The scale of a map is 1 inch: 250 miles. City A is 378 miles from City B. To the nearest tenth, how far is its distance on the m
juin [17]
This is a proportion question. We can express this as an equation where the answer is x:

\frac{1}{250} = \frac{x}{378}

From there, you can just cross-multiply and divide to get:

\frac{1 * 378}{250}

A tenth of 250 is 25, so this is roughly \frac{375}{250} or \frac{17}{10}, so it'll be approximately 1.7 inches on the map.

If the measure of 0 is A radians and B degrees, then A=180B/pie
yKpoI14uk [10]
Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>
