There are 60 student in a speech contest. Yesterday, 1/4 of them gave their speeches. Today, 1/3 of the remaining students gave their speeches. How many students still haven't given their speeches?

30 students

Step-by-step explanation:

Students who gave a speech yesterday: 1/4*60 = 15 students

Remainig students from yesterday: 60 - 15 = 45 students

Students who gave a speech today: 1/3*45 = 15 students

Students who still haven't given their speeches: 60 - (15 + 15) = 30 students

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
