Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches
The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches
The streetlight is 12 ft 5 1/3 inches tall.
15% of 125 = 18.75 the tip
125 + 18.75 = 143.75 full price
