Answer:
20%
Step-by-step explanation:
20% of 50 is 10, and they spent 10 hours walking.
We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:
The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
Answer:
x=(T-2y)/2
Step-by-step explanation:
6.9 x 100 = 690
6 x 100 = 600
0.9 x 100 = 90
600 + 90 = 690
The formula of the area of a trapezoid is equal to:
Area = (a+b) / 2 * h
Substituting the values.
9 = (2.4 + 3.6) / 2 * h
9 = 6 / 2 h
9 = 3h
h = 3
So the height of the trapezoid is equal to 3m.
