The volume v of a rectangular box in terms of its length l, width w, and height h is given by the formula v=lwh.

part a
choose the formula for the width of a rectangular box, in terms of its volume and other dimensions.
a. w=vhl
b. w=hlv
c. w=vlh
d. w=lvh
part b
find the width w of a box with volume v = 120 cm3, l = 3 cm and h = 5 cm.

width =
cm

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
