Answer:
54
Step-by-step explanation:

1. 600 / 900 = 260/x
234,000 / 600 = 390
the length = 390 feet
2. 100/20 = d/60
100/20 = 5
d = 60x5 = 300 feet

Step-by-step explanation:
Given the expression : -600 - (-50) as explorer climbs back to the surface :
In terms of elevation :
-600 represents the initial position below the surface.
The Change in elevation from his initial position is - 50 (though the climber is moving towards the surface) ; the negative sign depicts that he is still below the surface.
Hence,
-600 - (-50)
= - 600 + 50
= - 610
Hence, the explorer moved an elevation of - 50 in the upward direction from his initial position of - 600 ; Hence, his position is - 610 ; which is still beneath the surface
Answer:
child's ticket = 4.75 adult ticket=10.75.
Step-by-step explanation:
The cost of an adult ticket is 6 more than that of a child ticket, so will be denoted by c+6. Now, we are told that the cost of four child tickets and two adult tickets is 40.50, so we can put this in an equation and solve for c:
(c+6)+(c+6)+c+c+c+c=40.50
6c+12=40.50
6c=28.50
c=4.75
Therefore the cost of a child's ticket (c) is 4.75 and the cost of an adult ticket (c+6) is 10.75.
