The difference in elevation is 7,716 ft
y > the elevation of Mt Owens
x > the elevation of the bolo cavern
we know that
To find the difference in elevation between the bolo cavern and Mt Owens, subtract the elevation of the bolo cavern from the elevation of Mt Owens
y=7,295 ft > is positive because is above sea level
x=-421 ft > is negative because is below sea level
d. millimeters per hour.
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'.
