tatyana61 [14]

Given

John had a roll containing of wrapping paper  

=24\tfrac{2}{3}

First, he must cut off 5/6 foot because it was torn.

He wants to divide it into 11 pieces.

To proof

As given in question

John had a roll containing of wrapping paper

=24\tfrac{2}{3}

=\frac{74}{3}    ( solving the mixed fraction form)

 First, though, he must cut off 5/6 foot

than we get

= \frac{74}{3} - \frac{5}{6}

Taking the L.C.M of 3 and 6 is 6

=\frac{148-5}{6}

=\frac{143}{6}

=23.83 feet (approx)

He wants to divide it into 11 piece

length of the each piece

=\frac{23.83}{11}

length of the each pieces be 2.16 feet ( approx)

Hence proved

marin [14]

Answer:

Robbie pay in twelve months $1080 .

$92.47 more Robbie pay and 9.36 %(Approx) Robbie pay.

Step-by-step explanation:

As given

Robbie Morse has a $47,500 insurance policy.

The annual premium is $987.53.

Robbie pays $90.00 monthly.

First find out the Robbie pay in twelve months .

Robbie pay in twelve months = 12 × 90

                                                  = $ 1080

Second find out how much more does Robbie pay .

Robbie pay extra = Robbie pay in twelve months -  annual premium

                             = $ 1080 - $987.53

                             = $92.47

Therefore the $92.47 more Robbie pay .

Third find out the what percentage does Robbie pay .

 Formula

Percentage = \frac{Robbies\ pay\ more\times 100}{annual\ premium}

Robbies pay more = $92.47

Annual premium = $987.53

Put in the above

Percentage = \frac{92.47\times 100}{987.53}

Percentage = \frac{9247}{987.53}

Percentage = 9.36 % (Approx)

9.36 %(Approx) Robbie pay.
