A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only
STALIN [3.7K]

(C) \frac{1}{3} fraction of the marbles now in the bag is blue.

<h3>What is a fraction?</h3>
  • A fraction is a portion of a whole or, more broadly, any number of equal parts.
  • In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters.
  • A common, vulgar, or simple fraction that consists of a numerator above a line and a non-zero denominator below that line.
  • Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals.

To find what fraction of the marbles now in the bag is blue:

  • Important information is that immediately before the last step blue marbles formed \frac{1}{5} from the marble in the bag.
  • That means that there were x blue and 4x other marbles, for some x.
  • When we double the number of blue marbles, there will be 2x blue and 4x other marbles.
  • Hence, blue marbles now form \frac{1}{3} all marbles in the bag.

Therefore, (C) \frac{1}{3} fraction of the marbles now in the bag is blue.

Find the solutions for w​
baherus [9]
Calculation:

(Length) (width) (height)

(2w+4) (w) (18-w) = 1152

(2w^2+4w) (18-w) = 1152

Distributive property:

36w^2 -2w^3+72w-4w^2 =1152

Remember to use FOIL method:

-2w^3 +32w^2+72w-1152 =0

Like terms:

-2(w^3-16w^2-36w+576) = 0

Factor it by 2:

w^3 -16w^2-36w+576 =0

Simplify:

w^2(w-16)-36(w-16) =0

(w^2-36) (w-16) = 0

w= -6,6,16

Width:

w = 6,16

Since width is 16, then the height should be less than the width (18-16=2)

Length of gift bag: 2(6)+4

=16 inches.

Width of the bag: 6

Height of the bag: 18-6

12 inches.

Answer: 16, 6 and 12 inches.
