The height of an object from a distance

olga55 [171]

Y = height
x = distance from tower

tan(19.9) = y/x

tan(21.8) = y/(x-50) ( x is 50 feet closer so subtract 50 from x)

find the tan of the angles:
tan19.9 = 0.362
tan21.8 = 0.400

replace those values in the equations:
0.362 = y /x
0.400 = y / (x-50)

rewrite to solve for height:
0.362x = y
0.400(x-50) = y distribute the 0.400 and rewrite as 0.400x-20 =y

now solve:

0.362x = 0.400x-20

add 20 to each side:
0.362x +20 = 0.400x

subtract 0.362x from each side:

20 = 0.038x

divide both sides by 0.038
x = 20 / 0.038 = 526.3 feet

now that x is known replace x in the original equation and solve for y:

tan19.9 = y /x

0.362 = y / 526.3
y = 0.362 x 526.3
y = 190.5

the height of the tower is 190.5 feet

Liz is shipping a package to her friend.the maximum weight of a medium flat-rate box is 20 pounds,including the box which weighs

Murrr4er [49]

Answer:

$w+0.375\leq 20$ and Liz can ship maximum 19.6 pounds.

Step-by-step explanation:

Let the possible weight of the medium flat-rate box = w pounds.

It is given that there is a box weighing 6 ounces i.e. 0.375 pounds.

Plus, the maximum weight of the package is 20 pounds.

So, we get,

The inequality representing the situation is,

Weight of medium box + 0.375 pounds ≤ Maximum weight of the package

i.e. $w+0.375\leq 20$

i.e. $w\leq 20-0.375$

i.e. $w\leq 19.6$

Thus, Liz can ship maximum 19.6 pounds.

4 square root of 6<br> over square root of 2

NeTakaya

4 square root of 6 means 4 times $\sqrt{6}$
so the equation is $\frac{4 \sqrt{6} }{ \sqrt{2} }$
we can simplify this as a fraction
remember that $\sqrt{xy}= (\sqrt{x}) (\sqrt{y})$ so
$4 \sqrt{6}=4( \sqrt{3})( \sqrt{2})$ so it is now
$\frac{4 \sqrt{3}( \sqrt{2}) }{ \sqrt{2} }= (\frac{4 \sqrt{3}} {1} )( \frac{ \sqrt{2} }{ \sqrt{2} })= (\frac{4 \sqrt{3}} {1} )(1)=4 \sqrt{3}$
