21^(1/21)*7^(1/3)

Try that on the calculator and see what happens

just make sure the calculator is set in degrees. You can either have the trigonometric function set in degrees or radians

you just add 700,445,300 and 4000000 which is 4001445 and then divide that by 4 - since there were four numbers. Which gives you 1000361 approx.

a-b(b+c)
a=-1 b=-2 c=1

a-b*(b+c)= -1--2*(-2+1) => -1+2*(-1) => -1+-2 => -1-2 => -3

2e^-x (x-u)

What do you want to do with this
do you want to expand and simplify?
do you want to get rid of the negative indice?

It does = 2(x-u) / e ^x

Is that the answer you wanted?

Aaron has a data allowance of 200MB a month, and facebook used 10MB of data per hour. How many minutes each day, on average can Aaron spend on face book without going over his data limit (answer to nearest minute)

Months can have 30 days or 31 days or 28 or 29 days. So, you are not going to get accuracy to 1 minute unless you specify which month (I'll use a 30 day month)

10*20=200
therefor 10MB per hour = 20 hours per month

20hours /30days = 2/3 on an hour each day = 2/3*60 minutes each day =>

10000 * 0.1287128712871287..=1287.128712871287

1* 0.1287128712871287 = 0.1287128712871287

(10000-1) * 0.1287128712871287 = 1287.12871287 - 0.128712871287...

9999 * 0.1287128712871287 = 1287

0.1287128712871287 = 1287 / 9999

you can now cancel down to get the most simple fraction possible.

You have to divide it by 8

The first on is 3/8 of total
THe second is 5/8 of total

To find the equation of a straight line, you first need to find the gradient;
Gradient=change in y/change in x
For our case we get,
(-4-1)/7-(-3)=-1/2
To find the equation, we choose one point i.e (7,-4)
So to find the equation, we use the same method that the used to calculate the gradient but the second point will be unknown i.e (x,y)
So: y-(-4)/(x-7)=-1/2
The equation is 2y+x=-1

We will use this equation for an example.
(2 1/2)/(3/7) or two and a half divided by three over seven.

The easiest way is to first convert the whole numbers into fractions.
Ex. 2 1/2 (two and a half) = 5/2 (five over two)

Then you flip the second fraction around.
Ex. 3/7 (three over seven) = 7/3 (seven over three)

Then you just multiply directly across.
Ex. (5/2) * (7/3)
5 * 7 = 35
2 * 3 = 6
= (35/6) or thirty-five over six.

Make sure you simplify if at all possible.

Hi,

Avogadro's Number, 6.02214129×10(to the power of 23) is the number of atoms per mol of any substance. So in your case, multiply Avogadro's number with 6.9

I think that this is in the North Atlantic ocean, near Nova scotia, Canada.
I don't know anything about the climate except that it would be too cold for me!

So 2/17x=14
Divide each side by 2/17 to get x by itself
This is the same as multiplying by the reciprocal, 17/2
X=17/2*14
X=238/2
So x=119

One number is 2 more then 3 times another. The sum is 22. Find the numbers.

let x be the first number and y be the second number

1) write two equations
x=3y+2
x+y=22

2) Substitute in for x and solve for y
(3y+2)+y=22
4y+2=22
4y=20
y=...

3) solve for x by plugging in your y values into either equation

A=(pi)(r^2)

A- area in cubic feet
pi- 3.1415
r- radius in feet

GuestNov 9, 2013

You can do this in 1 or 2 steps:

You can use the volume of a cylinder formula:
V=Ah
where V is volume, A is area, and h is height*

--or--

First find the radius using area of a circle formula:
A=(pi)(r^2)
A is area and, r is radius*

Then use the more complete volume of a cylinder formula:
V=(pi)(r^2)(h)
where V is volume, r is radius, and h is height*

*make sure to convert so that all your numbers are in the same unit before plugging them in (4inches=0.333ft=0.111yds)- if you want an answer in cubic yards plug in r and h in yards.

Hope this helps!

The MP3 player Nicky purchased was marked 20% off the original price. At the register, the clerk took 48$ off the original price. What was the original price of the MP3 player?

48$ must be 20% of the original cost. In math, whenever you see the word "is," think "equals." Also, whenever you see "of," think multiplication.

20% of the original cost is 48$.
0.20 times the original cost = 48$
0.20(original cost) = 48
original cost = (48)/(0.20)

original cost = $240

GuestNov 9, 2013

Use the proportion:
is/of=%/100

so in this case:
48/x=20/100

and solve for x:
x=240

so the original price was $240
