monthly service charge is flat. you have to pay it no matter how many therms you use.
since you've used only 25 therms, they'll charge you $0.6686/therm
so, total charge for using 25 therms in one month
= 8.8 + 25*0.6686=16.715+8.8 = 25.52
What is the charge for using 45 therms in one month?
45 = 25 + 20
so for first 25 therms they'll charge u .6686/therm, and rest of the 20 they'll charge u 0.85870/therm
8.8 + 25*.6686 + 20*.85870
25.52+17.174 = 42.694
Answer is: <span>he boiling point of a 1.5 m aqueous solution of fructose is </span>100.7725°C.
The boiling point
elevation is directly proportional to the molality of the solution
according to the equation: ΔTb = Kb · b.<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant. of water.
b - molality of the solution.
Kb = 0.515</span>°C/m.
b = 1.5 m.
ΔTb = 0.515°C/m · 1.5 m.
ΔTb = 0.7725°C.
Tb(solution) = Tb(water) + ΔTb.
Tb(solution) = 100°C + 0.7725°C = 100.7725°C.
I would say because the respiratory system brings in the oxygen for the body and the circulatory system moves it throughout the body with the blood
Answer:
amplitude
Explanation:
The amplitude of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough
