A radio tower casts a shadow 8 feet long at the same time that a vertical yardstick casts a shadow half an inch long.How tall is

Lapatulllka [165]

The height of radio tower is 576 feet approximately

<em><u>Solution:</u></em>

Given that, radio tower casts a shadow 8 feet long

At the same time that a vertical yardstick casts a shadow half an inch long

To find: height of radio tower

Let "x" be the height of radio tower

length of shadow of tower = 8 feet

Length of shadow of stick = $\frac{1}{2} \text{ inch}$

Convert inch to feet

$1 \text{ inch } = \frac{1}{12} \text{ foot }$

$\frac{1}{2} \text{ inch } = \frac{1}{2} \times \frac{1}{12} \text{ foot } = 0.0416 \text{ foot }$

Thus,

Length of shadow of stick = 0.0416 feet

Length of vertical yard stick = 3 feet (since 1 yard = 3 feet )

Therefore, by proportion we get,

$\frac{\text{ height of radio tower }}{ \text{ length of shadow of tower }}=\frac{\text{ Length of vertical yard stick}}{\text{ Length of shadow of stick }}$

Substituting the values we get,

$\frac{x}{8} = \frac{3}{0.0416}\\\\x = 8 \times 72.11\\\\x = 576$

Thus height of radio tower is 576 feet approximately

Measure the diagonal of a square whose area is exactly one square foot. Is the diagonal length closer to 1.5 or 1.4 feet? Explai

kondor19780726 [428]

It is closer to 1.4

Step-by-step explanation:

This is a 45 45 90 triangle

To find the hypotenuse of this triangle it is any side length times the square root of two.

Formula: Square Root = sqrt

Hypotenuse = SideLength*sqrt(2) ; 1*sqrt(2) = 1.412...

Rounded to the nearest tenths it is closer to 1.4 than 1.5
