Answer:
96.46
Step-by-step explanation:
Volume of the Gallon =140 gallons
At time t=0, V(0)=40 gallons
V(t)=2t+k, Where K is a constant.
Since V(0)=40
V(0)=2(0)+k=40
k=40
V(t)=40+2t
The Change in Salt Concentration
Rearranging
Using Integrating Factor:
At t=0, C(0)=0.125, k_0=5
At V(t)=140
V(t)=40+2t=140
t=50
Just the tank overflows, C(t)=96.46
11x + 12(11x + 1) = 12
11x + 132x + 12 = 12
143x = 0
x = 0
y = 11x + 1
y = 11(0) + 1
y = 1 <==

About 492 pounds of milk and egg were consumed each year
<h3>Pie charts and percentages</h3>
Given the following parameters from the chart
Total consumption = 1640 pounds per person
The percentage of milk and egg = 100 -(38 + 10 + 10 +8 + 4)
The percentage of milk and egg = 30%
Determine the amount consumed each year
Amount of milk and egg consumed = 30% of 1640
Amount of milk and egg consumed = 492 pounds
Hence about 492 pounds of milk and egg were consumed each year
