A certain rock has a density of 12.5 g/mL. What volume will 4.0g of this rock occupy

0.32 mL

Step-by-step explanation:

d = m/v

v = m/d

v = 4.0 g ÷ 12.5 g/mL

g ÷ g cancels out the unit g

v = 0.32 mL

the correct answer is 828.07

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
