Answer:
Remember that when you are making stimates, you are going to roiund to the nearest dollar. Since $3.29 is closer to 3 dollars than four dollars, Sam should use the 3 dollars figure to estimate if he can afford 4 gallons of gas.
$3+$3+$3+$3=$12
The actual value is , so $3 per gallon is indeed a god estimate.
We can conclude that the correct answer is: $3 + $3 + $3 + $3 = 12, so Sal can afford the gas.

Answer:
The weight of Pedro on Mars is 266.4 N
Step-by-step explanation:
It is given that,
Mass of Pedro, m = 72 kg
Let W is the weight of Pedro on the Mars. We know that the product of mass and the acceleration due to gravity is called the weight on an object. Mass remains same everywhere. It can be calculated as :
g is the gravitational field strength on Mars, g = 3.7 N/kg
W = 266.4 N
So, the weight of Pedro on Mars is 266.4 N. Hence, this is the required solution.

Answer:
Both boats will be 54 miles apart after 3 hours.
Step-by-step explanation:
Given that from a point on a river, two boats are driven in opposite directions, one at 7 miles per hour and the other at 11 miles per hour, to determine how many hours they will be 54 miles apart, the following calculation must be performed :
54 / (11 + 7) = X
54/18 = X
3 = X
Therefore, both boats will be 54 miles apart after 3 hours.
