Answers

Answer:

a=5cm

Step-by-step explanation:

V=B*H

You will get base if you do this:

B=V:H

B=175:7

B=25

I'm not so good with English, side is probably a,so:

Formula for base: B=a²

Then a=√B

a=√25

Calcular la magnitud de la velocidad angular y el período de
una rueda que gira con una frecuencia de 1200 rpm.​

Answers

Answer:

The magnitude of the angular velocity is 125.66 rad / s and the period is 0.05 seconds.

Step-by-step explanation:

The computation of the magnitude and the period is given below:

First we determine the angular velocity that transforming the revolutions per minute,  

So,

ω = (1200 rev / min) ×  (2π rad / rev) × (1 min / 60s)

ω = 125.66 rad / s

Now, the period is  

ω = 2π ÷ T

T = 2π ÷ (125.66 rad / s)

T = 0.05 s

Hence,  the angular velocity has a value of 125.66 rad / s and the period is 0.05 seconds.

The area of triangle QTU is 6 square units, and the area of triangle RSU is 6 square units. The dimensions in the figure below are labeled in units. What is the area of triangle STU in square units

Answers

Answer:

The area of a triangle is 1/2BH, or 1/2 times the base times the height.

If the area = 6, and B and H must both be whole numbers.

The area of the triangle ΔSTU is given by A = 12 units²

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the area of the triangle ΔSTU be represented as A

Now , the area of triangle ΔQTU is 6 square units, and the area of triangle ΔRSU is 6 square units

So , the base of the triangle ΔSTU = 6 units

The height of the triangle ΔSTU = 4 units

So , area of the triangle = ( 1/2 ) x Length x Base

On simplifying , we get

The area of triangle ΔSTU = ( 1/2 ) x 4 x 6

The area of triangle ΔSTU = 12 units²

Therefore , the value of A is 12 units²

Hence , the area of the triangle is 12 units²

Answers

Basically, you are going to evaluate 5n - 4 from n = 1 to n = 18. Don't forget to add as you evaluate.

I will get you started.

Let n = 1 and then n = 2.

5(1) - 4 + 5(2) - 4 + the rest

5 - 4 + 10 - 4 + the rest

1 + 6 + the rest

7 + the rest

Just continue the pattern. You will then let n be 3, 4, 5, etc all the way to 18.

He was amazed at the beauty of the colorful cliffs. Albright determined that this national monument would become a popular tourist destination. The official name of the monument at that time was Mukuntuweap National Monument. It had been named in honor of the Paiutes who lived in the region. Albright thought that the name was difficult to pronounce and proposed a name change. President Woodrow Wilson renamed the monument Zion National Monument, which became Zion National Park in 1919. The number of people visiting the park increased from approximately 300 in 1914 to 1,814 people in 1919.Zion National Park is known for its many hiking trails. The shortest trail leads to one of the popular destinations: Weeping Rock, a cliff face with a hanging garden. Over the years, water made its way through the Navajo sandstone of the cliff, traveling through pores and creating canyons. Eventually, the water encountered a layer of rock that was impermeable. The water was unable to continue down, so it traveled horizontally. At Weeping Rock, the water comes through the pores of the sandstone. The amount of water that flows out of the rock can be a trickle or a stream, giving the impression that the rock is crying. Vegetation grows in shaded areas of the cliff with water coming through the rock. As the plants grow out of the rock face, they give the illusion that they are hanging in the air.In the last century, word spread of Zion National Park's many natural treasures, like the Weeping Rock. Roads, trails, and visitor centers were built. More people traveled to Zion in order to hike, horseback ride, and go canyoneering. The Zion-Mount Carmel Tunnel was constructed by 1930. Visitors still use the tunnel to travel from Zion to the Grand Canyon or Bryce Canyon. Now, park rangers are facing problems created by having too many visitors. Trails and campgrounds are overused and need repairs. Visitors are straying off the trails to create their own, thereby damaging the vegetation. Rangers are considering the best ways to protect this national park and maintain its beauty for future generations.Based on the passage, how did the existence of Navajo sandstone lead to the hanging gardens? The existence of Navajo sandstone allowed water to flow through its pores, until it reached a different type of stone, moved horizontally, and came out the side of the cliff. This water was necessary for the plants to survive, leading to the hanging gardens. The existence of Navajo sandstone led to a dry, hot climate, in which plants could not grow, except those used in hanging gardens. This dry, hot climate made it difficult for many species of plants to grow, resulting in locals planting the hanging gardens. The existence of Navajo sandstone led to the creation of many holes with soil, which hanging gardens use to grow up toward the sun. These holes with soil were used by locals to plant lush hanging gardens that visitors could help maintain when they visited. The existence of Navajo sandstone showed that Native Americans used to dwell in the area by building their houses in the cliffs. In order to decorate their homes, the Native Americans planted many different types of plants in the walls near the water.
