Answer: 39$
Step-by-step explanation: 4 hrs and 30 mins and you make 27$
You gotta make the hrs into minutes. So you can find the rate. 4 hrs is 240 minutes. With the 30 minutes its a total of 270 minutes. You're earning 1 dollar every 10 minutes. So i think if i did the math right 390 minutes is 6 hrs and 30 mins. And so she has earned 39$.
Answer:
Step-by-step explanation:
problem 4
Velocity is +2.0m/s and constant acceleration is -0.5m/s^2
For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.
problem 5
Accelerate from rest to 28m/s means go from 0 to 28m/s so with
a constant acceleration of 5.5 m/s^2 it will take 5.09 second
The answer is 20% just divide them and move the decimal 2 ways to the right
