125 workers can produce approximately 102.94 cars in 7 hours.Additionally, this assumes that the constant of Proportionality remains the same for different numbers of workers and hours worked.

We are given that the number of cars manufactured at an automobile plant varies jointly as the number of workers and the time they work. This can be expressed as:

C = kWT

where C is the number of cars produced, W is the number of workers, T is the time they work, and k is a constant of proportionality

We can use this formula to solve the problem. We are given that 85 workers can produce 136 cars in 8 hours, so we can set up an equation using this information:

136 = k(85)(8)

Solving for k, we get:

k = 2/17

Now we can use the formula to find the number of cars that 125 workers can produce in 7 hours:

C = (2/17)(125)(7)

C = 102.94

Therefore, 125 workers can produce approximately 102.94 cars in 7 hours.

It's important to note that this is an approximation since we have rounded the answer to two decimal places. Additionally, this assumes that the constant of proportionality remains the same for different numbers of workers and hours worked.

The correct statements that apply to the given limits are:

Option A: Multiply by (√(x + 2) + 3)/(√(x + 2) + 3)

Option D: "Divide out a common factor of x - 7."

Option E: The limit of the given expression is 1/6.

Option: We generally multiply by the conjugate of the expression to eliminate square roots in simplification. Thus, option A applies.

Option B: Get x - 1 in the numerator:

This statement is not correct. The expression does not involve x - 1 in the numerator.

Option C: Get (x - 7)(√(x + 2) - 3) in the denominator:

This statement is not correct due to the fact that we want to simplify the expression, and not introduce a more complex denominator.

Option D: Divide out a common factor of x - 7:

This statement is correct because by factoring out (x - 7) from both the numerator and denominator, we can cancel out the common factor.

Option E: Calculate the limit as 1/6:

After canceling out the common factor of x - 7, the simplified expression becomes:

lim x -> 7 (√(x + 2) - 3)/(x - 7)

= lim x -> 7 1/(√(x + 2) + 3)

To find the limit, we substitute the value x = 7 into the simplified expression:

lim x -> 7 1/(√(7 + 2) + 3) = 1/(√(9) + 3) = 1/(3 + 3) = 1/6

Bill's share = $56 Therefore, Bill received $56.

Let's start by setting up some equations based on the given information:

David's share = 1/7 * (Alex's share + Bill's share + Carl's share)

Alex's share = 3/4 * (Bill's share + Carl's share)

Bill's share = 2/5 * Carl's share

The sum of all four shares is $168.

We can use the fourth equation to solve for one of the shares in terms of the others:

Alex's share + Bill's share + Carl's share + David's share = $168

Alex's share + Bill's share + Carl's share = $168 - David's share

Substituting the other equations into this expression, we get:

Alex's share + (2/5 * Carl's share) + Carl's share + (1/7 * (Alex's share + (2/5 * Carl's share) + Carl's share)) = $168

Simplifying this equation, we get:

(8/7) * Alex's share + (22/35) * Carl's share = $168

Now we can use the other equations to solve for Carl's share, and then for Bill's share:

From Bill's share = 2/5 * Carl's share, we get Carl's share = (5/2) * Bill's share

From Alex's share = 3/4 * (Bill's share + Carl's share), we get Alex's share = (3/4) * ((7/2) * Bill's share) = (21/8) * Bill's share

Substituting these expressions into the equation we derived earlier, we get:

(8/7) * (21/8) * Bill's share + (22/35) * (5/2) * Bill's share = $168

3 * Bill's share = $168

To calculate the density of Saturn, we can use the following formula:

Density = Mass / Volume

We know the mass of Saturn is 5.68 x 1026 kg, and we can calculate the volume of Saturn using the following formula:

Volume = (4/3)πr³

where π is approximately equal to 3.14159 and r is the radius of Saturn, which is 5.6 x 107 m.

Plugging in these values, we get the following:

Density = 5.68 x 1026 kg / (4/3)π(5.6 x 107 m)³

Density = 0.687 kg/m³

Therefore, the density of Saturn is 0.687 kg/m³, which is less than the density of water (997 kg/m³). This means that Saturn would float on water.

The lease payment's present value is $258,743.55.

