Question

question 9 1 pts the equation for density is d = m / v where m is mass and v is volume. what equation does one get when v is moved \up and over\ and what variable becomes isolated? vd = m, m is isolated; v / d = m, m is isolated; 1 / v = md, no variable is isolated; d / v = m, m is isolated question 10 1 pts which of the following shorthand operations effectively isolates the variable v in the density equation d = m / v? move v down and over, move d up and over; move v up and over, move d up and over; move v up and over, move d down and over; move v down and over, move d down and over

Explanation:

Step1: Solve Question 9

Given $d=\frac{m}{V}$, multiply both sides by $V$.
$d\times V=\frac{m}{V}\times V$

Step2: Simplify the equation

$Vd = m$, and $m$ is isolated.

Step3: Solve Question 10

Starting with $d=\frac{m}{V}$, to isolate $V$, first multiply both sides by $V$: $dV = m$. Then divide both sides by $d$, which is equivalent to moving $d$ down and over. So we move $V$ up and over first and then $d$ down and over.

Answer:

Question 9: $Vd = m, m$ is isolated
Question 10: move V up and over; move d down and over
