An environmental scientist estimated the number of drops of water in two different jugs. He estimated that the smaller jug contains 407,000,000 drops of water and the larger jug contains 9,360,000,000.000002 drops of water. What is the difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug?

The difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug is 8953000000

Solution:

Given that,

He estimated that the smaller jug contains 407,000,000 drops of water

The larger jug contains 9,360,000,000.000002 drops of water

To find: difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug

Therefore,

Larger jug = 9,360,000,000.000002

Smaller jug = 407,000,000

Difference = larger jug - smaller jug

Difference = 9,360,000,000.000002 - 407,000,000

Difference = 8953000000

Thus the difference is found

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
