Answer:
millimeters.
Step-by-step explanation:
We have been given that a leak in a water tank causes the water level to decrease by millimeters each second.
To find the decrease in water level in 5 hours let us multiply water decrease in one second by number of seconds in 5 hours.
Using the exponent product rule let us add the exponents with same base (10).
Therefore, the water level in tank decreased millimeters in 5 hours.
• Donny's bagels is the better deal.
1. It have Lower ratio.
2. Bob's bagels are 10 for $11
Unit price for Bob's bagels = $11 / 10 bagels = $1.10 per bagel
Donny's bagels are 4 for $3
Unit price for Donny's bagels = $3 / 4 bagels = $0.75 per bagel
3. Donny has the better deal, because Donny's unit price is less than that of Bob's ( each of Donny's bagels cost less than each of Bob's bagels).
