The answer is 1,088
Answer:
Step-by-step explanation:
8/11 is equal to x/20
Cross multiply
8 times 16 and 11 times x
128=11x
Divide
Then you get 11/128
Divide and simplify!!
There are 12 boys and 21 girls for a total of 33 students
I’m not sure if this is right!
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.
