A clothing manufacturer needs 2.4 yards of fabric to make a jacket and 1.6 yards of fabric to make a matching skirt. The number of jackets, x, and skirts, y, that can be made from a 48-yard bolt of fabric can be represented by the equation 2.4x + 1.6y = 48. Graph the function and find its intercepts. What does the x- intercept represent? A. (0, 30) and it represents that 30 skirts can be made
B. (30, 0) and it represents that 30 skirts can be made
C. (20, 0) and it represents that 20 jackets can be made
D. (0, 20) and it represents that 20 jackets can be made

Aregular hexagon rotates counterclockwise about its center. it turns through angles greater than 0° and less than or equal to 360°. at how many different angles will the hexagon map onto itself?

When turned about its axis of rotation, which shape could have created this three-dimensional object?

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?
