Answer:
Step-by-step explanation:
c^2=a^2+b^2-2abcosC
cosC= (a^2+b^2-c^2)/(2ab)
C=arccos[(a^2+b^2-c^2)/(2ab)]
C=arccos(90^2+55^2-50^2)/(2(90)55)
C=arccos(8625)/(9900)
C=29.4 degrees
Answer:
the answer is 71/12 or 5 and 11/12
Step-by-step explanation:
8x12= 96
96+8= 104
104/12= 8 8/12
2x4=8
8+3=11
11/4= 2 3/4
11/4 x 3/3= 33/12
104/12-33/12= 71/12 or 5 11/12
Answer:
D) 6.79 x 10^7
Step-by-step explanation:
Company D has the greatest revenue because it is multiplying by 10 to the power of 7 which is the same as multiplying by 10 seven times. The least revenue is company C because it is only multiplying by 10 to the power of 4 which is the same as multiplying by 10 4 times.
6.8 x 10^7 = 68,000,000
9 x 10^4 = 90,000
68,000,000 - 90,000 = 67,910,000.
Convert this back into standard form to get 6.79 x 10^7
