Answer:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.
Step-by-step explanation:
Hey the answer is trinomial
Answer:
.
Step-by-step explanation:
Let C represent total daily charges in dollars and t represent time in hours.
We have been given that a plumber charges $50 for a service call plus $80 per hour.
The amount charged for t hours would be 
.
The total amount charged for t hours would be 
.
We are also told that plumber spends no longer than 8 hours a day at any one site, this means that time t have a restriction as:
Therefore, our required cost function would be .
Answer:
DC
Step-by-step explanation:
ABCDE ≅ GHJDF
GH ≈ AB
DJ ≈ DC
Answer:
Mechanical advantage = Effort distance/Resistance distance
Effort distance = D - Fulcrum = 0.5 m
Resistance distance = A - Fulcrum = 2.0 m
Then,
Mechanical advantage = 0.5/2 = 0.25
Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.
