V = 20√(273 + t )
when v = 329
∴ 329 = 20 √(273 + t )
∴ √(273 + t ) = 329/20 = 16.45
273 + t = 16.45² = 270.6025
∴ t = -2.3975 ≈ -2 (<span> Rounded to the nearest degree )

Answer:
2 ( m + 2 m) = 36 is the required linear equation
Length of the rectangle is 12 ft and width = 6 ft
Step-by-step explanation:
Let the width of the rectangle = m ft.
So, the length of the rectangle = 2m ft.
Perimeter of rectangle = 36 ft
Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)
⇒2 ( m + 2m) = 36
or, 2 x 3m = 36
⇒ 6m = 36 , or m = 36/6
⇒ m =6 ft
So, the Width of the rectangle; = m = 6 ft
and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.
This is a cubic binomial.
Answer:
(-2.5, - 9)
Step-by-step explanation:
Using the Midpoint theorem, we have
x=(3-8)/2=-5/2=-2.5
y=(-10-8)/2=-18/2=-9
