Answer:
u = - 
Step-by-step explanation:
Given
t = - rsu ( multiply both sides by - 1 )
- t = rsu ( divide both sides by rs )
-
= u
Answer:
3.33 hours
Step-by-step explanation:
Take the total bill minus the flat charge. ($300 - $50 = $250)
Then take that amount and divide by the charge per hour.
($250/$75) = 3.33 hours
Answer:
Step-by-step explanation:
givens
x1 = 3
x2 = 4
y1 = 4
y2 = 7
formula
d = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )
solution
d = sqrt( (3 - 4)^2 + (4 - 7)^2 )
d = sqrt ( 1 + 3^2)
d = sqrt( 1 + 9)
d = sqrt( 10)
82-10=72
72/6=12
answer is 12
