Answer:
(a) k = C + 273.15, F = 1.8(k - 273.15) + 32
(b) k = 296.15
(c) 25 celcius is greater than 300 kelvis.
Step-by-step explanation:
(a) one equation would be to solve for k instead of c, and another related equation could be from kelvin to Farenheit.
C = k - 273.15
C + 273.15 = k
k = C + 273.15
F = 1.8(k - 273.15) + 32
(b) for this one you have to substitute in the previous equation and solve for k.
23 = k - 273.15
k = 23 + 273.15
k = 296.15
(c) you have to convert either kelvins to celcius or celcius to kelvins.
C = k - 273.15
C = 300 - 273.15
C = 26.85
So 25 celcius is greater than 300 kelvis.
Answer:
The second group
Step-by-step explanation:
The first group is 4 apples for 3 friends.
= 4/3. They each got 1 & 1/3 of an apple.
The second group is 6 apples for 4 friends.
= 6/4. They each got 1 & 1/2 of an apple.
1 1/3 < 1 1/2, so friends in the second group get a larger portion of apples
Answer:
B. rotation 90° counterclockwise about the origin.
Step-by-step explanation:
Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.
Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.
In the given question, ∆ABC is mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.
Answer:
B
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( isolate r by dividing both sides by 2π )
C ÷ 2π = r → B
Step-by-step explanation:
perimeter of triangle = s + s + s
perimeter of given triangle = 22 + 17 + 14
= 53 cm
therefore, perimeter of given triangle is <em>53 cm</em>
