Answer:
a) <u>90 pitches total</u>
b) <u>27 hits</u>
c) <u>63 pitches (either ball or strike)</u>
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, <u>total 90 pitches</u>
<u></u>
b)
60% = strikes
10% = balls
Remaining = 60 + 10 = 70
100 - 70 = 30%
So, 30% of total were hits.
30% of 90
0.3 * 90
<u>27 hits</u>
<u></u>
c)
We know 10% were balls, so
0.10 * 90 = 9 balls
We know 54 were strikes
So, either ball or strike = 9 + 54 = 63
<u>63 pitches (either ball or strike)</u>

Answer:
FALSE
Step-by-step explanation:
A neutral atom means it does not contain any charge. In an atom positive charges are carried by protons and negative charges are carried by electrons. Neutrons are neutral and do not carry any charge.
Hence, for an atom to be neutral there should be equal number of protons and electrons balancing out each other.
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°
