  • 5250/273 = 14.075
  • 6250/325 = 19.230
  • 7250/377 = 19.230
  • 9250/273 = 19.230
  1.    <u>6250</u>  = <u>  y   </u>

             377        572

    2.  multiply both sides by 572

    3. 572 .  <u>6250</u> = y

                   377

   4. divide known pair

572 x 19.230 = y

   5. solve for y

   6. y = 10999.56

   7. divide y value by 1000

   8. 10.99956

   9. round to the nearest whole #

   10. There are 11 costumers per tower and 11000 costumers in total

3.Maggie drives three times the number of
RUDIKE [14]

Answer:

Step-by-step explanation:

Let the number of hours driven by Maggie be x and that of Alan be y

If Maggie and Alan drive for a total of 32 hours, then;

x+y = 32 ..... 1

Also if Maggie drives three times the number of  hours that Alan drives on their vacation, then x = 3y ...... 2

Substitute eqn 2 into 1;

x+y = 32

3y+y = 32

4y = 32

y = 32/4

y = 8 hours

Since x = 3x

x = 3(8)

x = 24 hours

Hence Maggie drives for 24 hours and Alan drives for 8 hours

aev [14]

Answer:

36 days

Step-by-step explanation:

Cole's watch runs fast. In 1 day, it gains an hour. So in 12 days, it gains 12 hours and is correct again.

We find the multiples of

Multiples of 12:

12, 24, 36, 48, 60, 72, 84

Note that

1 hour = 60 minutes

12 hours= x

Cross Multiply

x = 12 × 60

x = 720 minutes

Julio's watch also runs fast. In 1 day it gains 20 minutes.

Hence, 720 minutes/20

= 36

Therefore, to calculated how many days will their watches next show the correct time together we use LCM method

We find the Multiples of 12 and 36

Multiples of 12:

12, 24, 36, 48, 60

Multiples of 36:

36, 72, 108

Therefore, LCM = 36

The number of days that their watches next show the correct time together is 36 days
