Answer:
C=5
Step-by-step explanation:
use the pythagorean theorem:
a= 3
b=4
c=5
3x3x3x3x3 and so on that’s how the powers work you would have to multiply 3 times itself 20 times I sure hope this helps 3 to the 20th power would equal 3486784401
difference is monthly customer fee= 15-10 = $5
difference in minutely charge = 0.08-0.06 = $0.02
minutes it takes for plans to cost same amount= 5÷0.02 = 250 min
Answer:
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
Step-by-step explanation:
cost of the cleaning is calculated from the area of the carpets
C= the cost of the cleaning a= the area of the carpets.
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
A dependent variable is a variable which depends on other factors to exist. They take their values based on other factors. Their value is changed as a result of a change in independent variable
An independent variable is a variable which does not change as a result of the change in other factors. They take their values irrespective of external factors around them.
