The question is incomplete. Here is the complete question:
A machine covers 5/8 square foot in 1/4 hour. what is the unit rate?
Answer:
2.5 square feet per hour
Step-by-step explanation:
Given:
Area covered by a machine =
Time taken to cover the given area =
Now, unit rate of the first quantity with respect to second quantity is the magnitude of the first quantity being when the second quantity is one unit.
Here, the first quantity is the area covered and the second quantity is the time taken.
So, unit rate is the area covered by the machine in 1 hour.
In order to find that, we use the unitary method and divide the area by the total time taken. Therefore,
Thus, the unit rate is 2.5 square feet per hour.
An angle of depression involves you at a point and looking downward, with your eyes as the vertex. (An angle of elevation goes up from your line of sight.)
In the picture, imagine your eyes are point A. To make an angle of depression, you look downward. The angle made is angle #1, as none of the other angles use A as a vertex.
Answer:
48 feet
Step-by-step explanation:
Distance = rate × time
d = 12 ft/min × 4 min
d = 48 ft
The diver will be 48 feet below the surface.
