2n + n = 30, that is
3n = 30 ( divide both sides by 3 )
n = 10
Thus the number is 10
So 4 triangular faces of the pyramid will have total area
<span>= 4 ×<span>12 </span>× base × height = 4 × <span>12 </span>× 34 × 58f<span>t2 </span>= 3944f<span>t2</span></span>
So <span>3944f<span>t2</span></span> of marble cover the faces of the pyramid.

Answer:
The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100
Step-by-step explanation:
Let
x ------> the amount of money that should be invested at the rate of 12%
3,000-x -----> the amount money that should be invested at the rate of 10%
we know that
The sum of the interest on each of the accounts must be equal to the total interest.
Solve for x
therefore
The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100
