Answer:
2/5
Step-by-step explanation:
First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.
10-5=5
6-8=-2
5/-2= -5/2
A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.
-2/5
--2/5
2/5
Have a wonderful day! :D

Answer:
The value of the third reading is 80 F
Explanation:
Let x represent the value of the third reading.
The average of a set of data equals the sum of all the data divided by the number of data;
Given;
Average = 80 F
Sum of data = 65+85+x+90
Number of data = 4
substituting we have;
solving for x;
Therefore, The value of the third reading is 80 F
1 9.3
____ = ____
1000 x
x=9300
9300/100=93
x=93 meters
