Answer:
y-intecept = (0, y -value)
x-intercept = (x-value, 0)
=> y-intecept = (0, 0.4)
=> x-intercept = (0.3, 0)
Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring decimal placed after the decimal point.
let x = 0.7272.... (1) ← multiply both sides by 100
100x = 72.7272... (2)
Subtract (1) from (2) thus eliminating the recurring decimal
99x = 72 ( divide both sides by 99 )
x = =
Mutliply both sides by -1 to reverse the inequality.
Simplify.
Divide both sides by -5+√26.
After simplifying you should get the answer of
Pump A = 45 mins
Pump B = 35 mins
Pump A and B = (45 x 35) / ( 45 + 35) = 19.69 mins (nearest hundredth)

Answer: 19.69 mins
