Determine the digits of Y from these clues.
Doss [256]

Answer:

Y = 963

Step-by-step explanation:

The digits of Y add to 18.  The first digit is 3 times the third digit.  The second  digit is 2 times the third digit.  Y is a three digit number.​

Let Y a three digit number be: abc

First digit = a , Second digit = b, Third digit = c

Also given,

The digits of Y add to 18. => a+b+c = 18     eq(i)

The first digit is 3 times the third digit. => a = 3c     eq(ii)

The second digit is 2 times the third digit. => b = 2c     eq(iii)

Putting value of a and b in eq(i)

3c + 2c + c = 18

6c = 18

c= 18/6

c = 3

Putting value of c in eq(ii) and eq(iii)

a= 3c => a=3(3) => a= 9

b= 2c => b=2(3) => b = 6

Thus, Y = abc

Y = 963

The length of a rectangle is twice its width.The perimeter of the rectangle is 30cm.Calculate the area of the rectangle.
hammer [34]

Answer:

Step-by-step explanation:

Let width be w.

Length is 2w.

Therefore:

2w + 2w + w + w = 30 cm

6w = 30 cm

w = 5 cm.

Width = 5 cm

Length = 5 * 2 = 10 cm

Area = length * width = 10 * 5 = 50 cm2

Wastewater is filling barrels at the rate of 11 quarts per hour. The recycling facility picks up 120 full barrels on each trip,
givi [52]
120 barrels x 12 quarts per barrel = 1440 total quarts

1440 quarts  /  11 quarts per hour  = 130.91 hours to fill all the barrels

1 day = 24 hours

130.91 hours  /  24 hours  = 5.45 days = 5.5 days
