Nastasia [14]

Answer:

The answer is 2.715 In

Explanation:

An estimated 60% of annual precipitation in a watershed (drainage area = 20000 acres) is evaporated. If the average annual river flow at the outlet of the basin has been observed to be 2.5 cfs, determine the annual precipitation (inches) in the basin

The annual precipitation in inches in the basin is 2.715 inches.

The solution and steps is explained in the attachment.

I hope i have been able to help.

The consumer price index (CPI) for a given year is the amount of money in that year that has the same purchasing power as $100 i
Kipish [7]

Answer:

The formula should be 234.1 x (1 + 2.9%)^t

Explanation:

As the questions indicates, the CPI indicates what the value for money is in that given year compared to the base year. So a higher CPI amount is given as a result of inflation over the years. So the rate of inflation was such that the 100 dollars in 1983 (taken as the base year) is equivalent to 234.1 in 2015 as a result of inflation. So, essentially, the time value of money concept is being applied here. We can use the formula for calculating the future value of money over here as well.

The equation is: FV = PV × (1 + x%)^t

where, FV is future value, PV is the present value today, x% is the rate of change, and t is the time period in years.

With the values at hand, the formula to compute what the CPI should be t years after 2015,

CPI (t years after 2015) = 234.1 x (1.029)^t

Natasha_Volkova [10]

From an isometric view orientation resource, the four (4) typical characteristics of a front view include the following:

  1. The front view graphically shows the length and height of an object
  2. The front view has the least amount of hidden lines.
  3. The front view must be chosen first.
  4. The front view's orientation influences the other views.

<h3>What is an isometric sketch?</h3>

An isometric sketch is also referred to as an isometric drawing and it can be defined as a graphical (pictorial) representation of a physical object in technical and engineering drawings, especially by drawing all its three dimensions (3D) at full scale.

<h3>The five characteristics of isometric sketches.</h3>

In technical and engineering drawings, the five (5) characteristics of isometric sketches include the following:

  1. The final image isn't distorted.
  2. The image is in three dimensions (3D).
  3. The final image is drawn to full scale.
  4. The image are all uniformly foreshortened.
  5. They are drawn using vertical lines and horizontal lines.
