Tim installs 50 square feet on his floor in 45 minutes. At this rate, how long does it take him to install 495 square feet?
Katena32 [7]

Answer:

445.5 minutes

or 7 hours 25 minutes 30 seconds

Step-by-step explanation:

We can use ratio's to solve

50 ft^2           495 ft^2

--------------  = ------------

45 minutes    x minutes

Using cross products

50x = 45*495

50x=22275

Divide each side by 50

50x/50 = 22275/50

x =445.5

445.5 minutes

If we want to convert to hours and minutes, divide by 60

7 hours is 420 minutes

445.5 -420 = 25.5

7 hours 25 minutes

.5 minutes is 30 seconds

7 hours 25 minutes 30 seconds

What should be add to 7 3/5 to get 18
g100num [7]

Answer:

10\frac{2}{5}

Step-by-step explanation:

7\frac{3}{5}  +  x  = 18\\

transformation : 7\frac{3}{5} = \frac{(5*7) + 3}{5}  = \frac{38}{5}

\frac{38}{5}  +  x = 18\\\\x = 18 - \frac{38}{5} = \frac{(5*18) - 38}{5} = \frac{52}{5}

\frac{52}{5} = 10\frac{2}{5}
