<span>Since the number of quarters, dimes, and nickels is going to be the same for each, we can assign x as the quantity of each coin and place it by its monetary value: .25x + .10x + .05x = 4.00 This then simplifies to: .40x = 4.00 4 divided by .4 gives x a value of 10, so there would be 10 quarters, 10 dimes, and 10 nickels.</span>

What is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet?
mafiozo [28]

Answer:

The height of the tank is 0.5 yards.

Step-by-step explanation:

To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:

1 foot = 0.3333 yards

R = Diameter / 2

R = 120/2 = 60

3.14 x 60 ^ 2 x H = 1,884

3.14 x 3,600 x H = 1,884

3.14 x 1,200 x H = 1,884

3.768 x H = 1.884

H = 1,884 / 3,768

H = 0.5

Therefore, the height of the tank is 0.5 yards.

The length of a side of a square field is 48m.Find the cost of ploughing the field at the rate of rs 25/m and cost of fencing th
brilliants [131]

Answer: rs 4800, rs 3456

Step-by-step explanation:j

given data:

length of a sid = 48m

cost of ploughing the field = rs 25/m

cost of fencing the field = rs 18/m

solution:

we know a square has four equal sides. so total length of the field is

= m ( 48 + 48 +48 + 48 )

= 192m

cost of ploughing the field

= 192m * rs 25

= rs 4800

cos of fencing the field

= 192m * rs 18

= rs 3456
