Answer:

but about 20. 2 x 10 since there are 30 marbles, so it makes sense to say 30 x 10 to get 300, but since you only have 2 purple, you only get 2 purple out of every 30,  

SO in conclusion, 20 purple marbles.

Answer:

A) 20

if there are 30 marbles than 30 x 10 = 300. so you would do the same with the purple marbles 20 x 10 = 20.

How would each perspective on criminal justice view the use of death penalty as a sanction for first degree murder?
Natali5045456 [20]
First degree murder convictions typically draw the harshest sentences of any crime. As with the elements of the crime and defenses available, sentencing can vary from state to state. [ Possible sentences are outlined in state statutes, with courts deciding, sometimes within strict statutory guidelines, which sentence a convicted murderer will receive based on the facts determined in the case. ]

How did the nobles of Heian feel about the common people of Japan?<br><br>well give brainlest
LUCKY_DIMON [66]

Answer:

During the Nara Period (710-794 CE) the Japanese imperial court was beset by internal conflicts motivated by the aristocracy battling each other for favours and positions and an excessive influence on policy from Buddhist sects whose temples were dotted around the capital. Eventually, the situation resulted in Emperor Kammu (r. 781-806 CE) moving the capital from Nara to (briefly) Nagaokakyo and then to Heiankyo in 794 CE to start afresh and release the government from corruption Kyoto was the centre of a government which consisted of the emperor, his high ministers, a council of state and eight ministries which, with the help of an extensive bureaucracy, ruled over some 7,000,000 people spread over 68 provinces, each ruled by a regional governor and further divided into eight or nine districts. In wider Japan, the lot of the peasantry was not quite so rosy as the aesthetics-preoccupied nobility at court. The vast majority of Japan’s population worked the land, In terms of religion, Buddhism continued its dominance, helped by such noted scholar monks as Kukai (774-835 CE) and Saicho (767-822 CE), who founded the Shingon and Tendai Buddhist sects respectively. They brought from their visits to China new ideas, practices, and texts, notably the Lotus Sutra (Hokke-kyo) which contained the new message that there were many different but equally valid ways to enlightenment. There was also Amida (Amitabha), the Buddha of Pure Land Buddhism, Following a final embassy to the Tang court in 838 CE, there were no longer formal diplomatic relations with China as Japan became somewhat isolationist without any necessity to defend its borders or embark on territorial conquest. However, sporadic trade and cultural exchanges continued with China, as before. Goods imported from China included medicines, worked silk fabrics, ceramics, weapons, armour, and musical instruments, while Japan sent in return pearls, gold dust, amber, The Heian period is noted for its cultural achievements, at least at the imperial court. These include the creation of a Japanese writing (kana) using Chinese characters, mostly phonetically, which permitted the production of the world’s first novel, the Tale of Genji by Murasaki Shikibu (c. 1020 CE), and several noted diaries (nikki) written by court ladies, including The Pillow Book by Sei Shonagon which she completed c. 1002 CE. Other famous works of the period are the Izumi Shikibu Diary
