Answer:
A = 1249.5 mm²
Step-by-step explanation:
Total area is sum of area of two trapezoids
A = 13(½(28 + 35)) + 28(½(25 + 35))
A = 409.5 + 840
A = 1249.5 mm²

Answer:
N = 5; only one rate is possible
Step-by-step explanation:
The values of the sets of chips are ...
12 +9N +8N^2 +4N^3
and
2 +N +N^3 +N^4
We want to find N such that the difference in value is zero:
N^4 -3N^3 -8N^2 -8N -10 = 0
A graphing calculator can show us the roots. There is only one positive real root to this equation: N = 5.
The exchange rate N is 5. Only one rate is possible.
If the line passes through the points (-5,2) and (10,-1), then the equation of the line will be y= -1/5x+1
71% water
29% land
71:29= 2,448=> the amount of earth surface that is covered with water is ~2,5 times bigger than the amount of earth surface that is covered with land
