Answer:
112x m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+ b2) h
where b1 and b2 are the bases
A = 1/2 ( 11x+17x) * 8
= 1/2 ( 28x)8
= 112x m^2
Givens
Male = 138,053,563
Female = 143,368,343
Total
The total equals 281 421 906
Percents
Male = (138,053,563 / 281 421 906) * 100 = 49.1%
Female = ( 143,368,343/ 281 421 906) * 100 = 50.94%
Rounded
Male = 49
Female = 51
Comment.
To find this %s you could just use the first 3 digits of everything.
Total = 138 + 143 = 281
% male = (138/281) = 49.1
% female = (143/281) * 100 = 50.88
These give you the same answers when rounding.
3 and a half hours
Half and hour for 7 days is 3.5 hours
2x² + 5x - 3 = 0, 2) 3x² + 14x - 5 = 0, 3) (7 - 3x)(x + 2) = 4
