Answer: D) 32
Each side of the cube is 8 units, so the perimeter of one side is 4*8 = 32.
Answer:
(E) 22,400
Step-by-step explanation:
Let b represent the amount invested in bonds. Then b/4 is the amount invested in stocks, and the total amount invested is ...
b/4 +b = 28000
5/4b = 28000 . . . . . collect terms
b = (4/5)(28000) = 22,400 . . . . . multiply by 4/5
22,400 is invested in bonds.
Answer:
Distance= 6.6 miles
Bearing= N 62.854°W
Step-by-step explanation:
Let's determine angle b first
Angle b=20° (alternate angles)
Using cosine rule
Let the distance between the liner and the port be x
X² =8.8²+2.4²-2(8.8)(2.4)cos20
X²= 77.44 + 5.76-(39.69)
X²= 43.51
X= √43.51
X= 6.596
X= 6.6 miles
Let's determine the angles within the triangle using sine rule
2.4/sin b = 6.6/sin20
(2.4*sin20)/6.6= sin b
0.1244 = sin b
7.146= b°
Angle c= 180-20-7.146
Angle c= 152.854°
For the bearing
110+7.146= 117.146
180-117.146= 62.854°
Bearing= N 62.854°W
