If u varies directly with v, with k = 0.6, what is the value of u when v= 7.8?
o
a
u= 13
o
b. u=0.77
o
c. u=0.468
o
d. u= 4.68

D)  The value of u  is 4.68   when v= 7.8 .

Step-by-step explanation:

Two quantities P and Q  are said to be in proportion if one quantity is always a multiple of the other quantity.

or, P ∝ Q   ⇒   P  = k Q for some arbitrary constant k.

Here, u varies directly with v

⇒   u  = k v

Now, k = 0.6 and v = 7.8

So, u = k v

         = (0.6) x (7.8)  = 4.68

or, u = 4.68

Hence, the value of u when v= 7.8  is 4.68.

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
