What form of measurement do we convert it to?
The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:
T(K) = T(°C) + 273.15;
So, T(K) = -25 + 273.15;
T(K) = 248.15;
The correct answer is a.
If you note that a square can be circumscribed by a circle (circumscribed is when the object is drawn in...right?) this makes things handy.
Draw a circle with the compass, for the diameter = side length of the square.
Drawing the circle ensures that the side lengths will all be congruent.
Now take your straightedge, and draw 4 sides, 2 sides parallel to each other on 2 outer sides of the circle, and 2 on the top, also parallel, BUT also perpendicular to the other 2 lines. You have a square
First, set up the equation using the point-slope formula (y-y1)=m(x-x1).
y1=-4 x1=-3 m=-7/2
(y+4)=-7/2(x+3)
Second, distribute -7/2.
(y+4)=(-7/2)x - 21/2
Third, subtract 4 from both sides.
(y+4)=(-7/2)x - 21/2
-4 -4
______________
y=(-7/2)x - 29/2
Answer:
length=70cm
width=7cm
Step-by-step explanation:
total ratio=10 + 1
=11
length(2)=10/11 x 154 cm
=10 x 14cm
=140cm
one length is 140 cm/2=70cm
width(2)=1/11 x 154cm
=14cm
one width is 14cm/2=7cm
