Samuel has an ant farm with a volume of 375 cubic inches. The width of the ant farm is 2.5 inches and the length is 15 inches. W

Alexxandr [17]

Answer:

Step-by-step explanation:

From the given information, it is clear that the shape of ant form is rectangular prism.

Let us write formula for volume of rectangular prism (ant form)

V = l x w x h

Use the formula to write an equation.

Plug V = 375, w = 2.5 and l = 15

375 = 15 x 2.5 x h

375 = 37.5 x h

Divide both sides of the equation by 37.5

375/37.5 = (37.5 x h)/37.5

10 = h

Hence, the height of the form is 10 inches.

Determine if the matrix below is invertible. Use as few calculations as possible. Justify your answer.

Marysya12 [62]

Answer:

This shows 3 pivot position matrixes.

Step-by-step explanation:

The given matrix is:

$\left[\begin{array}{ccc}1&-2&-5\\0&4&3\\-3&3&0\end{array}\right]$

The option D is correct for this matrix.

The matrix is invertible and the given matrix has 3 pivot positions.

The matrix is invertible if its determinant is nonzero.

Multiply the 3rd row by 1/3.we get:

$\left[\begin{array}{ccc}1&-2&-5\\0&4&3\\-1&1&0\end{array}\right]$

Now, add the first row with third row:

$\left[\begin{array}{ccc}0&-1&-5\\0&4&3\\-1&1&0\end{array}\right]$

Replace third row by first row:

$\left[\begin{array}{ccc}-1&1&0\\0&4&3\\0&-1&-5\end{array}\right]$

This shows 3 pivot position matrixes.

Hence, a matrix is invertible and has 3 pivot positions.
