Answer:

M = 4.33885225095

Step-by-step explanation:

Area of the square ABFE = 10² = 100

M = 100 - (2P + Q)

Let’s calculate 2P + Q :

The area 2P + Q = area ΔABC + area of sector ACE + area of sector BCF

Note :

ΔABC is an equilateral triangle

m∠CBF = m∠CAE = 30°

area ΔABC  = (CG × AB)÷2 = (8.660254037844×10)÷2 = 43.30127018922

CG = √(10^2 - 5^2)=8.660254037844  (Pythagorean theorem)

area of sector BCF = area ΔACE = 100π ÷ 12 = (8.333333333333)π

then

Area 2P + Q = area  ΔABC + area sector ACE + area sector BCF

                      = 43.30127018922+(100÷12)π+(100÷12)π

                      = 43.30127018922+ (8.333333333333)π + (8.333333333333)π

                      = 95.66114774905

Conclusion:

M = 100 - (2P + Q) = 100-95.66114774905 = 4.33885225095

The cost of the five most popular items at an airport gift shop include a $12.99 decorative mug, a $2.99 postcard, a $3.49 keych
Greeley [361]

The t-shirt that cost $15.29 is worth Denmark Krone 96.93

Which country and currency are to be chosen?

I chose Denmark and her Denmark Krone as the country's currency bearing in mind that the chosen item is the t-shirt whose dollar cost $15.29

In other words, the task at hand is to convert $15.29 which is the cost of t-shirt to the Denmark Krone whose exchange is Denmark Krone 6.3394

to $1

$1=Denmark Krone 6.3394

$15.29 t-shirt=Denmark Krone 6.3394*15.29

$15.29 t-shirt=Denmark Krone 96.93

Note that even if exchange rate was rounded to 4 decimal places, it is expected based on norm or industry practice that the final amount in Denmark Krone be rounded to 2 decimal places, in other words, the shirt at the airport gift shop whose cost $15.29 is Denmark Krone 96.93  in Denmark
