A rational number is a real number such as 5 or .25. An irrational number is a non realistic number such as pi
F(x<40)= 0.39+(x*0.24) This formula will quantify what you have written out above.
27 is the answer I believe
The area of the trapezoid is calculated through the equation,
A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,
A = 0.5(9.6 + 25)(90) = 1557 mi²
Therefore, the approximate area of the country is 1557 mi².
100x14=1400
1400 divided by 15=93.3
So your grade would still be a low A
