Complete the following steps to calculate the altitude of the parallelogram using area methods. The area of the sheet of paper i
stiks02 [169]

Based on the calculations, we have the following:

  1. The area of the sheet of paper is 96 square inches.
  2. The combined area of the triangle cutouts is equal to 36 square inches.
  3. The area of the parallelogram is equal to 60 square inches.
  4. The altitude of the parallelogram is equal to 6.51 square inches.

<u>Given the following data:</u>

  • Dimension of paper = 12-inch by 8-inch.

<h3>How to calculate the paper's area.</h3>

Mathematically, the area of the paper is given by this formula:

Area = length \times breadth\\\\Area = 12 \times 8

Area = 96 square inches.

<u>For the four (4) right triangles:</u>

  • Dimension 1 = 2 inches by 9 inches.
  • Dimension 2 = 3 inches by 6 inches.

Therefore, the combined area of the triangle cutouts is given by:

A_2= (2 \times \frac{1}{2} \times 2 \times 9) + 2 \times \frac{1}{2} \times 3 \times 6\\\\A_2=18+18\\\\A_2=36\;in^2

<h3>The area of the parallelogram.</h3>

This would be determined by subtracting the area of the four (4) right triangles from the areas of the paper as follows:

P = A_p -A_2\\\\P=96-36

P = 60 square inches.

<h3>The altitude of the parallelogram.</h3>

P = base \times altitude\\\\Altitude =\frac{P}{base} \\\\Altitude =\frac{60}{9.22}

Altitude = 6.51 square inches.

<u>Complete Question:</u>

A parallelogram is cut out of a 12-inch by 8-inch sheet of paper. There are four right triangle remnants. Two have the dimensions 2 inches by 9 inches, and the other two have the dimensions 3 inches by 6 inches. The resulting parallelogram has a base of approximately 9.22 inches.

Mga oras na iniluwal ng panahon kahulugan<br>​
Mila [183]

Answer:

Ang panahon o kalagayan ng panahon ay ang paglalarawan sa kalagayan at katangiang pangkalikasan sa labas ng tahanan, gusali o anumang tirahan ng tao, hayop, halaman at iba pang mga nilalang, na ayon sa singaw ng kalawakan o ng atmospera ng daigdig. Tumutukoy ito sa kainitan, katuyuan, kalamigan, kabasaan, katahimikan, pagka-maaraw, pagkamahangin, o pagiging maulan sa isang pook, sa isang takdang oras, na maaaring magbago. Nararamdaman, naririnig, nakikita ng tao ang epekto ng panahon at maging ang pagbabago sa kalagayan nito. Nasusukat din ang panahon sa pamamagitan ng mga termometro, barometro, barograpo, sikrometro o higrometro, panukat ng hangin, anemometro, at mga panukat ng ulan. Depende rin ang taya ng panahon sa pagdating ng kapanahunan ng tag-init, taglamig, taglagas, tagsibol at tag-ulan.[1]

1. Kepler's three laws resulted from his careful analysis of ____ data, and were not derived from a mathematical model.
Sav [38]
<h2>1. Right answer: Observational </h2>

Kepler formulated the three laws of planetary motion <u>from observations made by</u> the Danish astronomer <u>Tycho Brahe of the orbit of Mars. </u>

These laws were enunciated to mathematically describe the movement of the planets in their orbits around the Sun. However, the scientific resources existing in his time did not allow him to prove these laws. It was Newton who did it after having developed the Differential and Integral Calculus and formulating the Laws of Universal Gravitation.

<h2>2.  Right answer: Aristotelian </h2>

Aristotle mistakenly thought that the Earth was the center of the universe, thus establishing a <u>geocentric cosmological model. </u>

According to this model, Aristotle proposed that the universe (the cosmos) was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): ground, water, air and fire; and the Sun along with the fixed planets in their respective concentric spheres revolving around the Earth. The outermost sphere being that of the stars and all these external elements being made of a fifth element which he called ether.
