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

Solution:

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

Expand & simplify (x-2)(x+4)

AVprozaik [17]

You have to FOIL (multiply the first, then outer, then inner, then last)

(x-2)(x+4)

First: multiply x by x to get x².
Outer: multiply x by 4 to get 4x.
Inner: multiply -2 by x to get -2x.
Last: multiply -2 by 4 to get -8.

This gives you:

x² + 4x - 2x - 8

Combine like terms to get your final answer:

x² + 2x - 8

Hope this helped!! xx

Jack is playing a game. When a player wins 3 consecutive games, the player receives 10 bonus points and then the player’s total

svlad2 [7]

Let Jack's current point is $p$

After winning 3 consecutive games, the bonus point is given by
$b(p)=p+10$

The score after 5% = 0.05 increase is
$s(p)= (1+0.05)p=1.05p$

$(s.b)(p)=1.05(p+10)=1.05p+10.5$
