Three quantities x, y and z are connected so that x varies directly as z and inversely as the square root of y. If x=6 when z=12 and y=25,find the expression for x in terms of y and z

The expression for x in terms of y and z is x = or x =

Step-by-step explanation:

The relationship between x, y and z can be expressed as;

x α

x = C × , where C is a constant of proportionality

Now, given the values of x, y and z, we can have that;

6 = C ×

6 = C ×

C = 6 × = 2.5 or

Putting the value of C in the equation, we have;

x = or

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
