On a boat tour in New York Harbor, Samuel views the Statue of Liberty. He knows from a brochure that the statue is 93 meters tal
Natasha2012 [34]
From the given provided, we can form a right triangle as shown in the attached diagram. Since we have the statue's height and the angle formed between the top of the boat and the statue we can use the properties of the tangent function below.

\tan \theta = \frac{opposite}{adjacent}
\tan(26.3) =\frac{93}{A}
A = \frac{93}{\tan(26.3)}
A = 188

From this, we can see that the side adjacent to the angle has a measurement of 188 m. This is actually the distance between boat and the base of the statue. 

Answer: 188 m

sergeinik [125]

Answer:

In all, she bought 8, or three more.

Step-by-step explanation:

If 5 chicken wings are for ten dollars, that means each wing is 2 dollars.

If each wing is two dollars then you divide the sixteen dollars by 2 dollars getting 8 wings.

Solve the simultaneous equations
Contact [7]

Answer:

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Step-by-step explanation:

Given equations are:

3x+4y=30\ \ \ Eqn\ 1\\3x-y=15\ \ \ \ Eqn\ 2

There are three methods to solve simultaneous equations

  1. Elimination
  2. Substitution
  3. Co-efficient method

We will use the elimination method as the coefficients of x in both equations are already same

Subtracting equation 2 from equation 1

3x+4y - (3x-y) = 30-15\\3x+4y-3x+y = 15\\5y = 15\\\frac{5y}{5} = \frac{15}{5}\\y = 3

Putting y = 3 in equation 2

3x-3 = 15\\3x = 15+3\\3x = 18\\\frac{3x}{3} = \frac{18}{3}\\x =  6

Hence,

The solution for given system of equations is: x = 6 and y = 3

Or
