<u>Answer</u>

Time taken to paint the fence by Marco  and Jaylyn is 2.72 hours

Heading can be given to this is work per hour

<u>Explanation</u>

Macro 6 hours to paint fence by himself

Therefore his 1 hour work = 1/6

Jaylyn 5 hours to paint the same fence by herself

Therefore 1 hour work of  Jaylyn  = 1/5

Together 1 hour work = 1/6 + 1/5 = 11/30

Therefore time taken to paint the fence together by them = 30/11 = 2.72 hours

Is this thesis OK for my schizophrenia essay? Schizophrenia is a severe mental illness that deeply affects the patient's daily l
sattari [20]
I don't know how many paragraphs your professor needs you to develop, but if your essay consists on just 3 paragraphs (introduction, body and conclusion) your thesis is OK.
Now, if your essay needs to have, lets say 4 or 5 paragraphs (introduction, body 1, body 2, body 3, and conclusion) I'd recommend you to add two more details to your essay. For example,

Schizophrenia is a severe mental illness that deeply affects not only the patient's daily life, but also his family and friends.

paragraph 1 is to develop how schizophrenia affects the patient daily life only. Paragraph 2 is to develop how schizophrenia affects the patient's family and paragraph 3 to develop how it affects his or her family.

Don't forget to put examples, professors love when you put examples.
Good luck, and if you need help, you can ask me.

D is wrong. It’s an exponential function so every year the number of stores it opens grows. Which means there can’t be one number for each year in terms of amount of new stores.
