Answer:
n ≥ 6.24/x
Step-by-step explanation:
Given that :
Amount spent is atleast $6.24
Let price spent = p
p ≥ $6.24
If cost of granola bar = x
The number of granola bars, n purchased will be :
n ≥ 6.24/x
Since cost of granola bar isn't given, we represent it as x.
Answer:
Step-by-step explanation:
The volume of this cylindrical vase is V = πr²h. Substituting 3 in for r and 8 in for h, we get V = π(3 in)²(8 in), or 72π in³.
We'll need to pour 72π in³ of water into the vase.
<span>Assuming the reaction is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,

Answer:
5 pounds / Make sure to read the explanation so you know how to solve it
Step-by-step explanation:
First thing to do is:
Subtract 90 by 47.10 to find the amount of money she spent
She spent $42.90 on coffee and we know that it costs $8.58 per pound so that means that we should divide 42.90 by the cost per pound:
She bought 5 pounds of coffee
Hope I helped :]
Answer:
H is 16.8
Step-by-step explanation:
If you multiply 5.6 times 3 you get 16.8 and then you add 5.6 because 0.56 times 10 equals 5.6
