Step-by-step explanation:
Answer: He cannot see a ship that is 4.5 miles away.
Step-by-step explanation:
Since we have given that

Here, h is the eye level above the water
d is the distance away.
If h = 12 feet
We will get :

Hence, it is 10.39 feet away when eye level is 12 feet above the water.
Therefore , he cannot see a ship that is 4.5 miles away.
Answer:
2x + 10 = y
Step-by-step explanation:
The term 10 more is plus 10, and 2 times the "number" which we know we can label as "x". 2x + 10 is the equation and we are told that y is the number of points so 2x + 10 = y is the answer.
Hope that helps, and have a great day!
Answer:
Step-by-step explanation:
Perimeter = 84 cm
2*(length + width) = 84
2* (2x - 8 + x - 2) = 84
2*(2x + x - 8 - 2) = 84 {bring like terms together}
2*(3x - 10) = 84 {add/ subtract like terms}
Divide both sides by 2

3x - 10 = 42
3x - 10 +10 = 42 + 10 {add 10 to both sides}
3x = 52
Divide by 3,

x= 17 1/3
Length = 2x - 8
