Find the total area for the pyramid with the equilateral base.

Another name for pyramid with an equilateral base, could be a square pyramid. It could also be a triangular pyramid.

I have included a picture of each of these nets to show you the areas that would need to be calculated.

To find the area of the services on an equilateral based pyramid, you would need to find the area of the base, and the area of one triangle (lateral face). All the triangular area's leading up to the point on a pyramid would be congruent.

This means if it is a square pyramid you would have four congruent triangles.

If it is a triangular pyramid you would have three congruent triangles in addition to the triangular base.

Answer:

Line A and Line C are parallel

Step-by-step explanation:

<u>Slope Equation: </u> $m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

<u>Step 1: Find the slope of the first line</u>

Line a passes through (-1, -2) and (1, 0).

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

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

$m=1$

<u>Step 2: Find the slope of the second line</u>

Line b passes through (4, 2) and (2, -2).

$m = \frac{(-2- 2)}{(2 - 4)}$

$m = \frac{-4}{-2}$

$m=2$

<u>Step 3: Find the slope of the third line.</u>

Line c passes through (0, 2) and (-1, 1).

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

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

$m=1$

Answer: Line A and Line C are parallel

A turkey cost $1.05 per pound. There are going to be 15 people at the Thanksgiving dinner. Plan for each person to eat two, 3/8

lina2011 [118]

Answer:

It will take 135 minutes or 2 hours and 15 minutes

Step-by-step explanation:

What we need here is to get the total

amount in pounds of turkey to be cooked

each person eats 3/8 pound servings

Total pound per person would be 3/8 * 2 = 3/4 pound servings

From what we have, there are 15 people at the dinner,

The total pounds to cook will be

15 * 3/4 = 45/4 pounds

Per pound of turkey, it takes 12 minutes

For 45/4 pounds, it will take

45/4 * 12 = 135 minutes

Let us convert this to hours

That will be 2 hours and 15 minutes
