Answer:

<em>Surface Area: 10.24 square feet</em>

Step-by-step explanation:

In order to find the surface area, part the figure into 5 shapes;   1 being a square, the other 4 being equivalent triangles

Now find the area of the square, provided the dimensions 0.8 by 0.8:

A = 0.8 * 0.8 = 0.64 square feet

The area of the triangles are equivalent knowing that the share similar dimensions, 0.8 feet for the base and 6 feet for the height, so let us find the area of one at first:

A = 1/2 * 0.8 * 6 = 3 * 0.8 = 2.4 square feet

This means that the area of all 4 triangles are:

A = 2.4 * 4 = 9.6 square feet

The total surface area of this pyramid would then be the sum of the area of all 5 shapes, triangles and square:

Surface Area = 9.6 + 0.64 = 10.24 square feet

Cuántos metros es más alto el pico de Orizaba que el Popocatépetl​
alexira [117]

How many meters is the peak of Orizaba higher than Popocatepetl?

Answer:

Popocatépetl: 5426 m and 17,802 ft

Orizaba: 18,491 meters

Step-by-step explanation:

How long does it take to climb Pico de Orizaba?

about 15 hours

Most ascents of Pico de Orizaba will take about 15 hours from the mountain hut to the summit and back. You will usually wake up and begin climbing by 1 a.m. to reach the summit by 10 a.m. and return to the starting mountain hut by 4 p.m.

How long does it take to climb Popocatépetl?

4 hours

What is Popocatépetl?

Popocatepetl is currently a very active volcano with forested slopes and a large crater. It is the second-highest peak in Mexico, behind Pico de Orizaba (5636 meters/18,491 feet), and is generally considered to be the fifth highest mountain in North American. The name Popocatepetl is Aztec for Smoking Mountain; it is often shortened to Popo. Popo and its neighboring volcano Iztaccihuatl (17,343 ft) dominate the sky east of Amecameca. They are located less than 80 km from Mexico City and are separated from each other by ten miles of high grounds referred to as Paso de Cortes. I had the pleasure of climbing the mountain on December 18, 1992, when the volcano was still considered dormant. This is no longer the case. In the 20th century, Popo had an eruption in 1947, but on December 21, 1994, it awakened from dormancy, spewing gas and ash, which was carried by the wind as far as Puebla, 25 miles east. Surrounding towns were evacuated, and scientists have since been closely monitoring Popo for signs of a possible eruption. Ever since then the mountain has been closed to climbing. In December 2000, the mountain came alive with the biggest eruption in 1200 years and with the biggest display of "fireworks" (lava shot ~400 meters/1300 feet into the air) that has been. 30,000 people were evacuated. The first documented ascent of Popocatepetl was by the Tecuanipas tribe in 1289, but this ascent has been disputed by historians. The first Spanish ascent of the mountain was an expedition led by Diego de Ordaz in 1519. Emperor Montezuma sent ten warriors to climb the mountain sometime between 1502 and 1519. Only two of these warriors survived the climb.

Can you guys help me​
Fudgin [204]

Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

3x  + 8 = 5x - 12 \\  \frac{ - 5x \:  \:  \:  \:  \:  \:  \:   =  - 5x  \:  \:   \:  \:   \: \:  \:  \: }{ - 2x + 8 =  - 12}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \: - 8  =  - 8}{  \frac{ - 2x}{ - 2}  =  \frac{ - 20}{ - 2} }   \\ x = 10

We found the value of x which is 10.

☆Let's Now plug in.

DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38

and the other:

EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38

☆They asked for what the angle of DGF measured. So we would have to add both sides

38 + 38 = 76

☆The answer is 76

How can you tell when an equation in one variable has infinitely many solutions or no solution?
Masteriza [31]

Answer:

A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.
