The greatest amount of change in Alexandra's depth while scuba diving over a single 5-minute period would be the 15th to 20th-minute period, where she was able to go from -22.98M to -6.6M covering a 16.38M run.
Answer:
27 inches
Step-by-step explanation:
We can use a ratio to solve
10 15
---- = ----
18 x
Using cross products
10x = 15*18
10x=270
Divide each side by 10
10x/10 = 270/10
x = 27
--------------------------------------------------
Surface area of the cube
--------------------------------------------------
6(2.5 x 2.5) = 37.5m²
<em>(* Each area is 2.5 x 2.5, and there are 6 sides to the cube)</em>
--------------------------------------------------
Surface area of the rectangle prism
--------------------------------------------------
2(11 x 7) + 2(9 x 7) + 2(9 x 11) = 478m²
<em>(* The opposite side of the rectangle area is the same, therefore x2)
</em>
--------------------------------------------------
Overlapping area
--------------------------------------------------
2.5 x 2.5 = 6.25m²
--------------------------------------------------
Surface area of the composite figure
--------------------------------------------------
37.5 + 478 - 2(6.25) = 503m²
<em>(* The bottom of the cube and the top of the rectangle prism overlapped, so the area is overlapped twice, minus 2 times of that area)</em>
--------------------------------------------------
Answer: 503m²
--------------------------------------------------
