A valley is 94 feet below sea level. what is the ab solute value of the elevation difference between the valley and the sea level?
write the problem and evaluate.
Problem: What is the absolute value of the elevation difference between a valley that is 94 feet below sea level?
Evaluation: The absolute value of the elevation difference is the distance between the two elevations, regardless of their direction. In this case, the elevation of the valley is 94 feet below sea level, so the absolute value of the elevation difference is 94 feet. Therefore, the answer is:
|94| = 94.
Donald is 110 feet above sea level. Mickey is 70 feet below sea level. How far apart are donald and mickey?
Write the problem and evaluate.
Problem: If Donald is 110 feet above sea level and Mickey is 70 feet below sea level, how far apart are they?
Evaluation: To find the distance between the two elevations, we need to add their absolute values. In this case, Donald is 110 feet above sea level, so his elevation can be represented as +110. Mickey is 70 feet below sea level, so his elevation can be represented as -70.
To find the distance between Donald and Mickey, we can add the absolute values of their elevations:
|110| + |-70| = 110 + 70 = 180
Therefore, Donald and Mickey are 180 feet apart.
mercy drops a penny into a pond. The penny drops 1.5 inches every second. How many inches below the surface will it be after 8 seconds?
Write the problem and evaluate.
Problem: Mercy drops a penny into a pond. The penny drops 1.5 inches every second. How many inches below the surface will it be after 8 seconds?
Evaluation: To solve this problem, we need to multiply the rate of descent (1.5 inches per second) by the time elapsed (8 seconds) to find the total distance the penny has dropped.
1.5 inches/second x 8 seconds = 12 inches
Therefore, after 8 seconds, the penny will be 12 inches below the surface of the pond.
The temprature at 2:00 pm is 27. At 2:00 am the temprature has fallen to -4. What is the difference in the temprature from 2:00 pm to 2:00 am?
To find the difference in temperature from 2:00 pm to 2:00 am, we need to subtract the temperature at 2:00 am from the temperature at 2:00 pm.
27 - (-4) = 31
Therefore, the difference in temperature from 2:00 pm to 2:00 am is 31 degrees.
A penguin drops a pebble into the sea. The pebble drops 2 inches every second. how many inches below sea level. does it drop after 6 seconds.
The pebble drops 2 inches every second, and we want to know how many inches below sea level it is after 6 seconds. We can use multiplication to find the total distance it has dropped:
2 inches/second x 6 seconds = 12 inches
Therefore, after 6 seconds, the pebble is 12 inches below sea level.
A penguin drops a pebble into the sea. The pebble drops 2 inches every second. how many inches below sea level. does it drop after 6 seconds.
