Answer:

The answer to your question is  x = 7\sqrt{2}  and y = 14\sqrt{3}

Step-by-step explanation:

To find x and y use trigonometric functions

- Find x

To find x use the trigonometric function cosine

       cosine Ф = adjacent side/hypotenuse

- Solve for adjacent side (x)

       x = hypotenuse x cos Ф      

- Substitution

      x = 14\sqrt{2} cos 60

Simplification

      x = 14\sqrt{2} (0.5)

      x = 7\sqrt{2}

- Find y

-Find the length of the opposite side of the small triangle

 Opposite side = sine Ф x hypotenuse

 Opposite side = 14\sqrt{2} x sin 60

Opposte side = 14\sqrt{2} (\sqrt{3}/2)

Opposite side = 7\sqrt{6}

- Find the length of y

 y = Opposite side/sin Ф    

 y = 7\sqrt{6} / \sqrt{2} /2

 y = 14\sqrt{3}

Richard bought a pair of shoes for $37.00, a tie for $22.00, and a new belt for $17.00. If the sales tax is 7.5%, how much sales
nadezda [96]

It seems to me, that if you were to add the price of all three items together, then multiply by 7.5%, you'd have the answer.  Remember that 7.5% = .075 ... in other words, that is the number you would multiply the sum of the items by.  Does that help?

Find the missing number.
DENIUS [597]

Answer:

20%

Step-by-step explanation:

In the graph, there is a cycle of increasing and decreasing. First, the original circle increases by 25% into the new, larger circle. Then, the circle does back to its original size. So, to solve we can assign a value to the smaller circle, increase it by 25%, and then find what percentage brings this back to the original value.

It is easiest to assign the value of 100 because it is easy to work with. So, let's say the smaller circle is 100; this increased by 25% is 125. The next step is to find what percentage of 125 brings us back to 100. There are multiple ways to do this such as guess and check or proportions/fractions. Either way, the correct percentage is 20%. If you decrease 125 by 20% you get the correct value of 100. This means that the missing number must be 20%.

A dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours. At this constant​ rate, how long does i
Novosadov [1.4K]

Answer:

\frac{4}{5} hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths ​-mile state fair​ race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

We will equate both speeds as:

\frac{1\frac{3}{10}}{x}=\frac{3\frac{1}{4}}{2}

\frac{\frac{13}{10}}{x}=\frac{\frac{13}{4}}{2}

\frac{13}{10\cdot x}=\frac{13}{4\cdot 2}

Cross multiply:

13\cdot 10\cdot x=13\cdot 4\cdot 2

10\cdot x=4\cdot 2

\frac{10\cdot x}{10}=\frac{4\cdot 2}{10}

Therefore, it will take \frac{4}{5} hour to complete 1\frac{3}{10} mile state fair​ race.
