Can someone help me with my math homework?

  • 1. Oahu has a total land area of 727 square miles. What percentage of Oahu is Maui knowing that Maui is 1546 km^2 total land area.

    1 square mile=2.59 square miles. 1546/2.59=596.9139 727/596.9139=1.2179


    2. In a pineapple, assuming it weighs 905g, the grams of sugar typically amount for 10% of its weight. A pineapple cut in chunk fills 4.5 cups. how many grams of sugar there is in one cup of pineapple chunk?

    1 cup= 128 x 4.5= 576 576/90.5=6.364


    3. A team won 80% of their payoff games, knowing that there were 10 games. In addition, they won 12 out of 15 of their regular season games. What is their total winning percentage?

    20/25 x 100=80%


    4. Let's assume that after a recent Hurricane, storm shutter production in Hawaii would be increased. If 4,000 storm shutters were sold in 2019, and demand increases by 45% every three years, how many were to be sold in 2022? 2030? 2050?

    2022: 4000 x 1.45= 5800 2030: 17683.025 2050: ? I think the formula to get to 2050 is 4000(1 +0.45)t but idk what t is.


    5. The price of coffee is increasing by 1 cents per ounce per week as a result of a shortage. If the price if $6.50 per pound today, what will it cost for a 12oz bag in 4 months?

    4 months= 17.381 weeks 6.50+17.381=28.881


    6. Suppose in one month currency 1 lost 5.3% of its value against currency 2. At this rate, approximately how long will it take for currency 1 to loose half of its value against currency 2?

    Thalf= 70/P 70/5.3= 13.2 months


    7. In 2000, the population of Littletown was 17,000. Use the given doubling time to predict the population in 2060. Assume a doubling time of 32 years.

    new value= initial value x 2t/tdouble (I don't know how to solve this but the answer is 62,400. Could someone show me how they would get that number)


    Thank you

  • Mostly the problems have similar answer. Hawaii is where to be. :dancer:

    Finding the linear unit of yearly population increase I get 63,750.

    Using Compound formula I get 62,356 rounding off to three numerals 62,400.

    A = P(1 + r/n)nt

    Think in units of 32 years. A(amount), P(Principle), r/n(Rate), nt(time)

    P = 17000

    r/n = 100% increase every 32 years. aka doubles every 32 years.

    nt = units of 32 years 60/32 = 1.875


    A = 17000(1+1)^1.875

    A = 17000 x 2^1.875

    A = 62,356.27


  • 4 and 6 have same type of dynamic changes as question 7.

    A = P(1 + r/n)nt

    Think in units of 3 years. A(amount), P(Principle), r/n(Rate), nt(time)

    P = 4000 shutters

    r/n = 45% increase every 3 years.

    nt = units of 3 year

    2022 - 2019 = 3, 2030 - 2019 = 11, 2050 - 2019 = 31

    nt 2022 = 1, nt 2030 = 3.67, nt 2050 = 10.3

    A2022 = 5800, A2030 = 15,640, A2050 = 184,000

    Half life formula cool. I think you got it.

  • Oh, I understand you. I had problems with math at school so I went to a neighbor who helped me with it. At school I had a problem only with mathematics, so when I went to university I chose a profession not related to mathematics. It wasn't difficult for me at university, so I decided to get a job. Now I spend a looot of time at work. It's hard to combine work and study but I succeed!

  • Sorry I need time to calcu.
