Answer:
A
Step-by-step explanation:
Given
x² = 16 ( take the square root of both sides )
= ± 
← note plus or minus sign
x = ± 4
Since 4² = 4 × 4 = 16 and
(- 4)² = - 4 × - 4 = 16
Answer: 35000π cm.
Step-by-step explanation:
First find circumference
Circumference = 2 × π × radius
Circumference = 2 × π × ( diameter / 2 )
Circumference = 2 × π × ( 35 / 2 )
Circumference = 35 × π cm
Now,
1 revolution = 1 circumference
1000 revolution = 1000 circumference
1000 revolution = 1000 × (35 × π)
1000 revolution = 35000π cm.
Total number of students in the class = 36
Number of students wearing blue shirts = (1/6) * 36
= 36/6
= 6
Number of students wearing white shirts = (2/3) * 36
= 2 * 12
= 24
Then
Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)
= 36 - 30
= 6
So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
Answer:
8.64%
Step-by-step explanation:
