The arc length, radius and the included angle are related as
where
is in radians.
The radius
is given by

Correct choice is (B).
(1) Snow fall in last week =
inches
Snow fall in today=
inches
Let us first change mixed fraction to improper fraction.

Now, make the denominators same.
, 
Now, find the difference between 14/4 and 23/4.
So, compared to last week
more inches of snow fell today.
(2) Given three times a number, minus nine, equals six times six, divided by four.
Let a number be X.
3X – 9 = 6 × 6/4
(3) To solve the equation:
3X – 9 = 6 × 6/4
3X – 9 = 36/4
3X – 9 = 9
3X = 18
X = 6
h(t) = -16t^2 + vt + 5
h(3) = 131 ft
h(3) = -16(3)^2 + 3v + 5 = 131
3v = 270
v = 90 ft/s
The area of the door is 16ft (4x4) and the window is 900 (30x30) then do 900/16= 56.25 I hope I'm right!
16
x * 3 = 48
so divide 48 by 3
which is 16 so x = 16
