Answer:
x = 16.5
Step-by-step explanation:
Use pythagorean theorem
a² + b² = c²
Plug in terms
7.1² + x² = 18²
Square each term
50.41 + x² = 324
Subtract a from c
x² = 273.59
Find square root
16.5
Answer:30x=840 30 represents the number of days and x represents miles per day
b)yes because 30 (28)= 840 miles
c)yes because 30(40)= 1200 miles and the question said at least 840 so it can be more
d)30(11)=330
e) 10,800- 4,015 miles =6785 miles will be saved

Answer:
Ratio
Step-by-step explanation:
Voltage measurement of batteries involves ratio level of measurement because it has a significant zero i.e. zero voltage of the battery will mean no voltage. The mathematical operations of multiplication, division, addition and subtraction are meaningful in ratio level of measurement. The mathematical operations of multiplication, division, addition and subtraction on voltage measurement of batteries are meaningful.
Thus, voltage measurement of batteries involves ratio level of measurement.
