Diane, age 14, wants to purchase "Run Fast, Jump High" sneakers for $100. Her parents tell her she must look for a summer job and save her money for her sneakers. She decides to baby-sit for some neighbors. She charges $5 dollars per hour and usually has 12 hours of work per week. She's decided to save half of what she earns and spend the rest on movies, clothes, etc. Will she have enough at the end of five weeks to buy her sneakers? Why or why not?

Yes Diane will have enough money to buy sneakers because she will have 420 dollars in total. I got that by multiplying 5x12, which gives me 60. And than I multiply 60 by 7(days in a week). And i divided 420 by 2 and got 210.

She will still have 210 dollars for etc part. Hope this helps! If you have anymore questions please ask me. I am here to help you and others. Stay safe and have a great day!

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
