Mathematics
1 answer:
Eduardwww [97]3 years ago
7 0

Answer:

1) 8.7\ \frac{meters}{hour}

2) 1.92\ \frac{points}{game}

3) 1.25\ \frac{strikeouts}{inning}

4) 1.5*10^{-5}\ \frac{error}{piece}

5) 33.40\ \frac{points}{career\ playoff\ game}

Step-by-step explanation:

1) Convert mixed numbers to decimal numbers dividing the numerator by the denominator and adding the result to Whole number part:

21+0.75=21.75\\\\2+0.5=2.5

The unit rate is:

Unit\ rate=\frac{21.75\ meters}{2.5\ hour}\\\\Unit\ rate=8.7\ \frac{meters}{hour}

2) Divide 2,857 points by 1,487 games:

 Unit\ rate=\frac{2,857 \ points}{1,487\ games}\\\\Unit\ rate=1.92\ \frac{points}{game}

3) Divide 255 strikeouts by 204 innings:

 Unit\ rate=\frac{255\ strikeouts}{204\ innings}\\\\Unit\ rate=1.25\ \frac{strikeouts}{inning}

4) Divide 15 errors by 1,000,000 pieces:

 Unit\ rate=\frac{15\ errors}{1,000,000\ pieces}\\\\Unit\ rate=1.5*10^{-5}\ \frac{error}{piece}

5) Divide 5,979 points by 179 career playoff games:

 Unit\ rate=\frac{5,979\ points}{179\ career\ playoff\ games}\\\\Unit\ rate=33.40\ \frac{points}{career\ playoff\ games}

How do you solve for the central area of a polygon?
ycow [4]
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.

Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
