Answer:

381 cubic inches

Step-by-step explanation:

To find the volume of the cube, use the volume formula for a rectangular prism V = l*w*h and for a triangular prism V = 1/2 l*w*h.

Rectangular prism

Substitute l = 16, w = 7, and h = 3.

V = 16*7*3 = 336 cubic inches

Triangular prism

Substitute l = 5, w = 3 and h = 6.

V = 1/2*5*3*6 = 45 cubic inches

Together the volume will be 336 + 45 = 381.

Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $cos\theta$ less than 0 which means $cos\theta$ is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since $tan\theta$ more than 0 which means $tan\theta$ is positive, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 3 (tan quadrant)

The length of a rectangular book is 2 times its width. The perimeter of the book is 42 inches. Write a system of

wel

Answer:

Mark me as brainlist

Step-by-step explanation:

P = Perimeter

L = Length

W = Width

Perimeter of rectangle = L + L + W + W

or P = 2L + 2W

You know:

P = 36 inches

L = 2W [length is(=) 2 times it's width]

W = ?

P = 2L + 2W

Substitute/plug in what you know, plug in 2W for L since L = 2W

36 = 2(2W) + 2W Simplify

36 = 4W + 2W

36 = 6W Divide 6 on both sides

6 = W Now that you know the width, you can find the length:

L = 2W

L = 2(6)

L = 12

L = 12 in

W = 6 in

PROOF

P = 2(12) + 2(6)

P = 24 + 12

P = 36
