Answer:  No

Step-by-step explanation:

We know that the equation for direct proportion between two quantities x ( independent variable) and y (dependent variable) is given by :-

y=kx , where k is the proportionality constant.

if the relationship between the cost (dependent variable ) and the number of pizzas (independent variable ) is proportional, then k in the above equation remains constant for each row.

Let k=\dfrac{\text{Cost }}{\text{Number of pizzas}}

1) k=\dfrac{12.50}{1}=12.50

2)  k=\dfrac{20}{2}=10

But 10≠12.50, thus the value for k is not fixed.

Hence, the relationship between the cost and the number of pizzas is not proportional.

Answer:

Teks narasi sendiri merupakan teks yang menceritakan kisah atau cerita tentang sesuatu. Jadi, kesimpulannya teks cerita fantasi adalah teks narasi yang mengisahkan imajinasi.

Ciri-Ciri Cerita Fantasi

Teks cerita fantasi memiliki beberapa ciri yang membedakannya dari teks narasi lainnya, yaitu:

Cerita fantasi mengandung keajaiban, keanehan, atau kemisteriusan. Juga berisi hal-hal gaib dan misterius yang tidak ditemui dalam dunia nyata.

Cerita fantasi adalah cerita fiksi yang bergenre fantasi, atau dunia imajinatif ciptaan penulis. Pada cerita fantasi, hal yang tidak mungkin dijadikan seolah-olah biasa.

Tokoh dan latar adalah ciptaan penulis dan tidak ada di dunia nyata. Atau modifikasi dari dunia nyata.

Cerita fantasi memiliki tema magic (keajaiban) seperti sihir, supernatural, atau futuristik.

Ide cerita terbuka mengikuti daya khayalan penulis.

Rangkaian peristiwa cerita fantasi memakai latar yang tidak terbatas dimensi ruang dan waktu. Misalnya tokoh utama bisa berada di beberapa waktu dan tempat dalam satu cerita.

Tokoh di dalam cerita fantasi biasanya diberi watak dan ciri yang unik, serta jarang ada dalam kehidupan sehari-hari. Maksudnya, tokoh memiliki kesaktian dan kekuatan tertentu, atau mengalami peristiwa misterius yang unik dan tidak ada di kehidupan biasa.

Cerita fantasi bersifat fiktif. Memang bisa saja terinspirasi dari latar atau objek nyata, namun tetap dibumbui imajinasi dan fantasi.

Bahasa yang digunakan variatif, ekspresif, dan menggunakan ragam percakapan yang bukan bahasa formal.

Jenis Cerita Fantasi

Jenis cerita fantasi dapat dibagi menjadi dua kategori yaitu berdasarkan kesesuaiannya dengan kehidupan nyata dan berdasarkan latar cerita.

Answer:

24.3

Step-by-step explanation:

because each side is the same. one has 12 inch and the other is 9. So you subtract 9 from 12 and get 3. Then you have to find out what the other mesurment is for the bigger shape, which is 2.7 because 32/12=2.66666, so u round and get 2.7 . so theen you multiply 9 and 2.7 and get 24.3!
