Marsha has $2.20 in her piggy bank. she has 5 times as many pennies as nickels. she has 3 more dimes than nickels. she has 3 times as many quarters than nickels. how many nickels does she have?

Step-by-step explanation:

If you set aside the excess dimes, the coins can be grouped as ...

  {1 nickel, 5 pennies, 1 dime, 3 quarters}

The value of this group is $0.95, and the total value of all groups is ...

  $2.20 - 3×0.10 = $1.90

So, the number of groups is ...

  $1.90 / $0.95 = 2

That means Marsha has ...

  2 nickels

The other coins Marsha has are 10 pennies, 5 dimes, and 6 quarters, for a total amount of $0.10 + 0.10 + 0.50 + 1.50 = $2.20.

the answer is 48m^2!

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
