Answer:
30% students
Step-by-step explanation:
Let x be the number of total students of a school.
63% are girls then total number of girls = (0.63)x
37% are boys then total number of boys = ( 0.37)x
Now 23% of girls wear contacts then total number of girls
= (0.63x) × 0.23
= (0.1449x)
And 42% of boys wear contacts then total number of boys wearing contacts
= (0.37x) ( 0.42)
= (0.1554)x
Total students wears contacts = ( 0.1449x) + (0.1554x)
= (0.3003x)
Percentage of students wear contacts = 
× 100
= 
× 100
= 30%
All 30% students wear contacts.
A^2+b^2=c^2
5^2+b^2=12^2
25+b^2=144
b^2=144-25
b^2=119
SQUARE ROOT BOTH SIDES:
b=10.9
The answer is c.
Answer:
<h2><em><u>D. 4/25</u></em></h2>

Answer: Option B) 7,214
Step-by-step explanation:
The value of the digit 2 in 5,426 is 20.
-In 2,843, the place value of 2 is 2000
- In 7,214, the place value of 2 is 200
- In 43,928, the place value of 2 is 20
- In 67,452, the place value of 2 is 2
So, since he place value of 2 in 7,214 is 200; and since 200 is ten times more than 20 (i.e 20 x 10 = 200)
Thus, the answer is 7214
