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:Simple volume equation: V=bwh
b=36, w=20, h=4
Just multiply them together to get 2,880.
So the answer is 2,880 cubic feet of water
Hope this helped :)
Step-by-step explanation:
Answer:
2800 dollars probably because it's about 28 weeks and 2 days from now to June so if you multiply 100 by 28 the answer is 2800$
<span>boys = 14x
</span><span>girls = 17x
14x + 17x = 186
31x = 186
x = 186/31
x = 6
</span>boys = 14x = 14 * 6 = 84
