A bag contains purple marbles and blue marbles, 65 in total. The number of purple marbles is 5 more than 3 times the number of b

Marianna [84]

Lets say there are x blue marbles.

Purple marbles = 5 + 3x
Blue marbles = x
Total = 65

5 + 3x + x = 65
5 + 4x = 65
4x = 65 - 5 = 60
x = 60/4 = 15

Blue marbles = 15

65 - 15 = 50

There are 50 purple marbles.

The figures below are similar. What are a) the ratio of the perimeters and b) the ratio of the areas of the larger figure to the

iren [92.7K]

A) ratio of the perimeters is the same as ratio of corresponding sides, so:

$\dfrac{P_1}{P_2}=k=\dfrac{22}{14}=\dfrac{11}{7}\approx1,57$

b) ratio of the areas is equal to k² so:

$\dfrac{A_1}{A_2}=k^2=\left(\dfrac{11}{7}\right)^2=\dfrac{121}{49}\approx2,47$
