Max observes the zoo and the library from a helicopter flying at a height of 100 times square root of 3 feet above the ground, w

poizon [28]

Answer:

The distance between zoo and library is 200 feet....

Step-by-step explanation:

Look at the picture. As the figure describes,

Let H denote the position of Helicopter.

Z denote the position of Zoo.

and L denote the position of library.

Hence, we will firstly find the distance between G and zoo and then we find the distance between G and library and subtract the first distance from second to obtain the distance between zoo and library.

In ΔHGZ.

tan 60°=HG/GZ

√3=100√3/GZ

Hence, GZ=100 feet.

Similarly in ΔHGL

tan 30°=HG/GL

1/√3=100√3/GL

GL=300 feet.

Hence, the distance between zoo and library is:

GL-GZ

=300-100

=200 feet.

Hence, the distance between zoo and library is 200 feet....

storchak [24]

Alex is correct the book would cost $18.52 before taxes adding 10% tax the book would cost an additional $1.85 for a total of $20.37. This would be just under the $21.00 that both Alex and Laura had to spend. Laura tried to combined the 35% discount which you cannot do. So yes they both would be able to purchase the book.

Translate each English phrase in the following problem into an algebraic expression and set up the related equation. Let z be th

Ede4ka [16]

The English phrase of the obtained equation is 12 times z subtracted by 3. The obtained equation after solving is 12z -23

<h3>What exactly is simplification?</h3>

Simplifying means making something easier to do or comprehend, as well as making something less difficult.

Given data;

z be the unknown number

Given conditions;

1. The difference between a number and −23.

2.−23 is equal to the product of the number and 13.

The mathematical form of the given phrase is;

⇒ z - (-23) = z × 13

⇒z+23 = 13z

⇒12z -23

The English phrase of the obtained equation is 12 times z subtracted by 3.

Hence the simplification of the given expressions is 12z -23.
