We want the seconds to be converted in hours to work out the speed, so:
7200Seconds /60 / 60 =2 Hours
150 / 2 = 75
Therefore the car travels at 75kmh.
27305×10=
273050
that's what you meant right?
Answer:
19/35
Step-by-step explanation:
6/7 - 11/35
19/35
F(h(x)) means wherever you see x in the f(x) function you're gonna plug in the h(x) function:
f(h(x)) = (2x + 3) - 7
= 2x + 3 - 7
= 2x - 4
We know that V= 4/3 pi r^3
So r^3= 140/ ((4/3) pi)= 33.422538
Hence r= 3.221166
SA = 4 pi r^2
= 4 pi 3.221166^2
= 130.39 cm^2
= 130 cm^2
