Well, first do height times width times depth, so 2 times six times eleven. so what's 12 times eleven? 132. Now multiply 132 times two and get 264. Your answer is 264.

PLEASE HELP!! (50 POINTS)

Answer:

Since pair of opposite sides are parallel and adjacent sides meets at right angles, the quadrilateral COAT is a rectangle.

Step-by-step explanation:

The vertices of the given quadrilateral is $C(2,0),O(7,0),A(7,2),T(2,2)$

It is sufficient to show that pair of opposite sides are parallel and adjacent sides are perpendicular.

The slope of each side can be found using the formula;

$m=\frac{y_2-y_1}{x_2-x_1}$

Slope of CO,

$M_{CO}=\frac{0-0}{7-2}=\frac{0}{5} =0$

A line with a zero slope is a horizontal line.

The slope of OA,

$M_{OA}=\frac{2-0}{7-7} =\frac{2}{0}$

This slope is undefined.

A line with an undefined slope is a vertical line.

This shows that,the side CO and OA of the quadrilateral meets at right angle.

The slope of AT,

$M_{AT}=\frac{2-2}{7-0}=\frac{0}{5}=0$

This is also a horizontal line.

The slope of TC,

$M_{TC}=\frac{2-0}{2-2} =\frac{2}{0}$

This also a vertical line.

This implies that, side TC and side AT meets at Tat right angles and TC is parallel to OA.

Also AT is parallel to TO.

This shows that COAT is a rectangle.

HELP DUE IN 10 MINUTES!! WILL GIVE BRAINLEST IF CORRECT!!!!

Answer:

Given equation:

y = 10x - 32

To find the y-intercept, evaluate the equation with x = 0:

y = 10*0 - 32
y = 0 - 32
y = -32

To find the x-intercept, evaluate the equation with y = 0:

0 = 10x - 32
10x = 32
x = 32/10
x = 3.2

7. What type of angle pair are LMS and SMN? 1.adjacent angles 2.linear pair 3.complementary angles 4.vertical angles

steposvetlana [31]

In this question we have a diagram given. ANd on the basis of that diagram, we have to find the relationship between angles LMS and SMN.

As we see in the diagram, that these angles are one after another. ANd such angles are known as adjacent angles . So these two angles are adjacent angles .

So out of the four options, the correct option is the first option .
