I am not sure about number 2.
Subtract the distance of the Earth from the sun from the distance of Saturn from the sun to find the distance from Earth to Saturn:
1,424,000,000 - 149,600,000 = 1,274,400,000 km ( Saturn from Earth)
Divide the distance by the speed to find the time:
1,274,400,000 km / 28,000 km per hour = 45,514.2857 hours.
Round to 45,514 hours.
Answer:
153.36g
Step-by-step explanation:
Density is defined as the ratio of mass per unit volume of a material.
Density = Mass/Volume
Given the edge of a cube which is equivalent to its length L to be 6cm.
Density of the cube = 0.71g/cm³
Volume of the cube = L³
Volume = 6³
Volume of the cube = 216cm³
Mass = Density × Volume
Mass of the cube = 0.71×216
Mass of the cube = 153.36grams
28. it is not a right angle triangle because non of the angles is 90 degree
Answer:
4. Circumference = diameter × π
8× 3. 14= 25. 12 ~25. 1
5. 13×3. 14= 40. 82 ~40. 8
6. Diameter= radius ×2
3. 5×2=7
Diameter = 7
7× 3. 14= 21. 98 ~22
