Chole wants to build a storage container in the shape of a cube to hold 15.625 cubic meter of hay for her horse. Solve the equation 15.625= s3 to find he length of one side of the container.

15.625= s^3 take the cube of both sides, or cubic root.

s =15.625^1/3 =2.5m-the length of each side.

Just multiply the two numbers together. That is it.

-6i-i = -7i

Sqrt(5) x sqrt(6) =sqrt(30)

Solve for x:
5 x^2 = 30

Divide both sides by 5:
x^2 = 6

Take the square root of both sides:
Answer: |x = sqrt(6)       or         x = -sqrt(6)

The sum of two integers is 701, and the larger number is 13 more than 7 times the smaller number. Find the two integers.

Let the smaller number=n

Then the larger =7n + 13

n + 7n + 13 =701

8n =701 - 13

8n = 688 divide both sides by 8

n =688 / 8

n = 86 the smaller number.

86 x 7 +13 =615 the larger number.

What is interest on principal of 31,500 for 5 years at

1.9%?  It's for a car loan so it's not 31,500 x .019 x 5.  There is probably another calculation

If it is a car loan, then the accurate way of doing it is as follows:

1) You have to calculate a monthly payment on the loan, which comes to =$550.75 per month.

2) Then you multiply $550.75 x 60 months in 5 years =$33,045.00

3) $33,045.00 - $31,500.00 =$1,545.00 total interest on car loan for 5 years.

You were told under your first post that " there is NO SOLUTION" to your problem as it is written.

If you meant to write nP2 =56, then there is a solution. If this is what you meant, then the solution in this case of "P2" is: you take the square root of 56 and round it UP to a whole integer. So, the sqrt(56) =7.4833....=8, so that 8P2=8 x 7 = 56. You can do it in a more complicated algebraic way, but is not necessary here.

If you mean:  What is the value of  log₂16 ?

then you should turn the log into an exponential:  log₂16  =  x     --->     2^x  =  16     --->      x = 4

Find the mean of 2' 5", 22' 9", and 18' 10".

The mean of the feet is:  (2 + 22 + 18)' / 3  =  14'

The mean of the inches is:  (5 + 9 + 10)" / 3  =  8"

So, the total mean is  14' 8".

If the mean of the feet did not result in a whole number, the data for feet should be turned into inches.

=(log^2(16))/(log^2(10)) =1.4499049......

64^(-1/3) =1/4

55 - 11 + 1=45 numbers available on the keypad

45^5 =184,528,125 number of codes possible if repeats are allowed.

1 / 184,528,125=your chance of entering a code correctly by pure chance.

If one hour is sixty minutes, then you are earning one euro every 10 minutes. Divide this number in half to get the extra 5 minutes, and you are getting one and a half euro every 15 minutes.

There is a mathematical proof giving the reason why it works but it is too advanced for you to undestand.

I take your problem to mean:

3^(x^2) - 3x = 81, solve for x

x ≈ -1.98257

x ≈ 2.01632

216^1/3 =6

(27)^1/3 =3

9 over 0 is an impossible number because dividing anything by 0 is indefinite.

1/4 x 12 =3
