To maximize profit, the factory should manufacture 8 bicycles and 12 motorcycles.

Let us assume the number of bicycles as 'x'

Let us assume the number of motorcycles as 'y'.

The time constraint on machine A can be expressed as: 5x + 4y ≤ 120

The time constraint on machine B can be expressed as: 4x + 8y ≤ 144

To maximize profit, we need to maximize the objective function:

P = 40x + 50y

By graphing the constraints and finding the feasible region, we can determine the optimal solution.

Graphing the constraints:

For 5x + 4y ≤ 120:

Let's solve for y in terms of x: y ≤ (120 - 5x) / 4

For 4x + 8y ≤ 144:

Let's solve for y in terms of x: y ≤ (144 - 4x) / 8

The feasible region will be the intersection of the shaded regions:

y ≤ (120 - 5x) / 4

y ≤ (144 - 4x) / 8

Now, we will find the corner points of the feasible region:

When x = 0, y = 0

When x = 24, y = 0

When x = 8, y = 12

Substituting values into objective function P = 40x + 50y:

When x = 0, y = 0:

P = 40(0) + 50(0)

P = 0

When x = 24, y = 0:

P = 40(24) + 50(0)

P= 960

When x = 8, y = 12:

P = 40(8) + 50(12)

P = 1360.

Answer:

Amanda has 8 cousins

Step-by-step explanation:

Let C be the number of cousins Caleb has, A be the number of cousins Amanda has, and R be the number of cousins Ruby has:

[tex]C=2A\\R=5\\R=C-11\\\\R=C-11\\5=C-11\\16=C\\\\C=2A\\16=2A\\8=A[/tex]

Therefore, Amanda has 8 cousins.

Answer:

Amanda has 8 cousins.

Step-by-step explanation:

Let's use algebraic variables to solve the problem.

Let's assume the number of cousins Amanda has is represented by 'A'.

Since Caleb has twice as many cousins as Amanda, the number of cousins Caleb has is '2A'.

And Ruby has 5 cousins, which is 11 less than what Caleb has, so the number of cousins Caleb has is '5 + 11 = 16'.

Equating the two expressions for the number of cousins Caleb has:

2A = 16

Now we can solve for 'A', the number of cousins Amanda has:

Divide both sides of the equation by 2:

A = 16 / 2

A = 8

Therefore, Amanda has 8 cousins.

option C:

x² + y² = 16

Step-by-step explanation:

general equation of a circle is,

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the center of the circle

           r is the radius of the circle

according to the question the circle is centered at the origin so h and k will be 0

and r = 4

by substituting the values in the equation,

(x - 0)² + (y - 0)² = 4²

x² + y² = 16

First change them from mixed fractions to normal fractions.

= 5/4 + ( 11/3 + 23/4)

Then Find the LCM(lowest common factor) of 4 and 3 which is 12 so we'll multiply both 4 and 3 to the number so the answer would be 12. and also if we multiply the denominator we do the same to the numerator.

The length of the curve described by the function x = (y - 5)² where 0 ≤ y ≤ 1, is approximately A. 7.982.

Substituting the values back into the arc length formula, we have:

L = ∫√(dx/dt)² + (dy/dt)² dt

L = ∫√(2(t - 5))² + 1² dt

L = ∫√(4(t - 5)² + 1) dt

Now, let's integrate this expression over the given range 0 ≤ y ≤ 1:

L = ∫[0,1]√(4(t - 5)² + 1) dt

Approximating the integral with the midpoint rule:

L ≈ ∑[i=0 to n-1] √(4(t_i+1 - 5)² + 1) Δt

Let's choose n = 1000 for a reasonably accurate result. Thus, Δt = (1 - 0) / 1000 = 0.001.

Calculating the sum:

L ≈ ∑[i=0 to 999] √(4(t_i+1 - 5)² + 1) * 0.001

The probability that exactly seven claims will be filed during the next week is approximately 0.1038 or 10.38%.

To determine the probability of exactly seven claims being filed during the next week, we need to use the Poisson distribution. The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space when the events occur with a known average rate and independently of the time since the last event.

In this case, we are given that the average number of claims filed per week is seven. This average rate is also the parameter λ (lambda) of the Poisson distribution.

The probability mass function (PMF) of the Poisson distribution is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

Where X is the random variable representing the number of claims filed, k is the specific number of claims we are interested in (in this case, k = 7), e is the base of the natural logarithm (approximately 2.71828), and k! represents the factorial of k.

Substituting the given average rate of seven claims per week into the equation, we have:

P(X = 7) = (e^(-7) * 7^7) / 7!

Calculating this expression will give us the probability of exactly seven claims being filed during the next week.

P(X = 7) ≈ 0.1038

Therefore, the probability that exactly seven claims will be filed during the next week is approximately 0.1038 or 10.38%.

