$33.60. 20% of 40 is 8. 40 minus 8 is 32. 5% of 32 is 1.60, with a sum of 33.60, the total for the shirt.
6x is an example of a variable
Interest charged: I=prn=6700*0.135*5 = 4522.50
Total re-payment: 6700+4522.50 = 11 222.50
Step-by-step explanation:
first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).
the area is : 1/2 × perimeter × apothem
the perimeter is simply 12 × 5 = 60 meters.
apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =
= 9.330127019... meters
so the area is
1/2 × 60 × 9.330127019... = 279.9038106... m²
therefore, the third answer option is correct (although it is m², and not m³).
by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.
