Answer:a)

90 pitches totalb)

27 hitsc)

63 pitches (either ball or strike)Step-by-step explanation:Every pitch is:

BALL, STRIKE, HIT

(one of the 3)

a)

Given, 60% of total pitches were strikes, that is 54 of them. So we can say:

54 is 60% of total

Let total be “t”, so we can write:

54 = 60% * t

Solving for “t”:

Hence,

total 90 pitchesb)

60% = strikes

10% = balls

Remaining = 60 + 10 = 70

100 – 70 = 30%

So, 30% of total were hits.

30% of 90

0.3 * 90

27 hitsc)

We know 10% were balls, so

0.10 * 90 = 9 balls

We know 54 were strikes

So, either ball or strike = 9 + 54 = 63

63 pitches (either ball or strike)
