Since the data represented by the table are linear, then the average rate of change is given by the slope of the line.
 We have then:
 m = (y2-y1) / (x2-x1)

 Substituting values we have:
 m = (9-10) / (1 - (- 1))

 Rewriting we have:
 m = (-1) / (1 + 1)

 m = -1/2
 Answer:
 
The average rate of change is given by:

The interior angles of a triangle add up to 180

180 - 97 - 34 = 49

150 / Sin 34 =  b / Sin 49

multiply both sides by Sin 49

(Sin (49)* 150) / Sin 34 = b

b = 270.39 feet

Jim, Dan and David share some sweets in the ratio 3:1:5. Jim gets 21 sweets. How many more sweets does David get over Dan?
nadezda [96]

Answer:

David gets 28 more than Dan

Step-by-step explanation:

Jim: Dan : David: total

3   :    1    :  5       : 3+1+5 = 9

Jim gets 21

21/3 = 7

Multiply each number by 7

Jim: Dan : David: total

3*7 :  1*7  :  5 *7  :  9*7

21  :   7     :  35   :  63

David has 35 and Dan has 7

35-7 = 28

David gets 28 more than Dan
