Answers

Answer:

30% are children.

Step-by-step explanation:

Females = 30%

Males = 40%

Therefore, children = 100% (total) - 30% + 40%

100 - 70

30%

QUESTION:

in a city 30 °/• are female and 40°/. are males . what are remaining children?

SOLUTION:

Given,

▶️ percentage of females = 30%

▶️ percentage of males = 40%

▶️ let the percentage of children be x.

Now,

▶️ x = 100% (total population) - 30% + 40%

▶️ x = 100% - 70%

▶️ x = 30% (Children population)

ANSWER:

The population % of children in a city is 30%.

Which graph shows a line with a slope 3/2?

Answers

Answer:

C I think, im not sure but sorry if im wrong

Step-by-step explanation:

Answer:

Graph B.

Step-by-step explanation:

Graph A. is too low and graph C. is too steep.

Also we know that 3/2 is equal to 1.5. This means that it will be a little more than y = x. So if we look at point (2,2), the line is not at that point, but the line is a little higher.

The question I need answered is what is the setting of this story and give specific details from the story. Thank you Which of the following describes one of the main obstacles Schwermer's lifestyle presents?Part of that philosophy requires her to put a lot of faith in the unknown. Other than the small notebook she uses to keep track of her scheduled speaking engagements and housing arrangements, most of her plans are left to fate. I see a lot of miracles in my daily life. For example, in the beginning I found food. I thought about things and then I found them in the street or people came to bring them to me, she explains. I think these miracles happen because of our thoughts. When seasons change, she gives away whatever clothing she has and waits for new items to come along. Most are given by hosts and friends she meets along the way. The road wasnt always easy. With two adult children and three grandchildren, Schwermer admits her family wasnt exactly on board when she pitched the idea. She now sees them only a few times per year, but says they eventually warmed up to her come-and-go lifestyle. Now theyre proud of what Im doing. Its enough for us, she says. Although she never had plans to go public with her life, after a German book publisher pushed her to put pen to paper, Schwermer relented. The latest of three books on her journey, Seeing Miracles In Life Without Money, will be released this summer in Germany. As with its predecessors, all her royalties4 will go to the various charitable groups she supports. Now, more and more young people want to change something in their lives and often they dont know what they can change, she says. I changed something in my life. Despite the legion of fans that have followed her for years, Schwermer has met her fair share of critics. After a trainwreck appearance on Italian talk show RAI TV, she stopped doing television interviews (in one taping, a host actually rifled through her suitcase).More often than not, however, its her friends who become frustrated with her come-and-go lifestyle. Shes turned down many invitations to extend her visits, including offers to stay permanently. There are so many people who are lonely and they like to have friends at their side, she says. But I say no because I cant. I feel that I must go.
