rewona [7]
Unfortunately, there are no given choices. However, I could provide the possible inequalities from the given problem. Converting the given to inequalities: 3.2x + 0.8y < 50 x + y = maximum There is no other limiting equation (i.e. the total cost of the books) such that the, if you wanted to maximize x, results to minimum y and vice versa.

Which pair of angle measures satisfy the condition sin J = cos K? A. 15°, 40° B. 45°, 90° C. 60°, 30° D. 80°, 100° E. 70°, 110°
vaieri [72.5K]
Sin J = cos K
sin J = cos (90 - J)
K = 90 - J

sin 60 = cos (90 - 60) = cos 30

Therefore, 60°, 30° satisfy the condition sin J = cos K.
