nordsb [41]

Answer:

\$164.5

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

i=\dfrac{P\cdot r\cdot r}{100}

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5

So the total amount will be,

=\text{Principal}+\text{Interest}

=70+94.5

=\$164.5

Green River State Park has two popular hiking trails: Overlook Trail and High Ridge Trail. On one particular day, 80 hiking grou
Kipish [7]

Answer:

B. Events H and C are dependent and P(H|C) < P(C|H)

Step-by-step explanation:

The ratios of groups with children to hiking groups on the trail are different for the two trails.

P(H|C) = 15/45 = 1/3

P(C|H) = 15/40 = 3/8

1/3 < 3/8 so the comparison of choice B is appropriate.

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.

Complete question:

A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only 1 / 3 of the marbles in the bag are blue. Then yellow marbles are added to the bag until only 1 / 5 of the marbles in the bag are blue. Finally, the number of blue marbles in the bag is doubled. What fraction of the marbles now in the bag are blue?

(A) 1/5

(B) 1/4

(C) 1/3

(D) 2/5

(E) 1/2
