Answer:
Step-by-step explanation:
6f - 1 + 7f - 8 = 6f + 7f - 1 - 8
= 13f - 9
Combine like terms. Like terms have same variable with same power.
6(1/2w-3/4)
distribute
6*1/2 w - 6 * 3/4
3 w -18/4
divide top and bottom by 2
3w -9/2
change to a mixed number (9/2 = 2 with 1 left over)
3w -4 1/2
Answer:
Volume of cone = 130 cm³
Step-by-step explanation:
Given:
Volume of cylinder = 390 cm³
dimensions of cylinder = dimensions of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h
390 = πr²h
124.090909 = r²h
So,
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(22/7)r²h...........[124.090909 = r²h]
Volume of cone = (1/3)(22/7)(124.090909)
Volume of cone = 130 cm³
Work = Force * distance (along the line of force)
= 20N*10m
=200 N-m
=200 joules
38 is the answer. 25 cents + 10 cents + 3 cents
