If s = 1/4 unit and A = 80s^2
A = 80 (1/4)^2
A = 80 (1/16)
A = 5
Answer

How much of a 40 g sample would be left after 90 years
We have been given an image of a trapezoid. We are asked to find the measure of angle M and N.
We know that bases of trapezoid are parallel and the two angles between two parallel lines are supplementary, so we can set an equation as:







Upon substituting value of y in measure of angle M, we will get:




Therefore, measure of angle M is 110 degrees.
Similarly, we will find the value of angle N as:




Therefore, measure of angle N is 70 degrees.
2[3 + (10 - 4)^2] = 2[3 + 6^2] = 2[3 + 36] = 2[39] = 78
