The earned run average (ERA) a of a baseball pitcher varies directly as the number of earned runs r and inversely as the number
7nadin3 [17]

Answer:

The number of earned runs is 28.

Step-by-step explanation:

Earned runs average:

The earned runs average of a pitcher is the number of runs the he/she gives each 9 innings on average.

Find the number of earned runs when the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.

Solved by proportions, using a rule of three.

For each 9 innits, the pitcher gives 2.25 runs. How many runs for 112 innings?

9 innings - 2.25 runs

112 innings - x runs

Applying cross multiplication:

9x = 2.25*112

x = \frac{2.25*112}{9}

x = 28

The number of earned runs is 28.

The perimeter of the shaded face of this cube is 12 centimeters. What is the volume of the cube in cubic centimeters?
Varvara68 [4.7K]

Answer:

1728

Step-by-step explanation: L(length) H(height) W(width)

volume = l x w x h

perimeter= L + W + L + W

perimeter = 12 + 12  + 12 + 12

volume = 12 x 12 x 12 because it' s a cube, and all sides are equal

= 1728

(i don't know if it's right though...)
