Answers

Answer 1
Rounded the answer should be 6 seconds, because the gravity of earth accelerates objects at 9.8 meters per second, and then 51 divided by 9.8 is 5.21 rounded to get 6
Answer 2

Niagara Falls is 51 meters high. When we dropped a ball off the ledge, the amount of time required to hit the water is approximately 5.20 minutes.  

What are Niagara Falls?


Three waterfalls collectively known as Niagara Falls are located at the southern end of Niagara Gorge and form the border between the Canadian province of Ontario and the American state of New York. Horseshoe Falls, which crosses the international border between the two nations, is the greatest of the three. The Canadian Falls is another name for it.

As we know that the gravity of earth acceleration = 9.8 m/s

The height of Niagara Falls = 51 m

So the time taken by the ball = 51 / 9.8

                                                = 5.20 minutes

Thus, Niagara Falls is 51 meters high. When we dropped a ball off the ledge, the amount of time required to hit the water is approximately 5.20 minutes.

Which method is the best way to keep from running late on the day of a test?

setting the alarm to ring fifteen minutes later than usual
picking out clothes quickly in the morning
laying out needed supplies the night before
getting to class just after it starts

Answers

It would be the third answer choice. Laying out everything you need before the day is smart so you are not late. Also studying weeks before is a great idea. I hope this helps, and have a great day!

The method that is best to keep from running late on the day of a test is;

C: laying out needed supplies the night before

When preparing for any major event including a test, it is always good to plan properly such that one is not properly prepared on the day of the event or one doesn't get late as a result of last minute arrangements which could have been done a long while prior to that day of the event.

Now, looking at all the given options, the most appropriate method that will give the best preparation to prevent running late would be laying out needed supplies the night before. This is so as to ensure that you have nothing to lay out the morning of the test.

Answer:

Е

Explanation:

To calculate real GDP in terms of base year 1984 dollars, we need to adjust for inflation by dividing nominal GDP by the price deflator.

Real GDP = Nominal GDP / Price Deflator

In this case, we know that:

Nominal GDP in 2011 is $15 billion

The price deflator in 2011 is 200

So:

Real GDP in 2011 = $15 billion / 200 = $75 billion

We know the nominal GDP in 1984 was $10 billion, but we need to adjust the Real GDP 2011 to 1984 dollars, so we multiply $75 billion by 10/15,

$75 billion * 10/15 = $50 billion

So the value of real GDP for 2011 in terms of the base year 1984 dollars would be $50 billion,

The answer is E. $50 billion.
