You have a 45-gallon jug and a 124-gallon jug. neither of the jugs has any markings (although you do know their capacities). describe a way to measure exactly one gallon of water.
Answers
Amount of water = 124 x 4 = 496 gallons
Then use the 45-gallon jug to scoop out the water 11 times.
Amount of water scooped out = 11 x 45 = 455 gallons
Water remaining = 496 - 450 = 1 gallon.
11*45 = 495
Fill the 124-gallon jug 4 times, emptying it each time into the 45-gallon jug. After the 45-gallon jug has been filled 11 times, there will be 1 gallon remaining in the 124-gallon jug.
_____
Mathematically, this works fine. In practice, you're looking for a 1-gallon difference after handling 495 gallons of water. That's about 0.2% of the total amount of water transferred. Any error along the way will substantially affect the outcome.

This graph shows how much Marie earns babysitting compared with the number of hours she works select the correct statement about the graph
Answers
The graph reflects that she is getting paid 10 dollars an hour
If you plot the points, you will see she makes 5 dollars every half hour
Answer:
Option D is the answer.
Step-by-step explanation:
This graph represents a linear function representing earnings of Marie at y axis and hours of working at x axis. To get the change in Marie's earnings for every 5 hours we will find the slope of the given line.
Slope of the line will define the rate of change in earning of Marie with respect to the time.
End points of the line at time t = 0 and t = 5 hours are (0, 0) and (5, 50).
Therefore slope = [tex]\frac{y-y'}{x-x'}=\frac{50-0}{5-0}=\frac{50}{5}=10[/tex]
So for each hour she works her earnings go up by $10.
Option D is the correct option.
Find the area of the figure
Answers
The parallelogram, you can just do base * height. The base is 11 yards, and the height is 4 yards. 11 * 4 = 44 square yards.
Now for the trapezoid. If you split it up into a rectangle and a triangle, it becomes much more easier to solve. The rectangle and triangles can be made by splitting the figure down the center. This makes a rectangle with a length of 7 yards and a height of 8, and a triangle with a base of 7 yards and a height of 8 as well.
Solve for the area of both shapes.
The rectangle: Multiply length * height: 7 * 8 = 56 square yards
The triangle: Multiply base * height, and then divide by 2: 7 * 8 = 56
56 / 2 = 28 square yards
Now add the areas together.
28 + 56 + 44 = 128 square yards

600 π in3
Answers
pi*r²*h
pi*r²*h/2
r=10/2-----> r=5 in
h=12 in
=pi*5²*12/2----> 150*pi in³
so finally the correct answer would be the first option
150*pi in3
The required exact volume of the half cylinder is 150 π in³. Option A is correct.
To calculate the volume of a half cylinder, we need to find the volume of a full cylinder and then divide it by 2.
The formula for the volume of a cylinder is given by:
Volume = π * r² * h
where π is a constant approximately equal to 3.14159, r is the radius of the cylinder, and h is the height or length of the cylinder.
Given that the diameter of the cylinder is 10 inches, we can find the radius by dividing the diameter by 2:
Radius (r) = 10 in / 2 = 5 in
The height or length of the cylinder is given as 12 inches.
Now we can calculate the volume of the full cylinder:
Volume = π * (5 in)² * 12 in = 300 π in^3
Finally, to find the volume of the half cylinder, we divide the volume of the full cylinder by 2:
Volume of Half Cylinder = (300 π in³) / 2 = 150 π in³
Therefore, the exact volume of the half cylinder is 150 π in³.

A regular polygon with 32 sides has 16 lines of symmetry.
What is Polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
We need to find the number of lines of symmetry does a regular polygon with 32 sides have.
The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry
A regular polygon with 32 sides has 16 lines of symmetry.
This is because each side is equal in length and angles, creating a mirrored effect when each side is divided in half.

tan(19.9) = y/x
tan(21.8) = y/(x-50) ( x is 50 feet closer so subtract 50 from x)
find the tan of the angles:
tan19.9 = 0.362
tan21.8 = 0.400
replace those values in the equations:
0.362 = y /x
0.400 = y / (x-50)
rewrite to solve for height:
0.362x = y
0.400(x-50) = y distribute the 0.400 and rewrite as 0.400x-20 =y
now solve:
0.362x = 0.400x-20
add 20 to each side:
0.362x +20 = 0.400x
subtract 0.362x from each side:
20 = 0.038x
divide both sides by 0.038
x = 20 / 0.038 = 526.3 feet
now that x is known replace x in the original equation and solve for y:
tan19.9 = y /x
0.362 = y / 526.3
y = 0.362 x 526.3
y = 190.5
the height of the tower is 190.5 feet

