The answer to -7 +11 -6 + 8 =6
6 pairs + 11 pairs = 17 pairs
They started with 17 pairs.
Hope this helps.
3/5g-(1/3)=(-10/3)
move the 1/3 over
3/5g=(-10/3)+(1/3) (notice the + sign)
3/5g= (-9/3)
3/5g=(-3)
move the 3/5 over (divide)
g= (-3/(3/5))
g= (-3x5/3)
g= -15/3
g= -5
Answer:
the equation for v is v = 250 km/h * [1- e^(-kt) ]
Step-by-step explanation:
since the acceleration "a" is the rate of change of velocity "v" with respect to the time "t", we have
a= dv/dt= k*(250 - v)
thus
dv / (250 - v) = k*dt
if we proceed then to the indefinite integration in both sides
∫dv / (250 - v) = ∫k*dt
- ln (250-v) = k*t +C , where C= constant
if we know that at t=0 , v(t=0)=0 , then
- ln (250-0) = k*0 +C
- ln 250 = C
replacing C in the original equation:
- ln (250-v) = k*t - ln 250
ln [(250-v)/250] = -k*t
v = 250 km/h * [1- e^(-kt) ]
its 7 because 7*7=49 and 49*7=343
so the cube root of 343 would be 7
