b. 1.27 minutes
c. 2.27 minutes
d. 1.27 seconds
Answer:
1.27 minutes
Step-by-step explanation:
Emmett ran a mile in 9.73 minutes
Kate ran a mile in 10.87 minutes
Rubin ran a mile in 8.46 minutes.

Number of minutes Emmett ran - Number of minutes Rubin ran
= 9.73 minute - 8.46 minutes
= 1.27 minutes
Option b is correct
PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
A because the graph of a direct proportion crosses the origin.
