Answer:
The volume of the cubical tank is 42 cm x 42 cm x 42 cm = 84,764 cm^3
If the tank is filled up to the height of its edge, it means that the water filled up to the height of 42cm, and the volume of the water filled is 42cm x 42cm x 42cm = 84,764 cm^3
The volume of 1 jug = 1.3 litres = 1300 cm^3
The total volume of water spilled = 2.45 litres = 2450 cm^3
The total volume of water that can be filled into jugs = total volume of water in tank - volume spilled = 84764 - 2450 = 82314 cm^3
If we divide the total volume of water that can be filled into jugs by the volume of 1 jug, we get 82314/1300 = 63.6
The maximum number of jugs that were fully filled is 63, as the fraction of 0.6 jugs is not possible.
inspect a sketch of typical solution curves to determine the points for which the initial value problem has a unique solution.
We have to find solutions for the given differential equation when
y = 0, y = 1/(k-x) and y(a) = b using ordinary differential equations.
We have dy / dx = y^2
a. let's define the given y = 1/(k-x)
derive the above equation with respect to x :
dy / dx = y' = 1/(k-x)^2
So this is the general solution.
b) We would want a singular solution that is not included in the general form. Here we could use y = 0
dy / dx = 0 = 0^2
so,this is a trivial singular solution.
c) If we have y(a) = b,
then, y = 1(k-a) = b
To find the value of k we use the other condition: y'(^2) = 4 x y(2)
1/(k-a)^2 = 4 x 1/(k-a)
k - 2 = 1/4
therefore, k = 9/4
hence we got, y = 1/(9/4 - a) = b
So the points (a, b) are of the form: (a, 1/(9/4 - a))

Step-by-step explanation:
A diet is being prepared for WTAMU dorms. The varied diet is to be made of three foods: A, B and C. Food A costs $2.25 per pound and contains 500 calories. Food B costs $ 2 per pound and contains 700 calories. Food C costs $ 3 per pound and contains 600 calories No more than 0.75 pounds of food C can be used per resident. No less than 2 pounds of food B should be used per resident. The objective is to feed the students at the least cost, but the diet must have at least 1800 calories.
If we define the decision variables as A: pounds of food A, B: pounds of food B, and C pounds of food C, the object function is to minimize Blank 1. In addition to non-negative constraints, other constraints are Blank 2,Blank 3, and Blank 4.
(1. No need to use multiplication sign. For example, just write 10A not 10*A. For greater(less) than sign, just write it as >= (<=).
2. Also please leave no space in equation. For example, write A<=100, not A <= 100.
3. Please write decimal number for example as 0.32 not .32 when applicable. )
This problem is designed to minimize the cost of feeding students in the dorms while providing a minimum of 1800 calories. The objective function is to minimize the cost of the diet, which is calculated by multiplying the pounds of each food by its cost and adding them together. The constraints of the problem are that A must be greater than or equal to 0, B must be greater than or equal to 2, and C must be less than or equal to 0.75.
1. 2.25A + 2B + 3C
2. A >= 0
3. B >= 2
4. C <= 0.75
The objective of this problem is to minimize the cost of feeding students in the dorms, while the diet must contain a minimum of 1800 calories. To achieve this, three decision variables were defined: A, B, and C, which represent the pounds of food A, B, and C respectively. The objective function is to minimize the cost of the diet, which is calculated by multiplying the pounds of each food by its cost, and adding them together. There are three constraints in the problem: A must be greater than or equal to 0, B must be greater than or equal to 2, and C must be less than or equal to 0.75. These constraints ensure that the diet contains the desired amount of each food and that the total calories meet the minimum requirements.

there exists an intewger that is greater than 5 and whose square is smaller than 40, express as a mathematical quantifiers
there exists an integer that is greater than 5 and whose square is smaller than 40, express as a mathematical quantifiers ∃x∈ℤ: x > 5 ∧ x² < 40
1. Start by writing down the equation: x² < 40
2. Take the square root of both sides of the equation to isolate the variable x: √x² < √40
3. Simplify both sides of the equation: x < √40
4. Check that the result makes sense: x < 6.3
5. Take the integer part of the result: x < 6
6. Since the requirement is that x is greater than 5, the answer is x = 6.
We start by writing the equation x² < 40 and then take the square root of both sides to get x < √40. We check that the result is reasonable and then take the integer part of the result to get x < 6. Since the requirement is that x is greater than 5, the answer is x = 6. To confirm, we can calculate that x² = 36 which is smaller than 40, and indeed, 6 is greater than 5. Therefore, the integer that is greater than 5 and whose square is smaller than 40 is 6. This can be expressed mathematically as ∃x∈ℤ: x > 5 ∧ x² < 40 which translates to: There exists an integer x such that x is greater than 5 and the square of x is smaller than 40.

a bicycle has wheels 32 inches in diameter. a tachometer determines the weheels are rotating at 150 rpm(revolutions per minute). Find the speed the bicycle is traveling down the road.
The speed of the bicycle is 381 meters per minutes
we know that,
revolutions per minute = speed in meters per minute / circumference in meters.
Diameter = 32 inches
Circumference of the wheel = 2πr
r = Diameter/2 = 32/2 = 16
Circumference = 2 × π × 16
= 100.5714 inches
Approximately = 100 inches
we know that,
1 inch = 0.0254 meter
100 inches = x
x = 100 × 0.0254 meters
x = 2.54 meters
Hence:
Revolutions per minute = Speed in meters per minute / circumference in meters.
Speed = Revolutions per minute × circumference in meters.
Speed = 150 RPM × 2.54 meters
Speed = 381 meters per minutes

Several college students conduct a survey at their local community college. They find that 67% of the students live with their parents in the house they grew up in. Of the students who live with their parents 23% live within walking distance to campus. Of the students who do not live with their parents only
6% live within walking distance to campus. a) What is the probability of a student living within walking distance to campus? ( 1 point) b) What is the probability given a student lives within walking distance to campus they live with their parents? (1 point) c) Are living with parents and living within walking distance independent events? (2 points)
a) The probability of a student living within walking distance of campus is 0.1521.
To find the probability of a student living within walking distance of the campus, we can use the formula for conditional probability:
P(A and B) = P(A) * P(B|A).
For this situation, An is "living within walking distance to campus" and B is "living with parents."
Thus, P(A and B) = (0.23)(0.67) + (0.06)(0.33) = 0.1521.
Hence, the probability of a student living within walking distance of campus is 0.1521.
b) The probability given a student living within walking distance of campus they experience with their parents is 0.67.
To find the probability given a student day to day routines within walking distance to campus they experience with their parents, we can use the formula for conditional probability:
P(A|B) = P(A and B)/P(B).
In this situation, A is "living with parents" and B is "living within walking distance to campus."
Thus, P(A|B) = P(A and B)/P(B) = (0.23)(0.67)/0.1521 = 0.67.
Subsequently, the probability gave a student living within walking distance of campus experience with their parents is 0.67.
c) Living with parents and living within walking distance are independent events.
To decide whether living with parents and living within walking distance are independent events, we can analyze P(A|B) with P(A).
On the off chance that P(A|B) = P(A), the events are independent. For this situation, P(A|B) = 0.67 and P(A) = 0.67, so living with parents and living within walking distance are independent events.

The sample has 3.33% of defective bulbs so, B. The shipment will not be replaced.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, If a shipment has at least 5% defective light bulbs, it will be replaced.
Now, A sample of 60 light bulbs has 2 that are defective.
Therefore, The percentage of defective bulbs is,
= (2/60)×100%.
= (1/30)×100%.
= 3.33%, So, the shipment will not be replaced.
