the surface area of the cube is 1350

the surface area of the pyramid is 495

the total surface area is :
$1350 + 495 = 1845$

Can somone pls help me with this I have a C- in math and I really need help also a like show work on each one plsss

Lady bird [3.3K]

Answer:

1. $\frac{3}{8}$

2. $\frac{1}{4}$

3a. $-\frac{1}{4}$

3b. 3

3c. $-\frac{4}{5}$

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

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

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

$m = \frac{3-2}{-2-2}$

$m = \frac{1}{-4}$

$m = -\frac{1}{4}$

3b.

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

$m = \frac{-1 - 2}{-1-0}$

$m = \frac{-3}{-1}$

$m = 3$

3c.

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

$m = \frac{1 - (-3)}{-1-4}\\$

$m = \frac{4}{-5}\\$

$m = -\frac{4}{5}$

4.

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