Answer:
Step-by-step explanation:
Rate of leakage, R(t) = 1400 e^0.06t gallons/h
fraction remains , S(t) = e^(-0.32t)
initial contaminant = 1000 gallon
gallons contaminant present after t hour is S(t) R(t)
G(t) = S(t) R(t)


Put t = 18 hours

Taking log on both the sides
ln G = ln 1400 - 0.26 x 18
ln G = 7.244 - 4.68
ln G = 2.564
G = 13 gallons
The correct statement is:
A gallon of Moo Milk costs $5.12 What is the price, in dollars, of an 8 ounce glass of Moo Milk? There are 128 ounces in 1 gallon.
Solution:
Cost of 1 gallon of Moo Milk = $ 5.12
1 gallon = 128 ounces, so we can write:
Cost of 128 ounces of Moo Milk = $ 5.12
Cost of 1 ounce of Moo Milk = $ 5.12/128 = $ 0.04
Cost of 8 ounces of Moo Milk = $ 0.04 x 8 = $ 0.32
Thus, 8 ounces of Moo Milk will cost $ 0.32

Given that,
A boat tour guide expects his tour to travel at a rate of x mph on the first leg of the trip
On the return route, the boat travels against the current, decreasing the boat's rate by 10 mph
The group needs to travel an average of at least 24 mph
<em><u>Given inequality is:</u></em>

<em><u>We have to solve the inequality</u></em>




When we multiply or divide both sides by negative number, then we must flip the inequality sign


This is attached as figure below

Answer:x=4
Step-by-step explanation:
This triangle is an equilateral triangle with all angles equal.
Sum of angles in a triangle=180
17x-8+17x-8+17x-8=180
Collect like terms
17x+17x+17x-8-8-8=180
51x-24=180
51x=180+24
51x=204
Divide both sides by 51
51x/51=204/51
x=4
