Answer:
Option D
Step-by-step explanation:
The complete question is attached herewith. 
Also the options for the same are as follows - 
What is the meaning of the slope of the trend line shown on the scatterplot?  
A A plant grows about 3 inches for every 2 hours of sunlight it receives.  
B A plant grows about 2 inches for every 3 hours of sunlight it receives.  
C A plant grows about 3 inches for every 1 hour of sunlight it receives.  
D A plant grows about 1 inch for every 3 hours of sunlight it receives.
Solution
If we look at the graph, we can see that in 6 hours the tomato plant grew by 2 inches. 
At the X axis, when x = 6 hours, the y co-ordinate at X = 6 hours is 2 inches. 
Hence, It can be interpreted that 1 inch of the tomato plant grows in 3 hours. 
Hence, option D is correct
 
        
             
        
        
        
Answer:
B: 57 mph=57 mph
Step-by-step explanation:
A steady pace means constant speed  that it does not change over a period of time and direction of motion. A simple formula, for this case (constant speed)

 where x is distance and t time. The subtract is final value minus initial value
We have the distance and time, then

ANSWER
The smaller angle is 

.EXPLANATION
Let the angles be 

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.
This implies that,

If one angle is 4 times the other, we can then write the following equation,

We put equation (2) into equation (1) to get,


We divide through by 5 to obtain,

This implies that,
