Answer:
D
Step-by-step explanation:
If you multiply 3 and 7 you are saying she worked 21 hours when she only worked a total of 10 hours.
A cube has 6 faces. The surface area of a cube is 6 times the area of one face.
SA = 6s^2
SA = 6 * 6cm^2
SA = 6 * 36cm^2
SA = 216cm^2
X^2-11x+28=0
(x-7)(x-4)=0
x-7=0
x=7
x-4=0
x=4
Answer:
Pendulum will swing by an angle 0.666π
Step-by-step explanation:
We have given arc = 
And length of the pendulum l = 150 cm
Length of the pendulum will be equal to radius of the pendulum so r = 150 cm
Arc is given by 
So 

So pendulum will swing by an angle 0.666π
