Answer:
It would take Beth twelve minutes to wash the car herself
Step-by-step explanation:
If they do it together in 6 minutes.
& Katy can do it in 18 minutes alone

Answer:The surface area of the cube is 100 cm.
Step-by-step explanation:
So since a cube has six faces and all of its lengths are equal. we could use the equation.
10^2 *6= 100 *6= 600
The given expression is:
(x/2) + 5
Let's look at each terms separately:
x/2 means that you you're getting half the value of a number
+5 means that you are adding 5
Combining both, you can conclude that you are adding 5 to half a certain given number.
Comparing this with the choices, the correct choice would be:
C. five more than half a number.
Answer:
a) t₀ = 1.73205 s
b) 1.0 C
Step-by-step explanation:
(A)
The time dilation (t) observed by an observer at rest relative to the time (t₀) measured by observer in motion is;
time measured by captain
⇒ 
V = 0.5 c
⇒ t₀ = 1.73205 s
(B)
Speed of the light never exceeds by its real value. The speed of the light in any frame of reference is constant.
∵ It will be "1.0C" or just "C"
