When is -12.5 "more than" -6.25 ?
vocabulary: elevation (vertical position), depth (distance below sea level)
suppose we discovered two mermaids underwater: mermaid a and mermaid b. we can say that they live
below sea level. mermaid a is found 12.5 miles below sea level and mermaid b is found 6.25 miles below
sea level.
we can also say that mermaid a is found at an elevation of 12.5.
and mermaid b is found at an elevation of-6.25.
on the number line below
o draw a squiggly line across the page to represent sea level and label it
ograph the locations of mermaid a and b.
poor

mermaid b
conclusion
mermaid a is found at a depth of
- 12.5
mermaid a is found at a depth of
mermaid b is found at a depth of

The intensity on a screen 70 ft from the light is 1.728 foot candle.

Step-by-step explanation:

Given that,

The magnitude of  intensity of light varies inversely as the square of the magnitude of distance D from the source.

That is

Then,

Given that,

The magnitude of intensity of illumination on a screen 56 ft from a light is 2.7 foot-candle.

Here,

=2.7 foot-candle, = 56 ft

=?, = 70 ft.

foot-candle

The intensity on a screen 70 ft from the light is 1.728 foot candle.
