The length of the subway is 850 miles. If .15 inch represents 45 miles, what is the length of the subway on the map?
Scilla [17]

Answer:

The length of the subway on the map is 2.83\ inches

Step-by-step explanation:

we know that

The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual

so

Let

z------> the scale on the map

x------> the length of the subway on the map

y------> the length of the subway in the actual

z=\frac{x}{y}

In this problem we have

z=\frac{0.15}{45}\frac{inches}{miles}

y=850\ miles

substitute and solve for x

\frac{0.15}{45}=\frac{x}{850}

x=850*\frac{0.15}{45}=2.83\ inches

Carlos says that 17.43 divided By 100 Is the same thing as doing 174.3 X 0.01 Is he correct?
Setler [38]

Answer:

Step-by-step explanation:

no. this is not true as if you simply plug it in it would not come out as the same answer. multiplying something by 0.01 and dividing it by 100 is the game but 174.3 is 10 times larger than 17.48
