2 burgers and a soda the soda cost 2 dollars since sale tax was added to his meal at the rate of 10% so 20 cents added 19.80 minus 2.20 (I cant think cause im being rushed lol) which equals 17.60 divided by 2 8.80 dollars each
Answer:
The rate at which the radius is decreasing when the radius is 6 cm is approximately 3.316 × 10⁻³ cm/s
Step-by-step explanation:
The rate at which air is being lost from the balloon = 3/2 cm³/s
The rate at which the radius is decreasing when the radius is 6 cm long is given as follows;
The rate at which air is being lost from the balloon = dV/dt = 3/2 cm³/s
dV/dt = dV/dr × dr/dt
Where;
dr/dt = The rate at which the radius is decreasing
dV/dr = d(4/3×π×r³)/dr = 4·π·r²
Therefore, we have;
dr/dt = (dV//dt)/(dV/dr) = (3/2 cm³/s)/(4·π·r²)
dr/dt = (3/2 cm³/s)/(4·π·r²)
When r = 6 cm, we have;
dr/dt = (3/2 cm³/s)/(4 × π × (6 cm)²) ≈ 3.316 × 10⁻³ cm/s
Therefore, the rate at which the radius is decreasing, dr/dt, when the radius is 6 cm long ≈ 3.316 × 10⁻³ cm/s.

Let n represent the numerator of the original fraction, which is n/(n+4). After adding 1/2, the value is (2(n+4)+1)/(2(n+4)), so we have ...
n/(n+4) + 1/2 = (2(n+4)+1)/(2(n+4))
Simplifying gives ...
... (2n +(n+4))/(2(n+4)) = (2n +9)/(2(n+4))
Since the denominators are the same, we can work only with the numerators.
3n +4 = 2n +9
n = 5 . . . . . . . . . . . subtract 2n+4

The original fraction is 5/(5+4) = 5/9. Adding 1/2 gives ...
5/9 + 1/2 = 10/18 + 9/18 = 19/18
Note the numerator of this last fraction is 1 more than the denominator, which is twice the original denominator.
