Answer:
Step-by-step explanation:
As we can see in your attached, each square represents a whole, a unit and each square has 10 identical rectangles which represents a decimal point of 0.1.
Given that:
1.4 : 0.7
We will transform each decimal number into a natural number by multiply it by 10:
=> 1.4 : 0.7 = 14:7 = 2
The result is 2, it presents for a whole number with the value is 2 units.
So we will shade:
2 unit = 2*10 identical rectangles = 20 identical rectangles
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.
