A ship is 1.4° off course. If the ship is traveling at 14.0 miles per hour, how far off course will it be after 2 hours?
sesenic [268]

Answer:

  about 0.7 miles

Step-by-step explanation:

When you draw a diagram of the problem, you see that the shortest distance back to the course is the distance traveled times the sine of the angle:

  distance off course = (14 mi/h)×(2 h)×sin(1.4°) ≈ 0.684 mi

The ship is about 0.7 miles from its intended course.

A share of stock in the Lofty Cheese Company is quoted at 25 1/4. Suppose you hold 30 shares of that stock, which you bought at
sergij07 [2.7K]
Number of stocks held = 30
Price at which each shares of Lofty Cheese Company bought = 20 1/4
                                                                                                 = (81/4) dollars
Price at which each shares of Lofty Cheese Company sold = 25 1/4
                                                                                             = (101/4) dollars
Amount of profit made per share of Lofty Cheese Company = [(101/4 - (81/4)] dollars
                                                                                                 = (20/4) dollars
                                                                                                 = 5 dollars
Amount of profit made for 30 shares of Lofty Cheese Company = (30 * 5) dollars
                                                                                                       = 150 dollars.
So you will make a profit of $150.The correct option in regards to the question given is option "C".

A manager is comparing the cost of buying ball caps with the team emblem from two different companies. Company X charges a $50 f
Nady [450]

Answer:

10 ball caps

Step-by-step explanation:

In this question, we are trying to know the number of caps the manger would buy that would equate the cost at both companies.

How do we get this?

Since we do not know the number of caps, let’s assign a variable. Let the number of caps that is required be x. Let’s now make some costings in terms of x. We proceed;

Company X charges $50 fee plus $7 per cap. Total amount company X will charge on x caps will be; $50 + $7(x) = $50 + $7x

Company Y will charge $30 plus $9 per cap. Total amount company Y will charge on x caps will be $30 + $9(x) = $30 + $9x

We are trying to look at the value of x that will make both costs equal. What we do is to equate both costs.

30 + 9x = 50 + 7x

We simply by taking like terms to the same sides

9x-7x = 50-30

2x = 20

x = 20/2 = 10

X = 10

So what this means is that manger has to buy 10 caps to have the same cost in both companies

Mr. Smith has 5 1/2 acres of land for sale. He divided the land into 1/2 acre lots. How many lots are for sale?
r-ruslan [8.4K]

Answer:

11 lots are for sale.

Step-by-step explanation:

This is as simple as:

5\frac{1}{2} /\frac{1}{2}

Since Mr. Smith divided the land into 1/2 acre lots, you'd just divide it by the amount he has.
