Mr. mole left his burrow and started digging his way down.

b(t) models mr. mole's depth relative to the ground (in meters) after t minutes.

how far below the ground is mr. mole after 5 minutes?

b(t) = -2.3t - 7

Will used 20 colored tiles to make a design in art class. 5/20 of his tiles were red. what is an equivalent fraction for the red tiles?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
