Answer:

The height of the pole 129.31 feet.

Step-by-step explanation:

Length of the pole = x

Length of the wire attached to the pole = 220 feet

Angle of elevation = \theta =36^oC

According trigonometric ratios::

\sin \theta=\frac{Perpendicular}{Hypotenuse}

\sin36^oC=\frac{x}{220 feet}

0.5877=\frac{x}{220 feet}(sin36^oC=0.5877)

x =129.31 feet

The height of the pole 129.31 feet.

On a quiz, students were awarded a certain number of points for a correct answer and penalized a certain number of points for an
SVETLANKA909090 [29]
Given that the score of the student on the quiz was 25c - 10(15 - c)

It can be seen that the first term of expression for her score (i.e. 25c) shows that 25 marks were awarded to each correct answer.

The second term of the expression (i.e. 10(15 - c)) represent that 10 marks were deducted from each wrong answer.

Thus, the number of wrong answers is 15 - c.

The sum of the correct answers and the wrong answers gives the total number of questions in the quiz.

Thus, the total number of questions in the quiz is given by 15 - c + c = 15.

Therefore, there are 15 questions in the quiz.
