Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
Answer: Rounded: 350 miles/inch
Exactly 352 miles per inch.
Step-by-step explanation: Divide the miles by the inches to find miles per inch.
880/2.5 = 352.
It would make sense to round that to say the scale is 350 miles per inch.
One inch represents 350 miles
Answer:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

The correct option is C.
Answer:
If the sphere has a radius of 4, you can use the equation: V=4/3(pi)(r)^3
Step-by-step explanation:
V=4/3(pi)(r)^3
V=4/3(pi)(4)^3
