A hockey bag contains 5 red jerseys, 6 blue jerseys and 7 white jerseys.

ipn [44]

Answer:

7/54

Step-by-step explanation:

A hockey bag contains 5 red jerseys, 6 blue jerseys and 7 white jerseys.

Let the total number of jerseys =

5 red jerseys + 6 blue jerseys 7 white jerseys.

= 18

P(White) = 7/18

P(Blue) = 6/18

Hence, the probability that Jack picks a white then a blue jersey if he puts the first one back.

This is probability with replacement, hence:

7/18 × 6/18

= 7/18 × 1/3

= 7/54

Victoria's spends 5/9 of her money on a flan and two chicken pies each chicken pie cost 1/6 as much as the fly Victoria has $24

Fynjy0 [20]

Answer:

Amount spent by Victoria = $30.

Cost of 1 flan = $22.50

Step-by-step explanation:

Let x be total amount of money that Victoria had before purchasing the flan and chicken pies.

We have been given that Victoria's spends 5/9 of her money on a flan and two chicken pies and Victoria has $24 left. This means that 4/9 of total money is 24.

We can represent this information as:

$\frac{4}{9}x=24$

Let us solve for x.

$x=24*\frac{9}{4}$

$x=6*9=54$

Let us find 5/9 of 54 to figure out the amount spent by Victoria.

$\text{Amount spent by Victoria}=\frac{5}{9}*54$

$\text{Amount spent by Victoria}=5*6=30$

Therefore, Victoria spent an amount of $30.

Let C be cost of one chicken pie and F be cost of one flan.

We have been given that each chicken pie cost 1/6 as much as the flan. We can represent this information in an equation as:

$C=\frac{1}{6}F...(1)$

We are also told that Victoria's spends 5/9 of her money on a flan and two chicken pies.

We can represent this information as:

$2C+F=30...(2)$

Upon substituting C's value in equation (2) we will get,

$2*(\frac{1}{6}F)+F=30$

$(\frac{1}{3})F+F=30$

Now let us have a common denominator.

$(\frac{1}{3})F+\frac{3F}{3}=30$

$(\frac{1+3}{3})F=30$

$(\frac{4}{3})F=30$

$F=30*\frac{3}{4}$

$F=30*0.75$

$F=22.50$

Therefore, the cost of one flan is $22.50.
