A cylinder has a volume of 8792 cubic units. If the height is 7 cubic u it’s which of the following is the radius

Answers

Answer:

20 units

Step-by-step explanation:

Volume of a cylinder = πr²h

V = πr²h

height, h = 7

V = π * r² * 7

V = 8792

8792 = 21.991148 * r²

r² = 8792 / 21.991148

r² = 399.79722

r = √399.79722

r = 19.99unit

r = 20 units

A merchant sells goods which cost $240 for $299. What percentage is his profit of the cost price?​

Answers

Answer:

24.58%

Step-by-step explanation:

Given that,

Initial cost = $240

Final cost = $299

We need to find the percentage in his profit of the cost price.

Profit = Final cost - Initial cost

= $299 - $240

= $59

Percentage,

[tex]\%=\dfrac{59}{240}\times100\\\\=24.58\%[/tex]

So, the required percentage is equal to 24.58%.

Answers

Answer:

From least to greatest, the correct order is: [tex]-\frac{157}{20}[/tex]; -7.666....; -7.64; and [tex]\sqrt{50}[/tex].

Step-by-step explanation:

Since [tex]\sqrt{50}[/tex] is the only positive number, that means that it will be the greatest number on the list. [tex]-\frac{157}{20}[/tex] is equivalent to -7.85, which makes it the smallest number. So you can conclude that the correct order is [tex]-\frac{157}{20}[/tex]; -7.666...; -7.64; and [tex]\sqrt{50}[/tex].

Joel went to the market to buy a juicy watermelon and found the volume was 523.6 mm. what is the radius of the watermelon? round to the nearest whole number.

Answers

Answer:

The radius of the watermelon was 5 milimeters.

Step-by-step explanation:

Since Joel went to the market to buy a juicy watermelon and found the volume was 523.6 square mm., To determine what is the radius of the watermelon, the following calculation must be performed, knowing that the volume of a sphere is equal to four thirds multiplied by pi, multiplied by the radius cubed:

4/3 x 3.14 x X^3 = 523.6

4.186 x X^3 = 523.6

X^3 = 523.6 / 4.186

X = 3√ 125.06

X = 5

Therefore, the radius of the watermelon was 5 milimeters.

How much money can you take out each month if you expect to live another 25 years?

Answers

Answer:

  $2,104.33 at the beginning of the month, or

  $2,111.35 at the end of the month

Step-by-step explanation:

The amount you can withdraw at the end of the month is given by the annuity formula ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where principal P is earning annual rate r for t years

  A = $400,000(0.04/12)/(1 -(1 +0.04/12)^(-12·25)) ≈ $2,111.35

If the withdrawal is at the beginning of the month, then the amount is less by a factor of (1+0.04/12) ≈ 1.003333. It will be $2,104.33.

You will need
lbs of the cheaper nut
and
lbs of the expensive nut.

Answers

Answer:

I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.

Step-by-step explanation:

Since I have one type of nut that sells for $ 4.50 / lb and another type of nut that sells for $ 8.00 / lb, and I would like to have 28 lbs of a nut mixture that sells for $ 7.80 / lb, to determine how much of each nut will I need to obtain the desired mixture, the following calculation must be performed:

8 x 0.95 + 4.5 x 0.05 = 7.825

8 x 0.94 + 4.5 x 0.06 = 7.79

0.94 x 28 = 26.32

26.4 x 8 + 1.6 x 4.5 = 218.4

218.4 / 28 = 7.8

Thus, I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.

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. The first angle in a quadrilateral is 150 degrees.
