The area of the figure is 22.785 square yards

The figure is a triangle, and it has the following properties

Base = 9.3 yards

Height = 4.9 yards

The area of the figure is calculated as

Area  = 0.5 * Base * Height

So, we have

Area = 0.5 * 9.3 * 4.9

Evaluate

Area = 22.785

Hence, the area of the figure is 22.785 square yards

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 %

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

Option A is the correct answer.

A scalar quantity, speed is defined as the size of the change in an object's or particle's location over time or the size of the change in an object's position per unit of time.

In statistics, a percentile (or centile) is a metric that expresses the value at or below which a specified percentage of observations in a collection of observations fall. The value (or score) below which 20% of the observations may be found is called the 20th percentile, for instance.

A higher percentile for speed is preferable for runners in a race. A high percentile indicates a faster, greater speed.

40% of athletes completed their runs at 7.5 mph or less (slower). 60% of athletes covered at least 7.5 miles per hour (faster).

10.6% is equivalent to 1/9.43 as a fraction in the lowest terms.

To convert 10.6% to a fraction in the lowest terms, we divide the percentage by 100 and simplify if necessary.

10.6% can be written as 10.6/100.

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 10.6 in this case.

10.6/100

= (10.6 ÷ 10.6) / (100 ÷ 10.6)

= 1/9.43

Since 1 and 9.43 do not share any common factors other than 1, the fraction 1/9.43 is already in its lowest terms.

Therefore, 10.6% is equivalent to 1/9.43 as a fraction in the lowest terms.

A coordinate system is geometry is a system that employs one or more integers, or coordinates, to define the position of points. The rules that maps the other vertices of the figure to their images is T<-2, -7> (x,y).

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.

Hence, the rule that maps the other vertices of the figure to their images is T<-2,-7> (x, y,).

(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.

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.

Answer: the ratio is 1.13

Step-by-step explanation:

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
Ratio = 40/31
