Answer:
Refer to explanation^
Step-by-step explanation:
As stated in the solution, 3/7 is a negative fraction.
To make it less confusing,
2/7 x (-3/7)
Multiply the numerator with the other numerator and the denominator multiply with the other. Like...
2 multiply 3 = 6 (numerator)
7 multiply 7 = 49 (denominator)
Since the 2nd fraction is a negative, the answer is negative too.
If you convert the fraction to a decimal, it gives -0.1224489796
Given:
Miguel's height:
Actual = 5 feet 10 inches
Shadow = 4 feet 2 inches
Tower's height
Actual = x
Shadow = 8 feet 9 inches
First, we need to convert the height into inches to avoid confusion.
1 foot = 12 inches.
Miguel:
5 ft x 12in/ft = 60 inches + 10 inches = 70 inches ACTUAL
4 ft x 12in/ft = 48 inches + 2 inches = 50 inches SHADOW
Tower:
8 ft x 12in/ft = 96 inches + 9 inches = 105 inches SHADOW
Ratio of Actual to shadow:
Miguel: 70 : 50
Tower: x : 105
70 : 50 = x : 105
70*105 = 50x
7350 = 50x
7350 / 50 = x
147 = x
Actual height of the tower is 147 inches or 12 feet 3 inches long.
To check:
Miguel : 70 / 50 = 1.40
Tower : 147 / 105 = 1.40
