Answer:
128 seconds
Step-by-step explanation:
The sun subtends an angle rad
Angular velocity equation is
where is angular velocity and t is time.
Earth spins at a rate of :
rad/s
Isolating time (t) from angular velocity equation gives:
Answer:
1221 - 321 = 900
Step-by-step explanation:
Answer:
4 inches
Step-by-step explanation:
A = b x h
A = 36
b = 9
36 = 9 x h
4 = h
height = 4 inches
The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
