Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000
Explanation:
False unlike the outer core the inner core is made out of mostly solid because it contains iron
Answer:
75% = 
= 0.75
20% = 
= 0.20
0.8% = 
= 0.008
Explanation:
75% means "75 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 75% would become 0.75
20% means "20 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 20% would become 0.20
0.8% means "0.8 for every 100", but it's easier to understand if you write it as "8 for every 1000". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 0.8% would become 0.008
Hope this helps.
