Let, after t hours costs are the same.
Mathematical equation of charges taken by first studio :
Mathematical equation of charges taken by second studio :
So,
Therefore, after 6.964 hours cost of both studio is same.
Hence, this is the required solution.
<h3>Answer:</h3>
Option A
<h3>Solution:</h3>
- First, let's find the square root of 58.
- The square root of 58 is equivalent to:
- √58≈7,62 (approximately equal to)
- Now, which two integers is 7.62 between?
- Is it between 7 and 8? Yes.
- Is it between -8 and -7? No. 7.62 is positive.
- Is it between -6 and -5? No.
- Is it between 5 and 6? No.
- Therefore, √58 is between 7 and 8.

M∠2 = 180 - m∠1 = 180 - 3x [supplementary angles<span>]
</span>In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180 <span>
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50</span>
