The area of the circular pond's surface is approximately 39.8 m².
1. The area of a circular surface can be calculated using the formula: A = πr², where A represents the area and r represents the radius of the circle.
2. Given that the radius of the pond is 3.56 m, we can substitute this value into the formula.
3. Calculate the area by squaring the radius and multiplying it by π: A = π × (3.56 m)².
4. Simplify the expression by calculating the square of the radius: A = π × 12.6736 m².
5. Multiply the result by π, which is approximately 3.14159: A ≈ 3.14159 × 12.6736 m².
6. Perform the multiplication to find the final result: A ≈ 39.800233184 m².
7. Round the area to one decimal place: A ≈ 39.8 m².
Therefore, the area of the circular pond's surface is approximately 39.8 m².

Answer:
40y^5√6y (B)
Step-by-step explanation:
Let's multiply 2√25y^8 * 4√6y^3:
8√150y^11 (When you multiply exponents with the same base, you can just add the exponents and keep the same base:
Ex. 4^5 * 4^9 = 4^14)

Class A, B and C were given some chocolate bars to sell for their fundraising event. The average number of chocolate bars the 3 classes had at first was 225. After Class B sold twice as many chocolate bars as Class A and Class C sold 3/4 as many chocolate bars as Class B, the average number of chocolate bars the 3 classes had left was 45. How many chocolate bars did Class A and Class C sell altogether?
Class A and Class C sell 187.5 altogether
How many chocolate bars did Class A and Class C sell altogether?Represent the classes with their initials
So, we have
B = 2A
C = 3/4 * B = 3/4 * 2A
C = 3/2A
The total number of bars they had initially was
A + B + C = Total
A + 2A + 3/2A = Total
Total = 4.5A
The average number of bars the 3 classes had initially was 225,
So
4.5A = 225
A = 75
For Class A and Class C together, we have
Class A and C = A + 3/2A
Class A and C = 75 + 3/2 * 75
Class A and C = 187.5

In which:
\(\pi\) is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 95% confidence level, hence\(\alpha = 0.95\), z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.

A soil supplement that weighs 16 lb contains iron, potassium, and mulch. The supplement contains thirteen times as much mulch as iron and twice as much potassium as iron. Find the amount of mulch in the soil supplement. lb
Answer:
The answer is below
Step-by-step explanation:
Let x represent the amount of iron, y represent the amount of potassium and z represent the amount of mulch.
Since the supplement weighs 16 lb, hence:
x + y + z = 16 (1)
Also supplement contains thirteen times as much mulch as iron. Therefore:
x = 13z
x - 13z = 0 (2)
The supplement also has twice as much potassium as iron, hence:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2 and 3 simultaneously gives:
x = 10.1 lb, y = 5.1 lb, z = 0.8 lb
This means that the soil supplement contains 0.8 lb of mulch

Three machines A, B and C operate independently in a factory. Machine A is out of action for 10% of the time, while machine B is out of action for 5% of the time and machine C for 20% of the time. A rush order has to be commenced at midday tomorrow. What is the probability that at this time: g
The probability that all three machines (A, B, and C) are operational at midday tomorrow is 0.684, or 68.4% when expressed as a percentage.
To find the probability that all three machines are operational at midday tomorrow, we need to multiply the probabilities of each machine being in action.
The probability of machine A being in action is 1 - 0.10 = 0.90 (since it is out of action for 10% of the time).
The probability of machine B being in action is 1 - 0.05 = 0.95 (since it is out of action for 5% of the time).
The probability of machine C being in action is 1 - 0.20 = 0.80 (since it is out of action for 20% of the time).
Since the machines operate independently, we can multiply these probabilities together to get the probability that all three machines are operational:
Probability (All machines operational) = Probability (Machine A in action) * Probability (Machine B in action) * Probability (Machine C in action)
= 0.90 * 0.95 * 0.80
= 0.684
Therefore, the probability that all three machines (A, B, and C) are operational at midday tomorrow is 0.684, or 68.4% when expressed as a percentage.

