A rectangular field is 24 yards in length and 81 feet in width.

1 answer:

4 0

Ok,
First, you have to make the measurements in feet. 24 yards = 72 feet
Then do 72 x 81 = 5832 square feet

Then,
First, you have to make the measurements in yards. 81 feet = 27 yards
Then do 24 x 27 = 648 square yards

Hope this helps :D

Help me <br>ans should be well explained

Finding diagonal sum

$\\ \sf\longmapsto 0.7+1.0+1.3$

$\\ \sf\longmapsto 0.7+2.3$

$\\ \sf\longmapsto 3.0$

Observing the square

x=0.9
y=0.6

$\\ \sf\longmapsto xy=0.9(0.6)$

$\\ \sf\longmapsto xy=0.54$

15 less than quadruple a number w

vichka [17]

Answer:

4w-15

Step-by-step explanation:

For expressions that have "more than/less than" , that number goes AFTER the "whatever a number" statement because that's just how they explain it. I don't remember the exact reason why, but that is how my professor made me remember it, and yes, the order WILL affect the expression since that's a specific topic and I suppose you're being tested on how to make algebraic expressions based on descriptions.

Use determinants to find out if the matrix is invertible.

wariber [46]

Answer:

The matrix is not invertible.

Step-by-step explanation:

We are given the following matrix in the question:

$A =\left[\begin{array}{ccc}-5&0&1\\-1&3&2\\0&10&6\end{array}\right]$

Condition for invertible matrix:

A matrix is invertible if and only if the the determinant is non-zero.

We can find the determinant of the matrix as:

$|A| = -5[(3)(6)-(2)(10)]-0[(-1)(6)-(2)(0)] + 1[(-1)(10)-(3)(0)]\\|A| = -5(18-20)+(-10)\\|A| = 10-10\\|A| = 0$

Since the determinant of the given matrix is zero, the given matrix is not invertible.
