About how many times would all the pennies ever made lined up circle around the of the earth?
I would say approximatley 671,385,264 pennies is how much it would take to wrap around the Earth once this answer is really wrong! so heres the right answer two ways: first , if a penny is : 19.05 mm (0.750 in) in Diameter and then earth is 40075.02 km at the middle(Circumference) then it would take 1,577,756,692.9 pennies. Think edge to edge! 40 075.02 kilometer = 1 577 756 692.9 inch second, if you were to lay them standing up back to back, then the Thickness:1.55 mm (0.061 in), so it would take 40,075,020,000 pennies! 40 075.02 kilometer = 40 075 020 000 millimeter so i would estimate that the U.S. made about 125 trillion pennies from 1793 to 2008. so you could do it about twice, however most pennies have a life of 22 days before they end up in the trash.
if the earth had twice it’s present radius and twice it’s present mass, what would happen to your weight explain your answer?
i will be twice as heavy
What does twice mean in math?
Generally, "twice" means double. So, twice X is equal to X plus X. Twice four is eight. simmisinghsaini's answer- But however, doesn't it mean to divide when we have to translate algebraic expressions?
Is the diameter of a circle twice the size of the radius?
Yes, the diameter of a circle is twice the length of the radius.

How many dimes is in 2.31 if there are twice as many dimes as pennies?
The X.X1 at the end of the number implies that there could be 1, 11, 21, 31, etc. pennies. Now, we could go through and test the instances. .01 means that there is 1 penny. Therefore, there are 2 dimes to make .31, which does not work. .11 means that there are 11 pennies. Therefore, 22 dimes are required, which make $2.31. This works, so there are 22 dimes.
A stack of nickels and dimes is worth 2.55 find the number of nickels if the number of dimes is 12 less than twice the number of nickels how many nickels are there?

The coins in a cash register total 12.50 and there are only nickels dimes and quarters. There are twice as many dimes as nickels and there are twice as many quarters as dimes. How many many dimes are?
You need to define variables for the different types of coins, write the corresponding equations, then solve them. One equation for each fact. Here are the equations:5N + 10D + 25Q = 1250 D = 2N Q = 2D
Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
If Mia has twice as many quarters as dimes with a total of 3.60 how many of each coin does she have?
12 quarters and 6 dimes 2(.25x) + .10x = 3.60 50x + 10x = 360 60x = 360 x = 6
A coin collection worth 2.15 consists of nickels dimes and quarters If there are 13 coins and twice as many nickels as dimes how many of each are there?
7 quarters 2 dimes 4 nickels
There are twice as many nickels as dimes and five more dimes than quarters The total value is 6.40 How many quarters are there?
Twelve. Here is how: Using cents rather than decimal dollars: 5n + 10d + 25q = 640 Express the numbers of nickels and quarters in terms of the number of dimes: # of nickels = twice the # of dimes ==> n = 2d # of quarters = 5 less than the # of dimes ==> q = d-5 Substitute for n & q in original equation: 5(2d) + 10d + 25(d-5) = 640 45d - 125 = 640 45d = 765 d = 17 ==> 170 = $1.70 n = 34 ==> 170 = $1.70 q = 12 ==> 300 = $3.00 . . . . . . . . . Total = $6.40
