455 red roses

Step-by-step explanation:

Given parameters:

Number of roses sold by florist  = 715

Unknown:

Number of red roses she sold  = ?

Solution:

From the problem statement, we know that;

       7 out of every 11 roses were red.

Let us divide the roses sold into group of 11s;

          In 715 we 65 groups of 11;

if;

            7 out of every 11 roses were red;

  In a group of 65, we will have 65 x 7 red roses  = 455 red roses

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
