To determine Km from a double-reciprocal plot, you would choose option (A) which is to multiply the reciprocal of the x-axis intercept by -1.

In the double-reciprocal plot equation, the x-axis intercept is -1/Km, and the y-axis intercept is 1/Vmax. Therefore, if you take the reciprocal of the x-axis intercept, you get -Km, and multiplying it by -1 gives you Km.

This method is preferred because it is more accurate than estimating Km based on the position of the curve on the plot or by taking the x-axis intercept where V0 = 1/2 Vmax, which can be influenced by experimental error.

Answer:The second one is better

Step-by-step explanation:

To determine the optimal order quantity for Rocky Mountain Tire Center, you must consider ordering costs, storage costs, and the purchase price of the tires. The order quantity should minimize the total cost including both ordering cost and storage cost.

The EOQ formula is given by: EOQ = √((2DS) / H)

Where: D = Annual demand (7,000 go-cart tires)

S = Ordering cost per order ($40) H = Holding cost - percentage of the purchase price (40% of the purchase price)

we need to determine the purchase price per tire based on the quantity ordered.

EOQ = √((2 * 7,000 * 40) / (0.4 * 15))

=118 tires

they should order approximately 118 tires.

Let's denote the time it takes for the student aide to complete the job alone as "x" minutes.

According to the given information, the teacher can assemble and staple the newsletter three times faster than the student aide. Therefore, the teacher's time to complete the job alone is "x/3" minutes.

When they work together, their combined work rate is the sum of their individual work rates. We can express this as:

1/x + 1/(x/3) = 1/21

To simplify the equation, we can multiply through by the least common multiple (LCM) of the denominators,

which is 3x:

3 + 3/x = x/(21x)

Multiplying both sides of the equation by 21x:

63x + 63 = x^2

Rearranging the equation:

x^2 - 63x - 63 = 0

Now we can solve this quadratic equation for "x" using factoring, completing the square, or the quadratic formula.

Factoring is not straightforward in this case, so let's solve it using the quadratic formula:

x = (-(-63) ± sqrt((-63)^2 - 4(1)(-63))) / (2(1))

Simplifying:

x = (63 ± sqrt(3969 + 252)) / 2

x = (63 ± sqrt(4221)) / 2

Now, calculating the square root:

x ≈ (63 ± 64.98) / 2

We have two possible solutions:

x ≈ (63 + 64.98) / 2 ≈ 128.98 / 2 ≈ 64.49

or

x ≈ (63 - 64.98) / 2 ≈ -1.98 / 2 ≈ -0.99

Since time cannot be negative, we discard the negative solution.

Therefore, it would take the student aide approximately 64.49 minutes to complete the job alone, and the teacher, who is three times faster, would take approximately 21.50 minutes (64.49/3) to complete the job alone.

Equilibrium is the term refers to coordination, balance, and balance in three dimensional space.

The equilibrium condition of an object exists when Newton's first law is valid. An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

There are three types of equilibrium: stable, unstable, and neutral.

The equation that represents the line passing through the point (2, -5) with a slope of -3 is y = -3x + 1.

The equation of a line can be represented in the slope-intercept form, which is y = mx + b. In this form, "m" represents the slope of the line and "b" represents the y-intercept.

Given that the line passes through the point (2, -5) and has a slope of -3, we can substitute these values into the slope-intercept form to find the equation of the line.

The slope-intercept form is y = mx + b. Substituting the slope of -3, we have y = -3x + b.

To find the value of "b", we can substitute the coordinates of the point (2, -5) into the equation and solve for "b".

-5 = -3(2) + b

-5 = -6 + b

b = -5 + 6

b = 1

Now that we have the value of "b", we can substitute it back into the equation to find the final equation of the line.

y = -3x + 1

Therefore, the equation that represents the line passing through the point (2, -5) with a slope of -3 is y = -3x + 1.

The device that indicates whether two AC sources to be connected in parallel are in the correct phase relationship is called a synchronizing device.

A synchronizing device is a mechanism that ensures that two AC sources are in sync when they are connected in parallel. It's used to match the voltage, frequency, and phase angle of two alternating current (AC) sources.

It guarantees that the power supplied by both generators is synchronized, allowing them to be combined into a single electrical system without disrupting the balance of the current or causing a short circuit.

As a result, it is critical to the safe and efficient operation of power systems. A phase sequence indicator (PSI) or a synchroscope is often used as a synchronizing device. It works by providing an indication of the voltage difference, the phase angle difference, and the frequency difference between two AC sources that are to be synchronized.

Therefore, a synchronizing device is an instrument that determines whether two alternating current (AC) sources to be connected in parallel are in the appropriate phase relationship.

AB and CD are not parallel. The answer is that AB is not parallel to CD.

Given, A C=7, B D=10.5, B E=22.5 , and A E=15

To determine whether AB || CD, let's use the converse of the corresponding angles theorem. In converse of the corresponding angles theorem, it is given that if two lines are cut by a transversal and the corresponding angles are congruent, then the two lines are parallel.

In this case, let's consider ∠AEB and ∠DEC. It is given that A E=15 and B E=22.5.

Therefore, AE/EB = 15/22.5 = 2/3

Let's find CE. According to the triangle inequality theorem, the sum of the length of two sides of a triangle is greater than the length of the third side.AC + CE > AE7 + CE > 15CE > 8

Similarly, BD + DE > BE10.5 + DE > 22.5DE > 12Also, according to the triangle inequality theorem, the sum of the length of two sides of a triangle is greater than the length of the third side.AD = AC + CD + DE7 + CD + 12 > 10.5CD > 10.5 - 7 - 12CD > -8.5CD > -17/2

So, we have AC = 7 and CD > -17/2. Therefore, ∠AEB = ∠DEC. But CD > -17/2 which is greater than 7.

Thus, AB and CD are not parallel. Hence, the answer is that AB is not parallel to CD.

Bro math Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

Let Dawn’s monthly allowance be 5x. Let Evelyn’s monthly allowance then be 8x.

Percentage increase by 20% is the same as multiplying a number by 1.2

To find the percentage decrease of Evelyn’s monthly allowance, we can equate their allowances after the change of their initial allowance.

1.2 * 5x = k/100 * 8x

k represents the percentage

6x = 8xk/100

Cancel the x’s from both sides

6 = 8k/100

600 = 8k

k = 75

Therefore since 75% of Evelyn’s monthly allowance is equal to Dawn’s increased monthly allowance, this means Evelyn’s monthly allowance was decreased by 25%.

Your monthly payment for the 60-month, 5.54% APR motorcycle loan to purchase your dream Harley-Davidson will be $136.88.

To calculate the monthly payment for a motorcycle loan, we can use the formula for the present value of an annuity. The formula is:

PMT = PV * r / (1 - (1 + r)^(-n))

Where:
PMT = Monthly payment
PV = Present value of the loan
r = Monthly interest rate
n = Number of months

In this case, the present value of the loan (PV) is $7,200, the monthly interest rate (r) is 5.54% divided by 12 (0.0554 / 12), and the number of months (n) is 60.

Plugging in these values into the formula, we get:

PMT = 7200 * (0.0554 / 12) / (1 - (1 + (0.0554 / 12))^(-60))

Evaluating this expression, the monthly payment comes out to be approximately $136.88.

Therefore, your monthly payment for the 60-month, 5.54% APR motorcycle loan to purchase your dream Harley-Davidson will be $136.88.
