The rate of discharge is 1,54,550 cubic meter/sec.

This is the problem related to conversion of units. We need to convert cubic feet into cubic meter here.

Also we know that 1 foot = 0.305 meter.

The rate of discharge of water is given as 5,500,000 cubic feet per second.

So, now to convert to cubic meter we need to divide the given rate by cube of 0.305.

Now discharge in cubic meter per second = [tex]5,500,000*(0.305)^{3}[/tex]

The percentage increase is the ratio of value increased to the original value and multiplied by 100.

The percentage increase in his hourly wage between year 1 and year 2 is 15.61%.

Option A is the correct answer.

The percentage increase is the ratio of value increased to the original value and multiplied by 100.

It is expressed in percentage.

If there is an increase in the value of anything, then there is an increase in percentage.

We have,

Wage in the first year per hour = $8.65

Wage in the second year per hour = $10

The percentage increase in hourly wage:

= [ (10 - 8.65) / 8.65 ] x 100

= ( 1.35 / 8.65 ) x 100

= 15.6069 %

= 15.61 %

(A) The expression to represent the elevation level of city D, in feet will be :  [tex]D = \frac{1}{4} * [C][/tex]    
(B) The elevation of city D will be -6 feet. The negative here shows that city D is below sea level.

In the question, it is given that city A is 96 feet below sea level, city C is 24 feet below sea level, and the elevation of city D is 1 over 4th of the elevation of C. Since, City A & C are both below sea level their elevation will be negative. So, by these we get elevations:

For City A,  A = -96

      City C,  C = -24

      City D,  [tex]D = \frac{1}{4} *[C][/tex]      ----> Equation (1)

By Equation (1) we get the representation of elevation for City D.

Now, Calculating the elevation of city D, we will put the value of city C in equation (1).

        =>   [tex]D = \frac{1}{4} *[-24][/tex]

        =>   [tex]D = -6\\[/tex]

The negative sign here shows that the elevation is below sea level for city D.

What are coordinates?

A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Given that Sanjay determined that one vertex of a figure was mapped to its image by translating the point 2 units left and 7 units down.

In order to translate coordinates, 2 units left we need to subtract 2 units from the x-coordinate of the point, while to translate the point 7 units down we need to subtract 7 from the y-coordinate of the point.

Therefore, the rule that maps the other vertices of the figure to their images is, (x¹,y¹)=(x-2,y-7), or it can bse written as T<-2,-7> (x, y),

where x¹ and y¹ are the coordinates of the points after transliteration.

The ratio of non-black sedans to black sedans is 40/31, as of the given condition.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,

The total number of sedans in the parking lot is,
496 black sedans + 640 non-black sedans = 1136 sedans.

The ratio of non-black sedans to black sedans can be found by dividing the number of non-black sedans by the number of black sedans:

Ratio = 640 non-black sedans / 496 black sedans
Ratio  = 640/496

The scale used on the map is 1 centimeter to 12.5 kilometers.

When we do a scale drawing of something in scale (like a map, that represents a given location) the dimensions suffer a change of scale.

This means that each unit on the scale drawing not represents the same unit on the original thing.

On this case we have a map where a actual distance of 50 kilometers is represented by a distance of 4cm (this means that each 4cm in the map are equivalent to 50 kilometers in the actual place).

Then the scale will be in cm to km, and to get the scale we can write:

4cm = 50km

Dividing both sides by 4 we get:

1cm = 50km/4 = 12.5 km

Then we conclude that the scale used for the map is 1 centimeter to 12.5 kilometers.
