Question
Describe how to find the sum p+q using a number line if p=−19 and q=12.1.(1 point)
First find ____ on a number line, then count _____ spaces to the right.
A whale is swimming at an altitude of −42
meters and then ascends 20 meters to the surface. What is the altitude at the surface of the water?(1 point)
90.7
To find the current depth of the scuba diver, we need to add the distance she ascended to her initial depth.
The scuba diver is initially 75 feet below sea level. She then ascends 12.7 feet.
To find the current depth, we add 75 feet and 12.7 feet:
75 + 12.7 = 87.7 feet.
So, the current depth of the scuba diver is 87.7 feet.
To find the current depth of the scuba diver, we need to add the depth the diver is below sea level to the amount the diver ascends. In this case, the scuba diver is 75 feet below sea level and ascends 12.7 feet.
To get the current depth, we add the two distances:
Depth below sea level + Amount ascended = Current depth
75 feet + 12.7 feet = Current depth
Calculating this, we get:
87.7 feet
So, the current depth of the scuba diver is 87.7 feet.
