SIZIF [17.4K]

Answer:

Scale = 1\ in : 8\ ft

Step-by-step explanation:

Given

Scale\ Measurement = 20.5in

Actual\ Measurement = 164ft

Required

Determine the scale

The scale is calculated using the following ratio:

Scale = Scale\ Measurement : Actual\ Measurement;

Substitute values for Scale and Actual Measurements

Scale = 20.5\ in : 164\ ft

Divide ratio by 20.5

Scale = 20.5/20.5\ in : 164/20.5\ ft

Scale = 1\ in : 8\ ft

This implies that: <em>1 inch on scale represents 8 ft in actual measurement</em>

I need serious help with this one.
SpyIntel [72]

Answer:

Try 20.

Step-by-step explanation:

To round 19.5 to the nearest whole number consider the tenths’ value of 19.5, which is 5 and equal or more than 5. Therefore, we have to round up: the whole number part of 19.5, 19, increases by 1 to 20, and the decimal point and all digits (.5) are removed.

19.5 rounded to the nearest whole number = 20
