She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left
Dovator [93]

Answer: She had left 54% of the money which is $1620.

Step-by-step explanation:

40% of $3000 = $1200

15% of $1200 = $180

$3000 - ($1200 + $180)

$3000 - $1380 = $1620

$1620 is the money she had left.

$1620 is 54% of $3000

She had 54% left of the money.

Hope that helped~!

Question 2

Answer:

<em>The firefighter should extend the ladder at 54° of elevation.</em>

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

<em>Tangent Ratio:</em>

\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}

The woman is trapped at 91 feet up from the ground, and the firetruck is 67 feet away from the building.

The wall, the ground, and the ladder form a right triangle, where θ is the horizontal angle of the ladder.

Being the height of the woman the opposite leg and the distance where the firetruck is parked, the adjacent leg:

\displaystyle \tan\theta=\frac{91}{67}=1.3582

The angle is calculated as the inverse tangent:

\theta=arctan(1.3582)\approx 54^\circ

The firefighter should extend the ladder at 54° of elevation.

Evaluate ƒ(x) when x = -9. <br><br><br>A. No solution <br><br>B. 488 <br><br>C. 12 <br><br>D. 110
kondaur [170]

Answer:

The answer to your question is: 12

Step-by-step explanation:

 You have a function with two conditions,

- the first condition do not consider number nine, because it uses the symbol <, then we can not evaluate nine in this function.

- the second condition considers nine because uses the symbol ≤ which means that nine is considered here, but the function equals 12, so that is the solution.
