Answer:
speed of light movement when boat is 1 mile from light house is 0.029 miles/sec
Step-by-step explanation:
Given data:
distance of boat from light house is 2 miles
rate of turning of light is 100 degree per minute
w = 100 degree/min

w = 1.745 rad/min
w = 0.0290 rad/sec
speed of movement of light 

thus speed of light movement when boat is 1 mile from light house is 0.029 miles/sec
Answer:
Step-by-step explanation:
1. Symbolically, we get: 62 - 5x < 40
2. y - 7.3 < 3.4. Solve for y by adding 7.3 to both sides, obtaining:
y < 10.7 This is both the 'range' and the 'solution'
3a) 4b = 9b + 45, or -5b = 45, or b = -9
3b) 5a + 10 = 4a - 4
Combining like terms results in a = -14
Answer:
CP of 1bulb =Rs10
CP of 250bulbs=Rs2500
Number of defective bulbs 12
remaining bulbs =250−12=238
SP of 1bulb =Rs12
SP of 238bulbs=Rs2856
profit=Total SP-CP=2856−2500=Rs356
