Answer:

352 m^2

Step-by-step explanation:

Each of the four congruent triangular faces has an area that is half the product of the base edge length and the slant height:

A = 1/2·bh = 1/2·(8 m)(22 m) = 88 m^2

Then the total lateral area is 4 times this:

LA = 4·88 m^2 = 352 m^2

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne

Mrrafil [7]

<h3>Answer: Choice C. (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

Kwasi bought `15` postage stamps for `\$8.25`. All stamps cost the same amount. How many stamps can Kwasi purchase with $22

Debora [2.8K]

The number of stamps and the cost are illustrations of unit rates

40 stamps would cost $22

The cost of 15 postage stamps is $8.25

Start by calculating the unit rate of the stamps.

$Unit = \frac{8.25}{15}$

$Unit = 0.55$

So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.

So, we have:

$Number=\frac{22}{0.55}$

$Number=40$

Hence, 40 stamps would cost $22