This means that, on average, we can expect approximately 10.38% of weeks to have exactly seven claims filed based on the given average rate of seven claims per week.

Answer:

To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:

8x = x + 9

Solving for x, we get:

x = 1.5

Therefore, AB = 8x = 8(1.5) = 12.

To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:

AB^2 + BD^2 = AD^2

Substituting the values, we get:

12^2 + BD^2 = (1.5 + 9)^2

Simplifying, we get:

BD^2 = 56.25

Taking the square root of both sides, we get:

BD = 7.5

Hence, the length of AB is 12 and the length of BD is 7.5.

To find the value of the expression sin(45°) + cos(67°) - 4554 + 97 + 64555 + 755577652 - 6622, we can start by evaluating the trigonometric functions and then simplifying the arithmetic operations.

First, let's find the values of sin(45°) and cos(67°).

sin(45°) is equal to √2/2, approximately 0.7071, and cos(67°) is equal to 0.3919 (rounded to four decimal places).

Now, we can substitute these values into the expression:

0.7071 + 0.3919 - 4554 + 97 + 64555 + 755577652 - 6622

Next, let's perform the arithmetic operations:

0.7071 + 0.3919 = 1.099 (rounded to three decimal places)

1.099 - 4554 + 97 + 64555 + 755577652 - 6622

Simplifying further:

-4554 + 97 + 64555 = 60098

60098 + 755577652 - 6622 = 755642128

The producer surplus is approximately $663.772.

To find the producer surplus, we need to calculate the area between the supply curve and the selling price line.

The supply curve is given by the equation:

[tex]s(x) = 180 + 0.3x^{(3/2)[/tex]

where x is the product quantity.

Let's set the selling price to $250.

We want to find the quantity (x) at which the selling price intersects the supply curve. So, we can set:

[tex]250 = 180 + 0.3x^{(3/2)[/tex]

Now, let's solve this equation to find the value of x:

[tex]250 - 180 = 0.3x^{(3/2)[/tex]

[tex]70 = 0.3x^{(3/2)[/tex]

Divide both sides by 0.3:

[tex]x^{(3/2)} = 70 / 0.3[/tex]

[tex]x^{(3/2)} = 233.33[/tex]

Now, we can solve for x by raising both sides to the power of 2/3:

[tex]x = (233.33)^{(2/3)[/tex]

x ≈ 24.88

So, the quantity (x) at which the selling price intersects the supply curve is approximately 24.88.

To calculate the producer surplus, we need to find the area between the supply curve and the selling price line from 0 to x.

The formula for the producer surplus is:

Producer Surplus = ∫[0 to x] (s(x) - Selling Price) dx

Using the given supply curve [tex]s(x) = 180 + 0.3x^{(3/2)[/tex] and the selling price of $250, we can evaluate the integral:

Producer Surplus = ∫[0 to 24.88] ([tex]180 + 0.3x^{(3/2)[/tex]) dx

When a house is sold for $73,400.00 with a commission rate of 5 1/2 %, the agent's earnings would be $2,220.35.

To calculate the agent's earnings, we need to determine the total commission earned from the sale of the house and then calculate 55% of that amount.

First, we need to calculate the total commission earned from the sale of the house. The commission rate is given as 5 1/2 %, which can be written as a decimal as 0.055.

The total commission can be found by multiplying the sale price of the house ($73,400.00) by the commission rate (0.055):

Total Commission = $73,400.00 * 0.055

= $4,037.00

Now, we need to determine the agent's earnings, which is 55% of the total commission. We can calculate this by multiplying the total commission by 55% or 0.55:

Agent's Earnings = $4,037.00 * 0.55

= $2,220.35

Therefore, when a house is sold for $73,400.00 with a commission rate of 5 1/2 %, the agent's earnings would be $2,220.35.

for the first one the sales on table is going downn while the days are increasing

for the second one the arrow going up signifies that the sales are going up according to days

Your lab regularly runs tests on mice, resulting in several bags of leftover mouse food sitting in your storage closet, the lab will need more food around day 116 of the year.

To determine if the lab's reserve of mouse meals will hold up for the entirety of subsequent year, we need to research the fee at which the food reserves are reducing.

Let's calculate the common day by day decrease in meals reserves:

Average daily decrease = (Initial food reserves - Final food reserves) / (Number of days)

Initial food reserves = 112.6 kg

Final food reserves = 109.1 kg

Number of days = 8 (from December 13 to December 21)

Average daily decrease = (112.6 kg - 109.1 kg) / 8 ≈ 0.4375 kg/day

Number of days until food reserves reach zero = Final food reserves / Average daily decrease

Number of days until food reserves reach zero = 109.1 kg / 0.4375 kg/day ≈ 249.14 days

Thus, the lab will need more food approximately 365 - 249.14 = 115.86 days into the year. Round it up to the nearest whole number, and the lab will need more food around day 116 of the year.
