A group of students go out on a boat to go scuba diving. The instructor takes the group 51.89 feet below the surface to start. Then they go up 29.36 feet and stop to see some fish. Estimate the total change in distance from where they started at the surface. Find the total change in distance from where they started at the surface.

The estimated total change in distance from where they started at the surface. = +29 feet

The total change in distance from where they started at the surface = 29.36 feet

Step-by-step explanation:

Given : The instructor takes the group 51.89 feet below the surface to start.

i.e. -51.89 feet below surface

Then they go up 29.36 feet , represented by 29.36

Here 51.89 ≈ 52

29.36 ≈  29

The estimated total change in distance from where they started at the surface. = +29 feet

The total change in distance from where they started at the surface = 29.36 feet

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
