Answer:
49 litres of petrol are needed to travel from town X to town Y and back.
Step-by-step explanation:
Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.
25L of <em>p</em> (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less <em>p</em> than before it was tuned.
2%/100 = 0.02
0.02 * 25L = 0.5L
25L - 0.5L = 24.5L
Now, don't forget, at the end of the word problem we're asked how many litres of <em>p</em> would be required to travel from <em>x</em> to <em>y</em> <em><u>AND BACK</u></em>. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)
Good luck!!
Two interpolate you need two points.
Then you assume that there is a linear correlation between those points and so you can derive the value of mid point.
You have a table with median sale prices of single family homes sold for the years from 1975 to 1995.
In this case you have to use the median sale price of single family homes sold at two years: 1994 and 1995.
You assume that the prices of the table are for the end of the year, then the price sold in June 1995 is right in the middle of the sold price in1994 and 1995.
So, the interpolation will give to [price in 1994 + price 1995] / 2 = [140,400 + 141,400] / 2 = 140,900
Answer: 140,900
The answer is the third option.
m = 7.5h
The h value multiplied by 7.5 will give you the m value.
