Answer:

  1.24 kg

Step-by-step explanation:

The ratio of weights is ...

  peach : olive = 7 : 1

In ratio units, the difference of weights is 7-1 = 6 and the sum of weights is 7+1 = 8. Then the ratio of the sum of weights to the difference of weights is ...

  sum : difference = 8 : 6 = 4 : 3

That is, the total weight of the peach and olive is 4/3 times their difference of 0.930 kg:

  total weight = (4/3)·0.93 kg = 1.24 kg

The length is 12 cm more than its width . Find the area of the rectangle if it's perimeter is 100 cm
DaniilM [7]
Let's say the width is (x) and the width is (x+12). The formula for a perimeter of a rectangle equals 2w + 2l, which would then for this problem be 100=2(x) + 2(x+12) which would distribute as 2x + 2x + 12 which equals 4x+12. When you subtract twelve from 100 you get 88=4x. Divide 88 by 4 and you get x=22. This then would mean the width is 22 and the length is 34. The formula for an area of a rectangle is w*l. Plug in the numbers that you figure out from the area formula and you get 22x34=748
