Time taken to rotate 90° is 13 seconds
<u>Explanation:</u>
Given:
To complete one revolution, the searchlight takes 52 seconds
One revolution = 360°
So,
360° is completed in 52 seconds
Time taken to complete 90° is
= 13 sec
Therefore, time taken to rotate 90° is 13 seconds
Answer:
2x-5= -20
move -5 to the other side
sign changes from -5 to 5
2x-5+5= -20+5
2x= -15
divide by 2 for both sides
2x/2= -15/2
cross out 2 and 2, divide by 2 and 2 and then becomes x
x= -15/2
Answer: the answer is -6
2(n+5) = -2
2n + 10 = -2
2n = -2 - 10
2n = -12
2n *1/2 = -12 * 1/2 = -6
n = -6
Answer: 1/6
