Answer:

Step-by-step explanation:

Multiply $120 (cost of haircut) X .18 (18% in decimal form) to get the tip amt.

120 X .18 = 21.60

Now add $120 (haircut) + 21.60 (tip) together to get the total amt. she paid.

120 + 21.60 = $131.60

Carla gave her stylist $131.60 total

Answer the two questions below
STALIN [3.7K]

Answer:

3: No

4: 25

Step-by-step explanation:

3: It won't because not everyone is the same height and there will be variation in the mean height.

4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.

From the observation deck of a skyscraper, Harper measures a 45^{\circ} ∘ angle of depression to a ship in the harbor below. If
Evgesh-ka [11]

The horizontal distance between the base of the skyscraper to the ship is 1145 feet.

Data;

  • Angle = 45 degree
  • Observation deck (adjacent) = 1145 ft
  • horizontal distance (opposite) = x

<h3>Trigonometric Ratios</h3>

Using trigonometric ratios, we have the value of adjacent and angle, we can easily use tangent of the angle to find the horizontal distance

tan\theta = \frac{opposite}{adjacent}

Substitute the values into the equation and solve

tan45 = \frac{x}{1145}\\ x = 1145tan45\\x = 1145ft

The horizontal distance between the base of the skyscraper to the ship is 1145 feet.

topjm [15]

Answer:

The value of the expression at w=3 is;

17

Explanation:

Given the expression;

5w+2

Then when w=3, the value of the expression is;

\begin{gathered} 5w+2 \\ =5(3)+2 \\ =15+2 \\ =17 \end{gathered}

The value is gotten by replacing/substituting w with 3 in the expression;

Therefore, the value of the expression at w=3 is;
