A farm has 140 bushels of wheat to sell at his roadside stand .He sells an average of 15 ⅗ blushes each day. Represent the total change in the number of blushes he has sold after 6 days.

93 3/5

Step-by-step explanation:

Total bushels to sell = 140

Average sale per day = 15 3/5 bushels

Total change in the number of bushels sold after 6 days ;

Average bushels sold per day * Number of days

15 3/5 * 6

(78/ 5) * 6

468 / 5

= 93 3/5

Change in number sold after 6 days = 93 3/5

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
