Question 169204: Convert 2.9g/cm^3 to milligrams per cubic millimeter.: Convert 2.9g/cm^3 to milligrams per cubic millimeter. Answer by Alan3354(1427) (Show Source):
You can put this solution on YOUR website!Convert 2.9g/cm^3 to milligrams per cubic millimeter.
------------------------------
A millimeter is 1/10 of a centimeter, so a cubic centimeter (cc) is 10 mms on each side. That means a cc is 10x10x10 cubic millimeters, = 1000 cubic millimeters.
If there are 2.9 g in a cc, there is 1/1000 of that in a volume that's 1/1000 of a cm^3. See that?
So, 2.9g/cc is 0.0029g/mm^3.
It might seem difficult, but it's better than inches, feet, and 16ths of inches.
It's just moving the decimal point.

:
Let s = speed returning
then
(s-2) = speed up the hill
:
Write a time equation: Time = dist/speed
;
Time return + time out = 1 & 2/3 hrs
 +  = 1 
:
 +  = 
Multiply equation by 3s(s-2) to get rid of the denominators, results
4*3(s-2) + 4*3s = 5s(s-2)
:
12s - 24 + 12s = 5s^2 - 10s
:
24s - 24 = 5s^2 - 10s
:
0 = 5s^2 - 10s - 24s + 24
:
A quadratic equation, solve for s
5s^2 - 34s + 24 = 0
Factors to:
(5s - 4)(s - 6) = 0
:
5s = 4
s =  ; this solution makes no sense.
and
s = 6 mph is his return speed, then obviously 4 mph is his up-hill speed

Question 167301: I hope you can help me. I just went back to school and I am having so much trouble with the math (I had to start college in the "stupid math" class, and I'm STILL having trouble!). Unfortunately my math professor is not very good at explaining things. He's very nice, but he's very old, and when he's putting a problem on the board, he sometimes gets confused and gets the wrong answer, which then confuses me even more! I need to know about unit multipliers. How do you know which measurement goes where (top or bottom of fraction)? I had a homework question (which I got wrong; I know the answer, but I still cannot find out how to get that answer.
Convert 44 feet per second to miles per hour.
The answer is 38 mph, but I have absolutely no idea how they came up with that answer. I've been working on this problem for over an hour. Thank you so much for your help.

DT Answer by ptaylor(1332) (Show Source):
You can put this solution on YOUR website!1 ft=(1/5280)mi
44 ft=(44/5280)mi
1 sec=(1/60)*(1/60)=(1/3600)hr
(1 sec=1/60 min and 1 min=1/60 hr, so 1 sec=1/3600 hr)
Now lets put it togethr
44 ft/sec=(44/5280)mi/(1/3600)hr
(44/5280)/(1/3600)=(multiply numerator and denominator by (3600/1) to get rid of the complex fraction:
(44/5280)*(3600/1)/(1/3600)*(3600/1) mi/hr=
(44*3600)/5280 mi/hr=
158400/5280 mi/hr= 30 mi/hr
CK my Math----I didn't come up with 38 mi/hr but hopefully you see the approach.
P.S. I think that 30 mi/hr is correct.

DT Answer by scott8148(2759) (Show Source):
You can put this solution on YOUR website!the easiest way is to think about which unit is smaller or larger
__ with fractional quantities (like ft/sec or dollars/gal), do the numerator and denominator seperately
miles are larger than feet, so there will be fewer for the same distance
__ this means multiplying feet by a fraction LESS than one
the same is true for hours and seconds
__ but in this case, the seconds are in the denominator
__ so a smaller denominator means a larger fraction
44ft/sec __ there are 60 sec in a min, so you can go 60 times as far as in a sec
__ 44ft/sec = 2640ft/min
__ there are 60 min in an hr, so you can go 60 times as far as in a min
__ 2640ft/sec = 158400ft/hr
there are 5280ft in a mi __ 158400ft/hr / 5280ft/mi = 30mi/hr
you can also use "conversion factors" incorporating units
__ the units cancel like variables in multiplying fractions

DT Answer by gonzo(474) (Show Source):
You can put this solution on YOUR website!unit multipliers always have the same measure on opposite sides of the dividing line.
example:
60 seconds = 1 minute is the equation you start with to create the unit multiplier as required.
if you have x per second, you would multiply by 60 seconds per minute.
in equation form, this works out to be:

as you can see the seconds are on opposite sides of the dividing line.
-----
in your problem you have:
44 feet per seconds = how many miles per hour.
equations you need are:
1 minutes = 60 seconds
1 hour = 60 minutes
1 mile = 5280 feet
-----
if we work this out piece by piece, we get the following:
-----
first we convert from feet per second to feet per minute.