Given that,
You have been averaging 55 sales per day. increase his or her sales per day by 10% in the next monthBased on the above information, the calculation is as follows:
[tex]= 55 \times 1.10 \times 30 days[/tex]
= 1,815
Learn more: https://brainly.com/question/25914450?referrer=searchResults
Final answer:
To meet the new policy of a 10% increase in sales, you would multiply your current average sales by the increase percentage and round up to the nearest whole number. Starting from 55 sales, a 10% increase results in an additional 5.5 sales, which when rounded up equals 6. Therefore, you need to achieve 61 sales per day.
Explanation:
If you have been averaging 55 sales per day and need to increase your sales by 10%, you will first need to calculate the increase. To calculate a 10% increase, you multiply your current average sales (55) by the percentage increase (10%), expressed as a decimal (0.10). The increase in sales can be found by the formula:
Increase = Current Sales × Percentage Increase
For your sales:
Increase = 55 × 0.10 = 5.5 sales
Since you need to round up, the increase will be 6 sales when considering whole units, as you cannot sell half a unit.
Therefore, the new target sales per day will be:
New Sales Target = Current Sales + Increase
New Sales Target = 55 + 6 = 61 sales
By next month, you will need to be up to 61 sales per day after rounding up.

[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]
Step-by-step explanation:
The product rule is:
[tex]f(x) = g(x)h(x)[/tex]
[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]
In this problem, we have that:
[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]
So
[tex]g(x) = 1 + 5x^{2}[/tex]
[tex]g^{\prime}(x) = 10x[/tex]
[tex]h(x) = x - x^{2}[/tex]
[tex]h^{\prime}(x) = 1 - 2x[/tex].
[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]
[tex]f^{\prime}(x) = (10x)*(x - x^{2}) + (1 + 5x^{2})(1-2x)[/tex]
[tex]f^{\prime}(x) = 10x^{2} - 10x^{3} + 1 - 2x + 5x^{2} - 10x^{3}[/tex]
[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]
Multiplication first:
[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]
[tex]f(x) = x - x^{2} + 5x^{3} - 5x^{4}[/tex]
[tex]f(x) = -5x^{4} + 5x^{3} - x^{2} + x[/tex]
[tex]f^{\prime}(x) = -20x^{3} + 15x^{2} - 2x + 1[/tex]
Comparing the results, we can see that the derivatives obtained using the two methods are indeed the same. The answer is yes.
What's the function about?The derivative of f(x) = (1 + 5x2)(x − x2) can be found using the product rule and by performing the multiplication first.
Using the product rule:
The product rule states that the derivative of f(x)g(x) is f′(x)g(x)+f(x)g′(x).
In this case, f(x) = 1 + 5x2 and g(x) = x − x2. So the derivative of f(x)g(x) is:
f′(x)g(x)+f(x)g′(x)
=(10x+10x3)(x−x2)+(1+5x2)(2x−2x3)
=10x2−10x3+10x3−10x4+2x−2x3+1+10x2−10x3
=−10x4+12x2+2x
Performing the multiplication first:
We can first multiply out the expression (1 + 5x2)(x − x2) to get:
x2−5x4+x3−5x3+x−x2
=−5x4+12x2+x
Then, we can take the derivative of this expression to get the same derivative as we found using the product rule:
f′(x)=−10x4+12x2+2x
Therefore, the derivative of f(x) = (1 + 5x2)(x − x2) is -10x4+12x2+2x, regardless of whether we use the product rule or perform the multiplication first.

A rectangular storage area is to be constructed along the side of a tall building. a security fence is required along the remaining 3 sides of the area. what is the maximum area that can be enclosed with 800 m of fencing? (a = lw)
Answers
A = lw = l(800 -l)/2
This is the equation of a downward-opening parabola with zeros at l=0 and l=800. The zeros are symmetrical about the axis of symmetry of the parabola, which axis goes through the vertex. That is, the vertex is located at
l = (0 +800)/2 = 400
The maximum aea that can be enclosed is 400 m long by 200 m wide, so is
(400 m)×(200 m) = 80,000 m²
To find the maximum area enclosed with 800 m of fencing, the dimensions of the rectangular storage area need to be determined. The perimeter equation is derived to eliminate a variable, allowing the area to be expressed in terms of the remaining variable. Using this approach, the dimensions that maximize the area can be found.
Explanation:To find the maximum area that can be enclosed with 800 m of fencing, we need to determine the dimensions that will result in the largest possible area. Let's assume the length of the rectangular storage area is L and the width is W.
Since there are 3 sides already covered by the security fence, the perimeter of the rectangular storage area will be: 2L + W = 800 m.
To find the maximum area, we need to eliminate one variable from the equation above. We can do this by expressing W in terms of L and substituting it back into the area formula A = LW.
By applying this approach, we can find the dimensions of the rectangular storage area that will enclose the maximum area with 800 m of fencing.
