A rectangular building with a square base is being designed to minimize heat loss. The building designers state that the volume of the building must be exactly 4000 m^3. Write an equation for y, the height of the building, in terms of x, the length and width of the base.

Answers

Answer:

y = 4000/x²

Step-by-step explanation:

The volume of the building is expressed as;

V = x²y where;

x is the length and width of the base.

y is the height of the building

Given

Volume V = 4000m³

Substitute the given volume into the equation as shown;

4000 = x²y

Make y the subject of the formula by dividing both sides by x²

4000/x² = x²y/x²

4000/x² = y

Rearrange

y = 4000/x²

Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

Can someone please help me with this question I don’t understand it. Thank you

Answers

Answer:

it is 862.5

Step-by-step explanation:

each inch is 115 miles, so if theres two inches theres double the amount that there would be if there was 1 inch, so if theres 7 inches then you would have 7 times the amount it would be if there was 1 inch, in this situation theres 7.5 so you would multiply the 115 miles by 7.5 becuase that's how many inches there is, so multiplying that is the same as adding 115 plus 115 plus 115, and so on till you get the amount you need. did this help?

An employer's accountant has announced that

$166,245?
A. $11,830
B. $55,415
C. $166,245
D. $498,735

Answers

I think it is c forgive me I f I’m wrong

The amount of budget cut from last year's budget which was $166,245 will be $54860.85 which is nearly  $55,415 from the given option. Hence the correct option is (B).

What is the percentage?

The percentage is the 1 of the hundred or simply the amount or value of any number or data in the range of 100 called percentage.

For example, if Ramesh got 87 marks out of 150 then it required a lot of attention to drawing a conclusion about Ramesh's marks but if I say Ramesh got 58% then it will be easier to think and draw any conclusion.

Given that last year budget was $166,245 and the cut was 33% so it means it will be 0.33 of the $166,245 so

$166,245 × .33 = $54860.85 but in option, it is not mentioned so the nearest answer among the option will be (B).

This eruption led to the death of 57 people, in addition to permanently changing the surrounding landscape. It is still one of the most disastrous volcanic eruptions in recent history.(2) Mount St. Helens is located in the Cascade Mountain Range in Washington, United States. It is part of the Ring of Fire, an important geological area. This area is home to over 160 active volcanos. Volcanos are active if they have erupted at least once in the last 10,000 years. Mount St. Helens is a stratovolcano. This means it is a steep, evenly shaped cone made of many layers of volcanic rock and ash. These volcanos often have explosive eruptions.(3) Before the eruption of Mount St. Helens, a bulge of rock formed on the northern side of the mountain. Then, early on May 18th, an earthquake occurred that was caused by increasing pressure inside the mountain. This led to a landslide. The force of the landslide collapsed the entire northern side of the mountain, which led to a lateral blast. Lateral blasts occur when volcanos erupt sideways, rather than at the peak. This lateral blast sent rocks flying for miles at high speeds. These blasts destroy forests, buildings, and other structures in a short amount of time. The lateral blast at Mount St. Helens destroyed an area of about 150 square miles. It destroyed forests and left debris in three-inch layers, making the situation even more disastrous.(4) When Mount St. Helens erupted, clouds of deadly ash, volcanic rock, and pyroclastic flows flew outward from the volcano. Pyroclastic flows are more dangerous than lava flows. They are made of gas and volcanic matter. The temperature inside one can reach 1832 F. They move at a speed of more than 50 miles per hour. It is impossible for humans and animals to outrun them. These flows make the eruption of stratovolcanos deadly. As a result, the forests covering the mountain were ruined. Fortunately, there weren't any towns near enough to be destroyed.(5) By the time Mount St. Helens finished erupting, a crater had formed at its top. Forests had been destroyed for miles and rivers had been blocked by debris. Clouds had even blocked out the sun in the entire state. It took years for the environment to recover.How does the fifth paragraph support the main idea of the article that the eruption at Mount St. Helens was dangerous and had lasting effects? Read the excerpt from Marbury v. Madison below.If two laws conflict with each other, the Court must decide on the operation of each....
