Answer:
Anthony has $2.10
Step-by-step explanation:
If Maria has 6 nickels and one has 15 more nickels than Maria, one has a total of 21 nickels. Since Anthony has twice the amount of nickels as One, you would multiply 21 by 2 to get a total of 42. It takes 20 nickels to make a dollar. If you divide 42 by 20 you get 2.1, which is equivaldnt to $2.10
The equivalent is 60 over a hundred
1.4 / 7
multiply by 10 in both up and down
(1.4*10) / (7*10)
14 / 70
divide by 7
(14/7) / (70/7)
2 / 10
divide by 2
(2/2) / (10/2)
1 / 5
It should be 78.54.
Double check that.
Formula: V=πr2h/3
r2 is R squared
1 x14=14 * what times one is one*
2 x7=14