-----
next we convert from feet per minute to feet per hour.

-----
next we want to convert from feet to miles.

-----
the common measure is always on opposite sides of the dividing line.
 means the same thing as 30 miles per hour.
you create the fraction that way.
44 feet per second =  etc.
always start with the equality, like 1 minute = 60 seconds, and then decide which unit multiplier you want to create from that.
hope this helps.

Question 165708This question is from textbook Algebra 1 1/2 An Incremental Development Third Edition Saxon
: How do you convert 365,220 centimeters to kilometers using two unit multipliersThis question is from textbook Algebra 1 1/2 An Incremental Development Third Edition Saxon
: How do you convert 365,220 centimeters to kilometers using two unit multipliers Answer by gonzo(474) (Show Source):
You can put this solution on YOUR website!you would first convert centimeters to meters using the unit multiplier from the equation 100 centimeters = 1 meter.
you would then convert meters to kilometers using the unit multiplier from the equation 1000 meters = 1 kilometer.
-----
the unit multiplier is a fraction that is always equal to 1.
this comes from the general equation of a = b.
if a = b, then a/b = 1, and b/a = 1.
-----
in your problem, you have 365220 centimeters.
it is in centimeters and it is the numerator of the fraction 365220 / 1.
-----
the conversion equation from centimeters to meters is:
100 centimeters = 1 meter.
-----
the unit multiplier can be either:
100 centimeters / 1 meter
or:
1 meter / 100 centimeters
-----
since your number is the numerator and it is in centimeters, then the unit multiplier you want to use would be 1 meter / 100 centimeters.
this keeps the denominator of the unit multiplier the same measure as the numerator of the number being converted.
-----
365220 centimeters * (1 meter / 100 centimeters) = 3652.20 meters.
-----
your number is now 3652.20 meters and you want to convert this to kilometers.
-----
the conversion equation from meters to kilometers is:
1000 meters = 1 kilometer.
-----
the unit multiplier can be either:
1000 meters / 1 kilometer
or:
1 kilometer / 1000 meters
-----
since your number is in meters and it is the numerator of the fraction 3652.20/1, you want your unit multiplier to have meters as the denominator.
-----
your unit multiplier would be 1 kilometer / 1000 meters.
-----
3652.20 meters * (1 kilometer / 1000 meters) = 3.65220 kilometers.
-----
conversion is complete.
-----
you started off in centimeters.
you multiplied by 1 meter / 100 centimeters to convert to meters.
you multiplied by 1 kilometer / 1000 meters to convert to kilometers.
-----
your answer is:
365220 centimeters = 3.65220 kilometers

You can put this solution on YOUR website!I can only tell you how I do it. I had a very good teacher in
high school demonstrate it, and it stuck pretty good in
college.
The best way to learn is do do REALLY long coversions.
Convert cm/sec to miles/hr
OK-I've got to get rid of that cm on top
I can do it like this:
(cm)(miles/cm)
Stop and think- Why can I do this? The only way I can do it
and not change what I started out with is if the (cm/mile)=1,
then (cm)x1 = (cm).
So, as long as I have calculated the EXACT number of cm in 1 mile
or the EXACT fraction of a mile in 1 cm, then I am doing (cm)x1 = (cm)
OK
(cm)(miles/cm) = miles because the cm on top cancels with the
one on the bottom.But what if I don't know the conversion (miles/cm)?
Maybe I should try (meters/cm)
(cm)(meters/cm) = meters. But I want miles. I've got more work to do
(cm)(meters/cm)(miles/meter) = miles
Can you see that cm on top and bottom are the same as (cm/cm)
and meters on top and bottom are the same as (meters/meters)?
Again, what if I don't know the conversion (miles/meter)?
What if I only know (feet/meter)? Then I can do:
(cm)(meters/cm)(feet/meter)(miles/feet) = miles
You can look at it like this:
(cm/cm)(meters/meters)(feet/feet)(miles)
I'm left with miles which is what I want, but
it only works if my conversions are EXACTLY correct
How many miles are in 1 foot?
A very small fraction of a mile:  miles to be exact
How many feet are in a meter? Around  , but you can look it up.
If you get the idea of units cancelling on the top
and bottom, you're OK. Keep practicing long conversions to get it
right. Remember if somewhere you say (11 inches/1 foot), you'll
be wrong even if your units are correct

Answer by nerdybill(1123) (Show Source):
You can put this solution on YOUR website!First, let's convert the denominator of "hour" to "seconds":
72 miles 1 hour 1 min
--------- x ------ x ------
hour 60 min 60 sec
.
Note: notice how the like-units cancel leaving:
72 miles
---------
36 sec
.
Now, let's convert the numerator of "miles" to "meters":
72 mile 5280 ft
-------- x --------- x ------------
36 sec 1 mile 1 ft
.
Again, notice how the units cancel leaving:
(72*5280*0.3048) meters0.3048 meter
-----------------------
36 sec
Resulting in:
115872.768 meters
------------------
36 sec
Finally, we get:
3218.688 meters/sec