Convert 315 degrees to radian
Answer:
\(\frac{7\pi }{4}\) radians
Step-by-step explanation:
to convert degrees to radians
radians = degrees × \(\frac{\pi }{180}\) , then
radian measure = 315° × \(\frac{\pi }{180}\) ( cancel 315 and 180 by 45 )
= 7 × \(\frac{\pi }{4}\)
= \(\frac{7\pi }{4}\)
315 degrees is equal to 5.49779 radians.
To convert degrees to radians, you need to multiply the degree measure by the conversion factor of π/180.
Let's convert 315 degrees to radians:
315 degrees × (π/180)
315×3.14 /180
= 5.49779 radians
Therefore, 315 degrees is equal to 5.49779 radians.

find three positive numbers whose sum is 220 and whose product is a maximum. (enter your answers as a comma-separated list.)
x = y = z = 73.33 are three positive numbers whose sum is 220 and whose product is a maximum.
Using Lagrange's multiplier
It is given that x+ y+ z =220
To maximize product
\(f(x,y,z)=x*y*z\)
And the constraint is
x +y +z=220
\(g(x,y,z)=x+y+z-220\)
And the gradients are:
\(\nabla{f}=(xy,yz,xz)\)
\(\nabla{g}=(1,1,1)\)
Their relation is:
\(f=\lambda\nabla{g}\)
\((xy,yz,zx)=\lambda(1,1,1)\)
we get,
\(xy=yz=zx=\lambda\)
Thus x=y=z
3x=220
x=220/3=73.33
Hence x = y = z = 73.33

A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?
Answer:
17 m² or 17 square meters
Step-by-step explanation:
A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?
Area of a trapezoid =1/2(b1 + b2)h
Where
b1 = First base length = 5m
b2 = Second base length = 3.5 m
Height = 4m
= 1/2(5m + 3.5m) × 4m
= 1/2(8.5m) × 4m
= 1/2 × 8.5m × 4m
= 17 m²
Therefore, the area of the trapezoid is 17 m² or 17 square meters
To solve the separable differential equation dy / dx = 8y, we must find two separate integrals (put the constant 8 in the y integral and use C for the constant of integration): dy = and dx = Solving for y we get that y = (you must use k as your constant) and find the particular solution satisfying the initial condition y(0) = -2. y(x) =
To solve the separable differential equation dy/dx = 8y, we must first separate the variables, resulting in two separate integrals. We will have dy/y = 8 dx. Now, we need to find the integrals:
1) Integral of dy/y:
∫(1/y) dy
2) Integral of 8 dx:
∫8 dx
Next, we solve the integrals:
1) ∫(1/y) dy = ln|y| + C₁
2) ∫8 dx = 8x + C₂
Now, we combine these results to find the general solution:
ln|y| = 8x + C, where C = C₂ - C₁.
To solve for y, we take the exponent of both sides:
y = e^(8x + C) = e^(8x)e^C. We can write e^C as a new constant k, so y = ke^(8x).
Now, we need to find the particular solution satisfying the initial condition y(0) = -2. To do this, plug in the values into the equation:
-2 = k * e^(8 * 0)
-2 = k * e^0
-2 = k * 1
k = -2
So the particular solution satisfying the initial condition is y(x) = -2e^(8x).

Suppose that a sales person observes that if an item is priced at $9 per item then 6 items are sold. If 4 items are sold for $11 per item then find a linear equation to model the number y of items sold for x dollars per item. Find the slope-intercept form of the equation of the line.
Answer:
y = -x + 15
Step-by-step explanation:
if an item is priced at $9 per item then 6 items are sold.
Thus, the input is 9 while the output is 6.
Thus, we can say; x, y = (9, 6)
4 items are sold for $11 per item. Thus, the coordinate is; (11, 4)
Now,slope is;
m = (y2 - y1)/(x2 - x1)
m = (4 - 6)/(11 - 9)
m = -2/2
m = -1
We know that slope intercept form is;
y = mx + c
Let's try the first point.
Thus;
6 = -1(9) + c
6 + 9 = c
c = 15
Thus, equation of line is;
y = -x + 15
