What is the diameter of the smallest circle that would enclose 2,000 pennies?
OlgaM077 [116]

Answer: 84.9

Step-by-step explanation:

Model's equation: y=1.11x^2

Since y = 2000

y = 1.11x^2

2000 = 1.11x^2

x^2 = 2000/1.11

x^2 = 1801.8

x = 42.45

Diameter of the smallest circle will be:

= 2x

= 2 × 42.45

= 84.9

Flura [38]

Answer:

Step-by-step explanation:

Dear Mrs.Rappa,

I don't know much about this but i do know that saving accounts are risky and she should just set up a checking. Because it's proven that you'll take the risk of losing value in your money. And you take a risk, but to help you more i need to know about what the 5% 7 means. if i do know what it's means, but the 5% is good, it's compound interest which means you get more money on that interest It grows, but as far as the 7 goes, IDK. but the saving %"s are good like yay money, but she takes the risks. So why the risk is there is because of the stock market, and also because the bank takes other clients money for them to pay other client's. So a risk in 7yrs.  

                                                       Sincerely,

                                                           First name Last name Here

  1.75xx = 42.00 . . . . . subtract 2.90

  xx = 24 . . . . . . . . . divide by 1.75

The number of miles in Nicole's taxi ride was 24.
