A10-ft vertical post casts a 12-in shadow at the same time a nearby cell phone tower casts a 126-ft shadow. how tall is the cell phone tower?

The cell phone tower is 1260 feet tall

Solution:

Given that 10-ft vertical post casts a 12-in shadow

At the same time a nearby cell phone tower casts a 126-ft shadow

To find: height of cellphone tower

We can use proportion to solve the sum

Here,

Let "x" be the height of tower

height of post = 10 feet

shadow of tower = 126 feet

shadow of post = 12 inches

We know that,

1 inches = 0.0833333 foot

12 inches = 12 x 0.0833333 foot = 1 foot

shadow of post = 1 foot

Thus the proportion becomes,

Thus the cell phone tower is 1260 feet tall

d. millimeters per hour.

step-by-step explanation:

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'.
