Answer:
The Original length of the wire is 61.1 cm.
Step-by-step explanation:
Given:
Now it has been given that the above equation can be used to find the original length in centimeters of a wire before it was cut.
Also We need to find the original length of the wire.
From above equation we can say that;
l ⇒ Original length of the wire.
On Solving the above equation we get;
Now we will add both side by 12.5 using addition property of equality.
Hence the Original length of the wire is 61.1 cm.
Answer:
14.7 km
Step-by-step explanation:
Given:
Scale of a map is 2 cm = 21 km.
We know that, 1 cm = 10 mm
Therefore, 2 cm = 2 10 = 20 mm
Therefore, the scale of the map is, 20 mm = 21 km
Now, let the actual distance be 'd' km for 14 mm.
Using proportion of the two quantities, we get:
Multiplying both sides by 14, we get:
Therefore, the actual distance of 14 mm is 14.7 km.
