The stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. if the volume of the stack of pennies on the left is 375 mm3, what is the volume of the stack of pennies on the right in cubic millimeters? (hint: only enter numerals in the answer blank)

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