The journal entry for the lease on September 1, 2022, are:

- Lease equipment $258,743.55

- Lease liability $258,743.55

We have,

A.

To calculate the present value of the lease payments, we can use the present value formula:

PV = PMT x [ (1 - (1 + r)^{-n} / r]

where PV is the present value, PMT is the monthly lease payment, r is the monthly interest rate

(which is 8 % / 12 = 0.67%), and n is the number of lease payments

(which is 36 since it's a 3-year lease with monthly payments).

Plugging in the values.

PV = $8,000 x [(1 - (1 + 0.0067)^{-36} / 0.0067]

= $258,743.55

B.

The journal entry for the lease is on September 1, 2022.

i.e

Lease equipment $258,743.55

Lease liability $258,743.55

This records the initial recognition of the lease liability and the right-of-use asset at the present value of the lease payments.

The distance of bird away from the tower is  4.04 miles.

Given that,

Distance between A and B = 10 miles

To solve this problem,

Use the law of tangents and basic trigonometry.

Let  the distance from tower A to the bird = x

Then,

tan(180° - 64°) = x / (10 - d)

(where d is the distance from tower B to the bird)

tan(42°) = x / d

We can rearrange the first equation to get,

10 - d = x / tan(116°)

Substituting this into the second equation, we get:

⇒ tan(42°) = x / (x / tan(116°))

⇒ tan(42°) = tan(116°) x / x

⇒  x = 10 tan(42°) / (tan(116°) - tan(42°))

Plugging this into a calculator, we get:

x ≈ 4.04 miles

Therefore,

The exotic bird is approximately 4.04 miles away from tower A.

To calculate how long it would take to pay off a $1000 balance with an interest rate of 14% APR when making minimum payments of $20 each month, we need to consider the monthly interest and the decreasing balance.

First, let's calculate the monthly interest. The annual interest rate is 14%, so the monthly interest rate would be 14% divided by 12 months, which is approximately 1.167%.

Now, let's determine how much of the minimum payment goes towards interest each month. The remaining amount after deducting the interest is used to decrease the balance.

In the first month, the interest on the $1000 balance would be 1.167% of $1000, which is approximately $11.67. So, after making a $20 minimum payment, $11.67 is subtracted from the balance, resulting in a new balance of $988.33.

In the subsequent months, the same process is repeated. The interest is calculated based on the new balance, and the minimum payment is made. This continues until the balance reaches zero.

Given the small minimum payment of $20 and the interest accumulating on the balance, it would take significantly longer than 3 months, 1 year, or 3 years to pay off the $1000 balance. Therefore, the correct option is 6 years.

The slope-intercept form is expressed as;

y = mx + b

Where m is slope and b is the y-intercept.

Given the equation of the original line:
y = (7/5)x + 6

Using the slope intercept, slope m is 5/2

Slope m = 7/5

Note: the equation of a perpendicular line to y = (7/5)x + 6 must have a slope that is the negative reciprocal of the original slope.

Slope of perpendicular line = -1 / ( 7/5 )

Slope of perpendicular line = -5/7

Plug the slope m = -5/7 and point (2,-6) into point-slope formula and simplify.

The measure of the arc angles which subtends angles at the center are: MN = 72°, NQR = 180°, NQ = 108°, MRP = 193°, QR = 72, MR = 108, QMR = 288°, PQ = 13°, PRN = 265°, and MQN = 288°.

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

So;

arc angle MN = 72° {vertical angles}

arc angle NQR = 95 + 13 + 72 = 180°

arc angle NQ = 95 + 13 = 108°

arc angle MRP = 108 + 72 + 13 = 193°

arc angle QR = 72

arc angle MR = 95 + 13 = 108 {vertical angles}

arc angle QMR = 180 + 108 = 288°

arc angle PQ = 13° {sum of angles on a straight line}

arc angle PRN = 85 + 108 + 72 = 265°

arc angle MQN = 180 + 12 + 95 = 288°.

Therefore, the following are measures of the arc angles which subtends angles at the center: MN = 72°, NQR = 180°, NQ = 108°, MRP = 193°, QR = 72, MR = 108, QMR = 288°, PQ = 13°, PRN = 265°, and MQN = 288°.
