Answer:
63 weeks
Step-by-step explanation:
252 - 3x = 378 - 5x
+ 5x +5x
Add 5x to both sides
252 + 2x = 378
-252 - 252
Subtract 252 from both sides
2x = 126
Divide 2 from both sides
x = 63
Check you work by plugging 63 where the x is
252 - 3(63)
252 - 189 = 63
378 - 5(63)
378- 315 = 63
You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.
Answer:
605 rupees
Step-by-step explanation:
add the parts of the ratio 3 + 4 = 7
divide the number of notes by 7 to find one part of the ratio
= 11 ← 1 part of the ratio
3 parts = 3 × 11 = 33 ← number of 5 rupee notes
4 parts = 4 × 11 = 44 ← number of 10 rupee notes
Amount of money = (33 × 5 ) + (44 × 10) = 165 + 440 = 605 rupees
