Question

Choose the yearly rainfall averages in scientific notation. Location Amount of Rainfall Scientific Notation, in meters
Needles, California 0.1173 m × 10
Mt. Waialeale, Hawai'i 11.4 m × 10
Puako, Hawai’i 25.6 cm × 10
Death Valley, California 57 mm × 10
Mojave, California 160 mm × 10
Hilo, Hawai'i 480 cm × 10
Use the table to locate the location with the least amount of rain and the location with the greatest amount of rain. What is the ratio of their rainfalls, respectively? Ratio = The amount of rain on Mt. Waialeale is times as much as the amount of rain in .

Answer 1

Needles, California 0.1173m x 1000mm/m = 117.3mm

Mt. Waialeale, Hawai'i 11.4m x 1000mm/m= 11,400mm

Puako, Hawai’i 25.6cm x 10mm/cm = 256mm

Death Valley, California 57mm

Mojave, California 160mm

Hilo, Hawai'i 480cm x 10mm/cm = 4,800mm   We see that Death Valley gets the least rain at 57mm.
The Death Valley value is 57mm, which we divide into the value for Needles to get 117.3/57 = 2.06. So, Needles receives 2.06 times as much rain as does Death Valley. The ratio is then 1 (57mm/57mm) to 2.06 (117.3mm/57mm).
