A decorative window is made up of a rectangle with semicircles at either end. The ratio of AD to AB is 3:2 and AB is 30 inches.
scZoUnD [109]

Answer: The required ratio will be

84:1034

Step-by-step explanation:

Since we have given that

Ratio of AD to AB is 3:2

Length of AB = 30 inches

So, it becomes

2x=30\\\\x=\frac{30}{2}=15\ inches

So, Length of AD becomes

3x=3\times 15=45\ inches

Now, at either end , there is a semicircle.

Radius of semicircle along AB is given by

\frac{30}{2}=15\ inches

So, Area of semicircle along AB and CD is given by

2\times \frac{\pi r^2}{2}\\\\=\frac{22}{7}\times 15\times 15\\\\=\frac{4950}{7}\ in^2

Radius of semicircle along AD is given by

\frac{45}{2}=22.5\ inches

Area of semicircle along AD and BC is given by

2\times \frac{1}{2}\pi r^2\\\\=\frac{22}{7}\times \frac{45}{2}\times \frac{45}{2}\\\\=\frac{445500}{28}\ in^2

And the combined area of the semicircles is given by

\frac{4950}{7}+\frac{445500}{28}\\\\=\frac{465300}{28}\ in^2

Area of rectangle is given by

Length\times width\\\\=AD\times AB\\\\=45\times 30\\\\=1350\ in^2

Hence, Ratio of the area of the rectangle to the combined area of the semicircles is given by

1350:\frac{465300}{28}\\\\=1350\times 28:465300\\\\=37800:465300\\\\=84:1034

Hence, the required ratio will be

84:1034

1. Ratio between onions and tomatoes:

There are 3 onions and 4 carrots.

Therefore, required ratio is 3:4


2. Ratio between  tomatoes to cups of chicken stock:

There are 6 tomatoes and 5 cups of chicken stock.

Hence, the required ratio is 6:5.


3. Sticks of butter to bananas:

There are 1 stick of butter and 2 bananas.

So, the required ratio is 1 to 2.


4.  Teaspoons of salt to teaspoons of black pepper:

There are 2 teaspoons of salt and 1 teaspoon of black pepper.

Please refer attached figure.


5. Let's calculate the ratio of cups of chocolate chips to tomatoes.

There are 3 cups of chocolate chips and 6 tomatoes.

Hence, the required ratio is 3:6 and on simplifying, 1:2.

The image below shows the graph of a sound recorded on an oscilloscope. What are the period and the amplitude? (Each unit on the
Serhud [2]
Remember that the period of a sinusoidal function <span>is the vertical distance between the t-axis and one of the extreme points.</span> From the graph we can infer that the period of the function is 4.5.

Also, the amplitude is<span> the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.

We can conclude that the correct answer is: 0.05 seconds; 4.5
