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.
Since both 2 and 5 are prime numbers, there are no multiples for the fraction 2/5.
Answer:
C: a reflection across the y axis rotated 180 degrees
Step-by-step explanation:
The y axis is a vertical line, the same like that the trapezoid is flipped across
The trapezoid is rotated 180 degrees across the y axis
The formula of the Lateral Area of a cylinder is:
Lateral Area = 2
rh
=2
(12)(60) (altitude is 5×radius)
(5×12=60)
=4523.9 mm² ≈ 4524 m²
Answer is
D. 4524 m²
