"At breakfast, he drinks 237 milliliters. At lunch, he drinks 300 milliliters. At dinner, he drinks 177 milliliters. Estimate the total amount of water Rogelio drinks. Then, find the actual amount of water he drinks at all three meals."</h3>
In order to estimate the total amount of water Rogelio drinks at all three meals, you need to follow these steps:
1. Round 237 milliliters and 177 milliliters to the nearest Tens place.
If the digit in the Ones place is less than 5, you must round down.
If the digit in the Ones place is greater than or equal to 5, you must round up.
Then:
2. Add 240 milliliters, 300 milliliters and 180 milliliters:
In order to find the actual amount of water Rogelio drinks at all three meals, just add 237 milliliters, 300 milliliters and 177 milliliters. This is:
Answer:
It is a little bit trivial:
As we know:
Energy sink: is anything that uses energy.
Energy source: is anything that produces energy.
How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)
These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.
So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.

Step-by-step explanation:
In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.
