Answer:
36,000 miles in one hour.
Explanation:
Because there are 60 seconds in a minute and 60 minutes in an hour so to find out how many seconds are in an hour you multipy 60x60 to get 3600. Then to find out how many miles in the 3600 seconds you multiply 10 x 3600 to get 36000.
Answer:
the answer is b, 0.89
Explanation:
A cube has a height of 8 cm and a mass of 457 g. What is its density?
a. 233,984 g/cm
b. 0.89g/cm3
c. 1.12 g/cm3
Density = mass/volume
the volume of the cube is 8X8X8=512cm3
the mass is 457 gm
the density is 457/512 = 0.889 gm/cm3
the answer is b, 0.89
