 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. 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)

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.

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?

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

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

Half life formula cool. I think you got it. • WOAH this looks like a whole other language to me. Good luck, I'm just here for my akorns    • Akorns prize - Post up a killer recipe on the Feb/Mar Food Contest.

The is a Cheese Cake recipe that is setting the standard.  • 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!

• Yikes! I was willing to help, but this interest stuff is too much for me. I'm more of a calculus person rip

you need a calculus for this, this math is easy for me but I can't calculate it in my head • Sorry I need time to calcu.
