What is the surface area of the given figure? and how did you find the answer?
a, 2,520 cm2
b, 2,792 cm2
c, 4,080 cm2
d, 2,280 cm2

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
