38•2=76
360-76=284
284/2=142
The answer is 142
So you know that the area is (b*h)/2
A = (6,6*4,9)/2 = 32,34/2 = 16,17 cm^2
Since only 30% of the teachers taught for one year, the remaining percentage of the teachers had taught for more than a year, or 70%.
70%=0.7
80(0.7)=56
56 teachers had taught for more than a year.
The answer is x<20. Hope that helps.
