on a map, 3/4 inch corresponds to an actual distance of 4 miles. how many square miles of actual area does a 3.5-inches-by-10-inches region of the map represent?
The actual area represented by 3.5-inches-by-10-inches on map is 995.5 miles.
As the measure of 3/4 inch is provided, working out the calculation for 1 inch.
3/4 inch = 4 miles
1 inch = (4×4)/3
1 inch = 16/3
1 inch = 5.33 miles
Now, the actual area of the region = 3.5 × 10
The actual area of the region = 35 inches²
Converting the area in square miles
The actual area of the region = 35 × (5.33)²
Taking square on Right Hand Side of the equation
The actual area of the region = 35 × 28.4
Performing multiplication on Right Hand Side of the equation
The actual area of the region = 995.5 square miles
Thus, the actual area of the region is 995.5 square miles.

a tank contains 1360l of pure water. a solution that contains 0.02kg of sugar per liter enters a tank at the rate 2 l/min. the solution is mixed and drains from the tank at the same rate. how much sugar is in the tank initially? find the amount of sugar in the tank after t minutes. find the concentration of sugar in the solution in the tank after 60 minutes
a) Amount of sugar in the tank initially is 0.
b) The amount of sugar in the tank after t minutes is 13.6(1 - [tex]e^{\frac{4t}{1360} }[/tex]).
c) The concentration of sugar in the solution in the tank after 60 minutes is 3.672.
a) Assign the sugar content of the tank for time t to the symbol A(t). Starting with only clean water, the tank
A(0) = 0
b) Sugar flows in at a rate of
(0.02 kg/L) × (2 L/min) = 0.04 kg/min
and flows out at a rate of
(A(t) ÷ 1360 kg/L) × (2 L/min) = (2A(t) ÷ 1360) kg/min
so that the net rate of change of A(t) is governed by the ODE,
dA(t) ÷ dt = (4 ÷ 100) - (2A(t) ÷ 1360)
A'(t) + (2A(t) ÷ 1360) = 2 ÷ 100
Multiply both sides by the integrating factor [tex]e^{\frac{4t}{1360} }[/tex] to condense the left side into the derivative of a product:
[tex]e^{\frac{4t}{1360} }[/tex] A'(t) + (2 [tex]e^{\frac{4t}{1360} }[/tex] A(t) ÷ 1360) = 4 [tex]e^{\frac{4t}{1360} }[/tex] ÷ 100
( [tex]e^{\frac{4t}{1360} }[/tex] A(t))' = 4 [tex]e^{\frac{4t}{1360} }[/tex] ÷ 100
Integrate both sides:
[tex]e^{\frac{4t}{1360} }[/tex] A(t) = ∫ 4 [tex]e^{\frac{4t}{1360} }[/tex] ÷ 100
[tex]e^{\frac{4t}{1360} }[/tex] A(t) = 13.6 [tex]e^{\frac{4t}{1360} }[/tex] + C
Solve A(t);
A(t) = 13.6 + C [tex]e^{\frac{4t}{1360} }[/tex]
A(0) = 0, substitute the value
0 = 13.6 + C [tex]e^{\frac{4t}{1360} }[/tex]
C = -13.6
so that the amount of sugar at any time t is,
A(t) = 13.6 - 13.6[tex]e^{\frac{4t}{1360} }[/tex]
A(t) = 13.6(1 - [tex]e^{\frac{4t}{1360} }[/tex])
c) As t → 60, the exponential term converges to 0 and is left with
[tex]\lim_{t \to \(60}[/tex] A(t) = 13.6 × (1 - 0.73)

The Cozo family has 5 children. While on vacation, they went to a play. They bought 5 tickets at the child’s price of $10.25 and 2 tickets at the adult’s price. If they spent a total of $89.15, how much was the price of each adult ticket?
Answer:
$18.95
Step-by-step explanation:
5(10.25) + 2x = 89.15
51.25 + 2x = 89.15 Subtract 51.25 from both sides
2x = 37.90 Divide both sides by 2
x = 18.95
Check:
5(10.25) + 2( 18.95) = 89.15
51.25 + 37.90 = 89.15
89.15 = 89.15
89.15 - 5(10.25)

quickly please!
The answer average speed is120KM/h
What is speed?
The speed of an object, also known as v in common parlance and kinematics, is the size of the change in position per unit of time or the size of the change in position over time; as such, it is a scalar quantity.The average speed of an object in a given period of time is equal to the distance travelled by the object divided by the length of the intervalthe instantaneous speed is the upper limit of the average speed as the length of Velocity and speed are different concepts.
Given in the question a car travels in 40Km/h
Total distance will be 's' = speed * time.
The total round trip avg speed is 60km/h
So time is taken to reach = s/40 hr
And time is taken to return back = s/x hr
The total time is given = 2s/60
We can write 2s/60 = s/40+s/x
⇒ 1/x = 1/30-1/40
⇒1/x = 1/120
⇒x = 120 KM/hour
Hence the, the average speed in the return journey is 120KM/hour.

White and solve a system of inequalities to model the following situation:
A retail store manager makes comty cloth facemasks for his employees during covid.
He has enough money to buy $100 worth of fabric.
Fabric costs $4 for a single layer mask and $6 for a mask with 2 layers of fabric.
It takes him 30 minutes to make a single layer mask and 1 hour to make double layer mask.
He only has 15 hours available to work on masks.
He wants to maximise his time and resources.
How many of each type of mask should he make
The system of inequalities for this situation are
Cost inequality = $4x + $6y ≤ $100
Time inequality = 30x + 60 ≤ 900
And the retailer should make 10 single layer and 10 2-layer mask by using the available time and cost.
System of inequalities
When two or more algebraic expressions are compared using the mathematical symbols like <, > ≤, or ≥, then they form an inequality. They are the mathematical expressions in which both sides are not equal.
Given,
A retail store manager makes cotton cloth facemasks for his employees during Covid. He has enough money to buy $100 worth of fabric. Fabric costs $4 for a single layer mask and $6 for a mask with 2 layers of fabric. It takes him 30 minutes to make a single layer mask and 1 hour to make double layer mask. He only has 15 hours available to work on masks. He wants to maximize his time and resources.
Here we need to find the system of inequalities and we also need to find each type of mask should he make.
Let us consider x be the number of single layer mask and y be the number of 2 layer mask.
Then based on the given cost, the cost inequality is written as,
$4x + $6y ≤ $100.
Here we know the time taken for each mask making, so, in the inequality form, it can be written as,
We know that,
1 hour = 60 minutes
So, 15 hours = 900
Therefore, the inequality of time is written as,
30x + 60 ≤ 900
While we plot these values on the graph then we get the graph like the following,
Here the blue line represent the time inequality and the red line represents the cost inequality.
Through the given graph, we have identified that the retailer should make 10 single layer and 10 2 layer mask by using the available time and cost.
