Answer:
This can be shown as an inequality. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound, and subtract it from the rounded value for the lower bound.
I hope it's helpful!
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!!

Answer:
y = 2x + 3
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 2
y-intercept <em>b</em> = 3
<u>Step 2: Write function</u>
y = 2x + 3
The time taken is 
<h3>Distances</h3>
Given the following information:
- Distance from Neptune to Mars =
- Time is taken =
Get the time taken:
Time = Distance/Speed
Time = 
Time = 0.89 * 10^5
Time = 8.9 * 10^4hrs
Hence the time taken is
