 7, so x=-2. Then plug x into either equation and solve for y. Using the first equation, y=5(-2)+15, y=-10+15, y=5. Then you can use the second equation to check. 2(-2)+5=1, -4+5=1. It checks. The thing about algebra is to always to remember to do the same operations on both sides of the equal signs.

Answer 4

64 l = 64,000 ml

6,250 mA = 6.250 A

4,046 m 2^ = 0.000004046 km 2^

am I not correct?

Answer 5

64 liters x 1000ml/l = 64,000ml
6,250mA / 1000mA/A = 6.25 amperes
4046.9m^2 / 1,000,000m^2/km^2 = 0.0040469km^2

Answer 6

64,000 ml
6.25 amperes
0.004069 km^2

Answer 7

64,000 ml
6.25 amperes
0.004069 km^2

Answer 8

64000 mI
6.25 Amperes
4.0469

Answer 9

The whole point of homework is so YOU learn something dumbass.
