Answer:
6.34 (4 repeating)
Step-by-step explanation:
√36 = 6
6.34 (4 repeating) --> 6.3444
6.34 (34 repeating) --> 6.3434
Add all the prices together:
3.50 + 10.00 + 9.95 + 6.25 = 29.70
He has 30, so he had 30 - 29.70 = 0.30 left over for fish.
The two fish cost 4.50 + 4.50 = 9.00
He would need 9.00 - 0.30 = $8.70 more money

Answer:
2 sqrt(15)
Step-by-step explanation:
sqrt(60) = sqrt(4*15) = 2 sqrt(15)
f(x) = (3x+5)/7
Step 1:
we write f(x) as y
y=(3x+5)/7
Step 2:
switch y by x and x by y
x=(3y+5)/7
Step 3:
solve for y,
x=(3y+5)/7
multiply both sides by 7
7x=3y+5
subtract 5 from left side
3y=7x-5
divide both sides by 3
y= (7x-5)/3
f⁻¹ (x) =(7x-5)/3