Question 158592: I dont understand how to do Unit Rate at all. Could someone help me on giving me step by step instructions how to?: I dont understand how to do Unit Rate at all. Could someone help me on giving me step by step instructions how to? Answer by gonzo(474) (Show Source):
You can put this solution on YOUR website!unit rate * time = number of units
the above equation is a necessary starting point.
working from that.....
let unit rate = R.
let number of units = U
let time = T
the algebraic form of the equation is then R*T=U
the unit rate is expressed in units per time
as an example:
let U = 3000
let R = 50 units per hour
let T = total number of hours
putting the values in the formula R*T=U, we get
50*T=3000
solving for T, we get
T=3000/50
T=60 hours
proving the formula is correct, we substitute all values into the original equation.
since R*T=U, and R = 50 units per hour, T = 60 hours, U = 3000 units, we get
50*60=3000 which translates to
50 units per hour * 60 hours produces 3000 units.
since 50*60 = 3000, the equation becomes
3000 = 3000
which proves the formula is correct.

------------------
A mile is 5280 feet, not inches.
To do unit conversions, include the units.
10000 inches x 1 ft/12 inches * 1 mile/5280 feet
The inches cancel, the feet cancel, you get the miles.
10000/(12*5280)
= 0.15783... miles

Question 155843: Hey you doing I'm kinda stuck on this this problem I've tried it several times. I have to use three unit multipliers to convert 576 cubic inches to cubic feet.
I've can up with 192 one time and 48 I know when I can up with the anwser 48 I'm only using 1 unit multiplier and when I do 2 I get the same number back again 576 and if I use another I would only get 48 again. I use 1ft over 12in to try and solve is that correct. If anyone could with this problem I'd gradly appreciate it. thanks: Hey you doing I'm kinda stuck on this this problem I've tried it several times.

Question 155747: the sum of 4 consecutive odd integers is 216.
solve the equation to determine the smallest integer.: the sum of 4 consecutive odd integers is 216.
solve the equation to determine the smallest integer. Answer by jim_thompson5910(9370) (Show Source):
You can put this solution on YOUR website!Consecutive odd integers follow the pattern:  ,  ,  ,  , etc...
So if "the sum of 4 consecutive odd integers is 216", then this means that the equation is
 Start with the given equation.
 Combine like terms on the left side.
 Subtract  from both sides.
 Combine like terms on the right side.
 Divide both sides by  to isolate  .
 Reduce.
 Go back to the first number (which is the smallest integer of the four)
 Plug in
 Multiply
 Add
----------------------------------------------------------------------
Answer:
So the smallest integer of the group is 51
Check:
51+53+55+57=216
216=216 ... works

If u could help me i would be very grateful! Thank You Answer by jim_thompson5910(9370) (Show Source):
You can put this solution on YOUR website!Here's one way to do it:
We know that 1 foot per second = 0.3048 meters per second. So if you want to know how many meters per second there are in 6 feet per second, simply multiply both sides by 6
6*1 foot per second = 6*0.3048 meters per second
6 feet per second = 1.82898 meters per second
So there are approximately 1.82898 meters per second in 6 feet per second.
---------------------------------------------------
Here's another way to do it:
Once again, let's say that we want to find how many meters per second there are in 6 feet per second. So take 6 feet a second and multiply it by the fraction  like this
Either way you'll get the same answer. However, I've seen the second method used more since you're able to create more complicated expressions.

4.) 85 revolutions over 2 hours to rev over sec
5.) 12 kms. to yards Answer by stanbon(18993) (Show Source):
You can put this solution on YOUR website!1.) 2km to feet
Ans: 2km(0.62 mile/1 km)(5280 ft/1 mi) = [2*0.62*5280]/[1*1*1] = 65472 ft.
--------------------------------------
2.) 375 yards to meters
Ans: 375 yds(3 ft/1 yd)(12 inches/1 ft)(1 meter/39.37inches) =
[375*3*12*1] / [1*1*1*39.36] = 39.36 meters
-----------------------------
3.) 25,200 mm to meter
Ans: 25,200 mm(1 meter/1000 mm) = 25.2 meters
------------------------------------
4.) 85 revolutions over 2 hours to rev over sec
Ans: 85 rev/2 hrs (1 hr/3600 seconds) = 0.0118 rev/sec
------------------------------
5.) 12 kms. to yards
I'll leave this one to you.
