Answer:
I don't believe that it will be viable by the time i am a senior, because the USA is so in debt, and they are having enough trouble as it is, supporting today's retirees and seniors. I wish it would be viable, but it is highly unlikely the government will not be able to support it.
Step-by-step explanation:
Part 1: I'm pretty sure B is soluble in water.
Part 2: The data is showing that A isn't soluble at all (probably cause it's solid or a lipid or something) because the amount undissolved stays the same as B changes in solubility.
Answer: the efficiency of the first car is 25 miles per gallon.
the efficiency of the second car is 30 miles per gallon.
Step-by-step explanation:
Let x represent the efficiency of the first car.
Let y represent the efficiency of the second car.
Distance = car efficiency × number of gallons.
The first car consume 25 gallons of gas and the second consumed 15 gallons of gas. The two cars Drove a combined total of 1075 miles. It means that
25x + 15y = 1075- - - - - - - - - - -1
The sum of the fuel efficiencies was 55 miles per gallon. It means that
x + y = 55
Substituting x = 55 - y into equation 1, it becomes
25(55 - y) + 15y = 1075
1375 - 25y + 15y = 1075
- 25y + 15y = 1075 - 1375
- 10y = - 300
y = - 300/-10
y = 30
x = 55 - y = 55 - 30
x = 25
The domain is (-5,4). If that makes any sense, if it doesnt ill explain
