Answer:

The mean of the tap water boiling point is about 2 degrees Celsius less than the mean of the salt water temperature.

Step-by-step explanation:

Boiling point is the temperature at which a liquid boils or changes from liquid form to gaseous form. Water has a boiling point of 100 degrees Celsius.

Boiling point of water depends on atmospheric pressure which changes according to the height above sea level of a place.

Boiling point can also change depending on the purity of water.Water that has impurities such as salt will have a slightly higher boiling temperature.

The mean of the tap water boiling point is about 2 degrees Celsius less than the mean of the salt water temperature.

The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. What was the original length of
aleksley [76]

The Original length of each side of square was 14.25 inches.

Step-by-step explanation:

Perimeter of a square is given by:

Perimeter = 4 * side

Let x be the original length of each side of square

So

decreasing 2 inch will mean

x-2

Perimeter of square after reducing 2 inches from each side

4(x-2) = 49\\4x-8 = 49\\4x = 49+8\\4x = 57\\\frac{4x}{4} = \frac{57}{4}\\x = 14.25

So,

The Original length of each side of square was 14.25 inches.

PLEASE HELP<br> A) 8<br> C) 1<br> B) 6<br> D) 7<br><br> What is the value of x?
SVEN [57.7K]

Answer: 7

Step-by-step explanation:

As tangents drawn from a common external point to a circle are congruent,

  • 8x - 7 = 6x + 7
  • 2x - 7 = 7 [subtract 2x from both sides]
  • 2x = 14 [add 7 to both sides]
  • x = 7 [divide both sides by 2]
