The variable z is inversely proportional to x. When x is 16, z has the value 0.9375.
Setler [38]

Since z is inversely proportional to x, when x increases by a factor of 26/16, z will be multiplied by the inverse of that factor: 16/26

z=\dfrac{16}{26}\cdot 0.9375=0.5\overline{769230}=\dfrac{15}{26}

State the independent variable and dependent variable and find the slope.
Rudik [331]
Time is your independent variable, and snowfall is your dependent variable.

Slope can be found by calculating ∆y/∆x:
x =  \frac{0.06 - 0.02}{3 - 1}  \\ x =   \frac{0.04}{2}  \\ x = 0.02

Snowfall will accumulate 0.02 m every hour.

There are 48 students in a school play. The ratio of boys to girls is 5:7. How many boys are in the school play? Explain how you
mr Goodwill [35]
Boys:  x
gilrs:   y

From the text of the task:

\left \{ {{\frac{x}{y}=\frac{5}{7}} \atop {x+y=48 \rightarrow x=48-y}} \right.

Replacing x:

\frac{48-y}{y}=\frac{5}{7}\\
\\
7(48-y)=5y\\
\\
336-7y=5y\\
\\
12y=336\\
\\
y=\frac{336}{12}=28

So there are 28 girs and 20 boys
