an aircraft carrier leads port heading due west at 28 knots. A helicopter is 175 nautical miles from the carrier at an angle of

emmainna [20.7K]

Let’s say it takes time t hours for the interception.
In that time the carrier travels 28t nm west and the helicopter 130t nm.
Now we use the sine rule to find the angle x which lies between the distance 175 and 130t.
sin(x)/28t=sin35/130t. So sin(x)=28sin35/130=14sin35/65=0.1235 and x=7.0964 degrees.
Therefore the helicopter should use a bearing of 35+7.0964=42.0964 degrees north of east or 47.9 degrees east of north approx.

Question 5 of 10

True [87]

Answer:

The median value of the houses is $169,000

Step-by-step explanation:

Since the houses were undervalued by $15,000, add $15,000 to all amounts

154,000 + 15,000 = 169,000

133,000 + 15,000 = 148,000

167,000 + 15,000 = 182,000

145,000 + 15,000 = 160,000

180,000 + 15,000 = 195,000

172,000 + 15,000 = 187,000

149,000 + 15,000 = 164,000

To take the median of the data set, order the numbers from least to greatest

148,000 160,000 164,000 169,000 182,000 187,000 195,000

Eliminate one number from both sides until you reach one number

The number is 169,000

A store manager paid $95 for an item and set the selling price at $116.85. What was the percent markup?

Neporo4naja [7]

We have been given that a store manager paid $95 for an item and set the selling price at $116.85. We are asked to find the percent mark-up.

We will use percent increase formula to solve our given problem.

$\text{Percent increase}=\frac{\text{Final}-\text{Initial}}{\text{Initial}}\times 100\%$

$\text{Percent increase}=\frac{\$116.85-\$95}{\$95}\times 100\%$

$\text{Percent increase}=\frac{\$21.85}{\$95}\times 100\%$

$\text{Percent increase}=0.23\times 100\%$

$\text{Percent increase}=23\%$

Therefore, the mark-up will be 23% and option 'b' is the correct choice.
