The volume of a cube is the length of one side cubed, therefore the side length of the cube is the cubed root of the volume. Using a calculator to find the cubed root, you find that it is 0.4 meters, or answer C.

Therefore the solution is 0.4 meters; answer C.

A concert hall has 12 seats in the first row, 14 seats in the second row, 16 seats in the third row, and so on. If the pattern c

Marrrta [24]

Given:

The number of seats in the first row is a₁ = 12.

The series of the increasing number of seats is 12, 14, 16......

The objective is to find the total number of seats in the first 12 rows.

Explanation:

The difference between the number of seats in each row can be calculated by the difference between the successive terms of the series.

$\begin{gathered} d=14-12=2 \\ d=16-14=2 \end{gathered}$

The number of rows to be calculated is n = 12.

To find the number of seats:

The number of seats presents in the first 12 rows can be calculated as,

$S_n=\frac{n}{2}\lbrack2a_1+(n-1)d\rbrack$

On plugging the obtained values in the above equation,

$\begin{gathered} S_{12}=\frac{12}{2}\lbrack2(12)+(12-1)2\rbrack \\ =6\lbrack24+11(2)\rbrack \\ =6(46) \\ =276 \end{gathered}$

Hence, the total number of seats in the first 12 rows is 276.

Tommy Blox borrowed $4000 from a bank at 12% simple interest.After 3 years,he paid back the loan plus the interest.How much did

Juli2301 [7.4K]

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $4000.00.
r is the interest rate, 12% per year, or in decimal form, 12/100=0.12.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.

To find the simple interest, we multiply 4000 × 0.12 × 3 to get that:

The interest is: $1440.00
