D
The number of hours the plumber works is the dependent variable in the relationship, and he earns $270 for 9 hours of work.

Step-by-step explanation:

number of hours  worked 2 = money earned $60,

so we can conclude that

the money he earned depend on the hours worked (independent variable) and that

number of hours  worked 1 = money earned $30

A. True

hours worked IS the independent variable

9 hours of work = 9*$30  = $270 IS correct

B. False

money earned IS the dependent variable

9 hours of work is NOT $540

C. False

the money earned is NOT independent

for 9 hour will NOT earn $540

D.True

the number of hours IS dependent variable

the 9 hours of work IS earning $270

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
