You can solve this one by adding their rates, but you have to invert the numbers they give you to find the rate. Rate is measured in something per unit of time, and "per" indicates division. So the rates are: 1/3 of an hour (Sally) and 1/6 of an hour (Steve). So add the rates: 1/3 + 1/6 = 1/2. (1/3 is 2/6, and 2/6 + 1/6 = 3/6). Since their combined rate is 1/2 of a room in one hour, it takes them two hours to paint the room.
This answer makes sense: It takes Sally three hours by herself; with Steve's help, she's faster, but not THAT much faster, because he's pretty slow. You can often spot-check word problem answers like this by giving it a common sense once-over. If we came up with four hours, that would clearly be wrong: it should take her LONGER if she's getting help.
<span>4300 / 2 = 2150
Just simply divide</span>
I think it is 4 out of 5 but i dont know the number to the nearest thousanths
but i hope this helps
FV=(240)[1+(0.09/12)]^(12*14]
=(240)[1+0.0075]^168
=(240)(3.5088855954842)
=$842.13 ( answer )
Answer:
3.8% of 11,500 is 437 so then we would multiply 437 by 3 and get $1,311 then round and get $1,300, I don't if this is right.
