Answer: 35 minutes

Step-by-step explanation:

For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:

= (1320 - 1040) / (9 - 2)

= 280/7

= 40 gallons per minute

Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:

= 1320 gallons + (40 × 2)

= 1320 gallons + 80 gallons

= 1400 gallons

The time taken for the pool to be completely drained will be:

= Total water in pool / Gallons drained per minute

= 1400 / 40

= 35 minutes

Answer:

Hope this helps ^w^

Step-by-step explanation:

Jews  or Jewish people are an ethnoreligious group and Hebrews of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, as Judaism is the ethnic religion of the Jewish people, while its observance varies from strict observance to complete nonobservance. This is amazing religion, how everything is in place in a neat way. the worldwide Jewish population reached a peak of 16.7 million, representing around 0.7 percent of the world population at that time, which is a ton. defines itself as a Jewish and democratic state in the Basic Laws, Human Dignity and Liberty in particular, which is based on the Declaration of Independence. Israel's Law of Return grants the right of citizenship to Jews who have expressed their desire to settle in Israel. Despite their  percentage of the world's population, Jews have significantly influenced and contributed to human progress in many fields, both historically and in modern times, including philosophy, ethics, literature, politics, and cinema, medicine, and science and technology, founded Early Christianity and had a profound influence on Islam. Jews have also played a significant role in the development of Western Civilization. If you thought that was crazy watch until you hear the English word "Jew" continues Middle English '. These terms were loaned via the Old French ', which itself. In my opinion, I enjoy learning about different parts of the world. And as myself, I feel like we all should be equal no matter what race are are.

An angle measures 88° more than the measure of a complementary angle. what is the measure of each angle?
aleksandrvk [35]
Let one angle be x
Let second angle be 88+x
Sum of two complementary angles = 90°
x+ 88+ x = 90°
2x + 88 = 90
2x  = 90 - 88 = 2
x = 2/2 = 1

First angle = x = 1°
Second angle = 88 + x = 88+1 = 89°
