The angle of elevation from the hiker to the park ranger is the same as the angle of depression from the ranger to the hiker, 29°.

The tangent function of an angle is the ratio of the opposite side (500') to the adjacent side (x) in the right triangle shown. That is
tan(29°) = 500' / x

Multiplying the equation by x/tan(29°) gives
x = 500' / tan(29°)
x ≈ 500' / 0.5543
x ≈ 902 ft

Write the multiplicative inverse of a) -13/19

irga5000 [103]

Answer:

$- \frac{19}{13}$

Step-by-step explanation:

$the \: multiplicative \: inverse \: of \: \\ - \frac{13}{19} = - \frac{19}{13}$

Product of a number and its multiplicative inverse should be equal to 1.

So,

$\bigg ( - \frac{13}{19} \bigg) \bigg ( - \frac{19}{13} \bigg)$

$= \frac{13}{19}\times \frac{19}{13}$

$=1$

In order to win a quiz contest, olga must score more than 400 points. She earns 12 points for each right answer, and loses 4 poi

Ket [755]

The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is: $3r-w>100$

Explanation

Number of right answers is $r$ and number of wrong answers is $w$

Olga earns 12 points for each right answer and loses 4 points for each wrong answer.

So, total points earned for $r$ right answers $=12r$

and total points lost for $w$ wrong answers $=4w$

That means, her score will be: $(12r-4w)$ points.

In order to win the quiz contest, Olga must score more than 400 points. So, the inequality will be.......

$12r-4w>400\\ \\4(3r-w)>400\\ \\ 3r-w>100$
