Find how many piranhas you can put in a cylindrical tank

mr Goodwill [35]

Answer: The correct answer is 10 piranhas.

Step-by-step explanation:

To calculate the total Volume of a cylinder we have to use the following formula:

Volume = Area * Height

Area = π * r² , where r= radius

The diameter is always the twice the radius so the diameter is 4 feet in this case and the radius is 2 feet so the area is

Area= 3.1416 * (2*2)

Area = 3.1416 * 4

Area = 12.5664 square feet

Volume = 12.5664 (area) * 1.25 (height).

Volume = 15.708 cubic feet

Each piranha needs 1.5 cubic feet so we have to divide the total Volume by the volume that each piranha needs

15.708/ 1.5 = 10.472 or ten pirahnas because we can't put a fraction of a piranha in the tank.

Answer:

(D)

Step-by-step explanation:

The graph shows the arm span lengths of the students, clearly we can see that the most of the students have arm span length in the initial points of the length.

Median = Middle frequency of the data. Here, median will be the length in the middle.

Mode = Most frequently occurring number in the data. Here the mode will be the length which most of the students has.

Clearly, most of the student has the length in the initial inches while the median will be in the middle.

Hence, mode will be less than the median.

Write an augmented matrix of each system. Then, solve each system using matrix notation. Describe the solution set in vector not

Naddik [55]

Answer:

The answer is below

Step-by-step explanation:

Given the system of equations:

x + y + 2z = 9

2x + 4y - 3z = 1

3x + 6y - 5z = 0

This system of equation can be solved using matrix. This done by first representing the equations as matrix and then solving:

The matrix form is:

$\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&2\\2&4&-3\\3&6&-5\end{array}\right] ^{-1} \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\$

$\left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}2&-17&11\\-1&11&-7\\0&3&-2\end{array}\right] \left[\begin{array}{c}9\\1\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}1\\2\\3\end{array}\right]$
