The surface area of a cube is 1,014^2. Find the volume of the cube.
Marta_Voda [28]
Let the length of one side of the cube be x.  Then the surface area of the cube is A = 6x^2 = 1014 cubic units.  We want the cube volume, so must first solve for x and then cube the result:
       
                               1014 cu. in.
x = square root of  ----------------- = sqrt(169) = 13
                                        6

The volume of this cube is thus (13 units)^3 = 4826809 cubic units.

-y-x=0<br> Write in y=Mx+b
Ymorist [56]

Answer:

y = (-1)x

Step-by-step explanation:

What you are to do here is to "rewrite -y - x = 0 in the slope-intercept form y = mx + b."

Start by solving -y - x = 0 for y:  -y = x or y = -x.

Rewrite this by inserting the coefficient 1 and representing b by 0:

y = (-1)x + 0

which is equivalent to y = (-1)x

Assume the total cost of a college education will be $235,000 when your child enters college in 18 years. You presently have $53
Andrei [34K]

Answer:

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $235,000

P = $53,000

n = 1 because it was compounded once in a year.

t = 18 years

Therefore,.

235000 = 53000(1 + r/1)^1 × 18

235000/53000 = (1 + r)^18

4.43 = (1 + r)^18

Raising both sides to the power of 1/18, it becomes

4.43^(1/18) = (1 + r)^18 × 1/18

1.086 = 1 + r

r = 1.086 - 1

r = 0.086

r = 0.086 × 100 = 8.6%
