Find the elapsed time.
from 4:49 p.m. to 5:18 a.m.

4:49pm + 12=4:49am

4:49am to 5:18am=11minutes + 18minutes=29 minutes,

So, the total elapsed time is:

12 hours and 29 minutes.

Always give an example of what you have in mind.You can always make one up.

Total the fruits . . .

13 + 27 + 14 + 26 = 80

Divide each by the total to obtain each fruits fractional portion and the probability of a random student selecting that fruit as a favorite.

Bananas= 13/80 = 16.25%

Apples = 27/80 = 33.75%

Pears = 14/80 = 17.50%

Grapes = 26/80 = 32.50

----------

Lancelotlionk’s favorite fruit is a Banana.  Mine is Liberace. 

The greatest common factor would be 3

please what percentage of 80 is 91.66/115

91.66/115=0.7970

0.7970/80=0.0099625

0.0099625 X 100=0.99625%, so that:

91.66/115 is .99625% of 80

Find the elapsed time.
from 3:26 a.m. to 7:50 p.m.

7pm +12=19 hours

19 - 3=16 hours elapsed

50 - 26=24 minutes elapsed, so the total time elapsed is:

16 hours and 24 minutes.

all about?!?!?!?!

i know this is latin though 

I made a math qustion to see your guys reaction.

y=x^2*4x-5

x=2y^2*5y-59

x and y have many roots, most of them "complex". Here are just two "real" roots:

x=1.1946 and y=1.81908

Huh?

If you started with variables, like x, then it means that there are unlimited answers.

hello Love Math,

               thank you very much

3 and 3/4

Agree with Guest 2    I made a typo      

f-18   NOT f-19

Use the distributive property to multiply through both of the terms then simplify:

3(-2f+1)  =    -6f +3

7(f-3)     =     7f - 21

Now add them together:

-6f + 3 + 7f - 21 =  f -19

Yep,........so?

Already answered a VERY SIMIALR question just below this one....see explanation there...

To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total

TWO of the six are lemon    2/6 x 100 = 33.33% Lemon    the rest is water  100-33.33= 66.67% water

OR

FOUR out of the SIX are water    4/6 x 100 = 66.67% Water

I'm not QUITE sure what you are asking.....

I will assume the circle CIRCUMFERENCE is 15cm

then the arc length will be a fraction of 15

there are 360 degrees in the whole circle and you wnat to know 28 degrees worth of the circumference, so

28/360   x  15   =   1.16666667 cm

~jc

Simplify the following:
3 (1-2 f)+7 (f-3)

3 (1-2 f) = 3-6 f:
3-6 f+7 (f-3)

7 (f-3) = 7 f-21:
7 f-21-6 f+3

Grouping like terms, 7 f-6 f-21+3 = (7 f-6 f)+(3-21):
(7 f-6 f)+(3-21)

7 f-6 f = f:
f+(3-21)

3-21 = -18:
Answer: |   f -18
 

Gotta be careful here....one item is in GRAMS and the other is in KILOGRAMS  (Anne REALLY likes bananas!)

1000gm in a KILOGRAM

so:

5894gm + (2456)(1000) =    2461894gm

~jc

There is an ifinite set of answers (the graph of this is a LINE of possible answers)       ....but here is one    4,1

Pick a value for 'x'    then solve for the 'y'

say x=6   then   6- 2y =2   4=2y   y=2        so   6,2 is another pair

x-2y=2

x-2 = 2y

(x-2)/2 = y       Use the graph fxn on the calculator to look at all of the possible answers

~jc

x  ¹      xˉ¹       Takes a lot of work to copy the superscripts from your character map.    Search for 'character map' on your computer and you can copy and paste all sorts of symbols.  Some computers allow you to 'map' keys for the special characters, but again it's easier to just  x^(-1)

Hayley.....    Nope, you didn't guess it.

i did not meen you but thx

Use the distributive property to multiply through both of the terms then simplify:

3(-2f+1)  =    -6f +3

7(f-3)     =     7f - 21

Now add them together:

-6f + 3 + 7f - 21 =     (-6f+ 7f)  +  (3-21)   =  f -19
