That number times .22 cause you move that sign over twice [I think]
Your equation is: 5h + 4 = 10h + 8
First subtract 5h from both sides:(So that variable terms stays in one side only)
=> 5h + 4 -5h = 10h + 8 -5h
=> 4 = 5h + 8
Now subtract 8 from both sides:(So constant term stays in the opposite side of variable terms)
=> 4 - 8 = 5h + 8 - 8
=> -4 = 5h
Now divide both sides by 5:(division by coefficient of variable)
=> -4/5 = 5h/5
=> -4/5 = h
=> h = -4/5 = -0.8
Girl age is 11 years old
Fathers age is 39 years old
How to solve it:
Let the girls age be x years
Let the fathers age be (x+28) years
X+X+28=50
2x=50-28
2x=22
X=11
(11+28)= 39
Answer:
575.8 cubic cm
Step-by-step explanation:
V(cone) = 1/3· π · r² · h
V = 1/3 · π · 25 · 12
V = 4(25)π or 100π = 314
V(half-sphere) = (4/3 · π r³)/2
V = (4/3π · 125) = 261.8
First go from bottom to top. then you must calculate how much is it to 70 to Point A which is 32 then u have to do the bottom part 45000 to 20 . which is 28 know 28 + 32 = 60. Hope this helps
