Exterior angle is equal to sum of interior opposite angles hence,

req. angle = 80 + 62 = 142

Since it is a angle on a straight line, it is basicly as simple as:

180-38=142 degrees

As there is space for half a circle above a straight line. :)

An aquarium can be modeled as a right rectangular prism. Its dimensions are 14 in by 7 in by 4 in. If the aquarium contains 153

musickatia [10]

A right rectangular prism can be used to simulate an aquarium. Its measurements are 14 by 7 by 4 inches. If there are 153 cubic inches of water in the aquarium, There is a 61 % empty space.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The volume of the aquarium is;

V=14 × 7 × 4 = 392 inch³

The % by which the container is empty is found as;

$\%Empty= \frac{392-153}{392} \times 100 \ \\\\ \%Empty= \frac{239}{392} \times 100 \\\\ \%Empty= 61\%$

Hence, there is a 61 % empty space.

Linear Algebra: Permutation Matrices Let M be the matrix {{0,0,0,1,0}, {0,0,1,0,0}, {0,1,0,0,0}, {0,0,0,0,1}{1,0,0,0,0}}. What i

FromTheMoon [43]

Multiplying M by any matrix A would return new matrix, B, in which

• the 1st row of B is equal to the 4th row of A,

• the 2nd row of B is equal to the 3rd row of A,

• the 3rd row of B is equal to the 2nd row of A,

• the 4th row of B is equal to the 5th row of A, and

• the 5th row of B is equal to the 1st row of A.

The pattern here is

1 => 4 => 5 => 1

2 => 3 => 2

Let {4, 3, 2, 5, 1} denote the matrix M, where each number refers to the row of the identity matrix, I.

Using this notation, the pattern above gives

M² = {5, 2, 3, 1, 4}

M³ = {1, 3, 2, 4, 5}

M⁴ = {4, 2, 3, 5, 1}

M⁵ = {5, 3, 2, 1, 4}

M⁶ = {1, 2, 3, 4, 5}

so that <em>n</em> = 6.

(Notice that the first cycle has length 3 and the second one has length 2; the minimum <em>n</em> needed here is then LCM(2, 3) = 6.)
