carrots cost $.0.49 A one pound bag contains 10 carrots. The carrots cost how much?

If $0.49 is the cost per pound, then:

.49/10=4.9 cents per carrot.

A seamstress has a piece of cloth that 3 yards long. She cuts it into shorter lengths of 16 inches each. How many of the shorter pieces are there?

1 yard=3 feet X 12 inches=36 inches, so 3 yards,

3 X 36=108 inches, therefore,

108/16=6 3/4 number of shorter pieces.

It actually goes on forever but at he very very end there is a 4.

 3,531,271 / 3,438,185 =1.0271 - 1=.0271 X 100=2.71% percentage increase.

You just stated the speed of the train!

10.1 miles in 1/2 hour, so the speed per hour:

10.1 X 2=20.2 miles per hour.

which is approximately two thirds

How about this one.

Hope I've spelled it correctly !

i need help with this 1/2 -4 + 2=-3 1/2 + 2=-1 1/2

Divide (2x - 4) by (x + 2).=2(x - 2) / (x + 2)

no and why are you doing this on a maths website XD

what is -20 divided by 5/6

-20 / (5/6)=

-20 X 6/5=

-120/5=-24

cool(thinks)

-30n=-27n-63 isolate n to one side

-30n+27n=-63

-3n=-63 divide both sides by -3

n=21

10*x-4=>1.5         +4

10*x=>1.5 +4

10*x=>5.5          /10

1x=>0.55

10*0.55-4=1.5

MEANING ANY NUMBER LARGER THAN 1.5 IS CORRECT

D:{>1.5}

what is 0.6666666666666667 in a fraction

A line passing through the origin and perpendicular to the line  4x + y = k  will have a slope of (1/4) and the equation of this line will be  y = (1/4)x

And at (t, t +1 )  we have that

t + 1 =  (1/4)t

(3/4) t =  -1

t = -4/3    then t + 1  will = -1/3

And we can find k as

4t +[ t + 1 ]  = k

-16/3 - 1/3  = k = -17/3

Here's a graph of both lines and the intersection point :.......https://www.desmos.com/calculator/c5qsf7jlo2

There is no NUMERICAL solution to these "equations"!. Did you just make them up?

A chocolate bar has my tongue, though! (:

What would be the Richter level of an earthquake twice as strong as an earthquake of level 5.2 if an increase on the scale corresponds with the increase in a power of 10.

Since the Richter is logarithmic to base 10, then the increase in magnitude would be: Log(2)=0.301, so to double the strength of the earthquake, there has to be an inctrease of .301 in scale. Therefore:

5.2 + .301=or about 5.5 would be twice as powerful as 5.2 quake.
