To vaporize half of the water (0.500 kg) the energy supply needed is

If the stove is supplying 20 kJ/s, the time its needed is

Answer:
C. 1.2x
Step-by-step explanation:
He pays 1 x for his haircut, and an additional 20% on top of that, or an additional 0.2x. If you write that as an expression, you can simplify it like this:

You can also work it out by multiplying by 1.2 as stated in answer C. If his haircut costs $10, adding a 20% tip of $2 is the same as multiplying by 1.2.

Answer:
m<z= 50*
m<w= 130*
m<y=130*
We already know that X is 50 so the one directly across from it is the same so it is also 50. What I like to do when I can't figure out the other angles is I subtract 180 from what I know the other angle is. so I subtracted 50 from 180 and I got 130 for W and Y.
Get back to me with info on the second question and I'll answer it.
