Answer: 3 hours and 20 minutes

Step-by-step explanation:

First , you convert your fraction to a decimal.

6/5 = 1.2

Second , you subtract 4 minus 1.2 to see how much of the work shift does she have left ( since 1.2 hours is what she worked).

4 - 1.2 =  2.8 = 2 hours and 80 minutes (60 minutes is an hour) = 3 hours and 20 minutes

slamgirl [31]

There are 400 balcony seats in the concert hall.

<u>Step-by-step explanation</u>:

Step 1 :

  • The number of lower seats = 450 seats

Total seats = Lower seats + balcony seats

Step 2 :

  • Tickets sold = 170 tickets
  • Total tickets = x

Tickets sold = 1/5 of total tickets.

⇒ 170 = (1/5)x

⇒ x = 5\times170

⇒ x = 850 tickets

∴ Total seats in the concert hall is 850.

Step 3 :

Total seats = 450 + balcony seats

850 - 450 = balcony seats

∴ balcony seats = 400

a television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the scre
Grace [21]

Answer: 75\%

Step-by-step explanation:

You know that the ratio of the television's screen is 5:4 . This ratio can be also written as the following fraction:

\frac{5}{4}

The television shows an image with a ratio of 20:12 which can be also written as a fraction:

\frac{20}{12}

Set up the following proportion and solve for "x":

\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16

Now, in order to find the percent of the screen area occupied make the following division:

\% occupied=\frac{12}{16}*100=75\%
