Hi!
First find how much you were off by.
14-12=2
Now set up a proportion and cross multiply to solve.
2 x 100 = 200
200/14 = 14.29
The answer is
14.29%
The standard algorithm is the way or steps to find an answer.
Answer:
Part 1: 7/3 degrees/hour
Part 2: 28/3 degrees
Step-by-step explanation:
Part 1:
3 1/2 degrees per 1 1/2 hours =
= (3 1/2)/(1 1/2)
= (7/2) / (3/2)
= 7/2 * 2/3
= 7/3 degrees/hour
The rate is 7/3 degree per hour
Part 2:
In 4 hours, the temperature goes up 4 times what it goes up in 1 hour.
4 hours * 7/3 degree/hour = 28/3 degrees
A. Always because imagine a line where one is y=x and the other is y=-x+1. The point of intersection would be (1,1)
Both should be yes..there is exactly one x input for every y input
