Answer:

yes I can help you. the answer to the problem is 4/35.

Step-by-step explanation:

1. convert any mixed number into fractions.

your equation becomes 4/7÷5/1. this equals 4×1 over 7×5. multiply normally and your result is 4/35

The prime factorization of the number 21 is:

21 = 3*7

We want to write the prime factorization of 21.

To do so, we just need to divide the number by prime numbers.

The first prime number we can try is 2, if we divide by 2 we get:

21/2 = 10.5

This is not an integer, so 2 is not a factor.

The next one is 3:

21/3 = 7

Now we can rewrite:

21 = 3*7

Where 3 and 7 are prime numbers, so that is the prime factorization.

The polar coordinates for the point (-3, 3) are (3√2, -π/4).

The different polar coordinates for the same point (-3, 3) can be expressed as (3√2, 7π/4), (3√2, -π/4 + 2π), (3√2, -π/4 - 2π), and so on.

Here, we have,

To find the Cartesian coordinates (x, y) from the polar coordinates (r, θ), we can use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

Let's apply these formulas to the given polar coordinates (6, 3π/2):

x = 6 * cos(3π/2)

= 6 * 0

= 0

y = 6 * sin(3π/2)

= 6 * (-1)

= -6

Therefore, the Cartesian coordinates of the point with polar coordinates (6, 3π/2) are (0, -6).

Now, let's find the polar coordinates for the point (-3, 3) given in Cartesian coordinates. We can use the inverse trigonometric functions to find the angle:

r = √(x² + y²)

= √((-3)² + 3²)

= √(9 + 9)

= √18

= 3√2

θ = atan2(y, x)

= atan2(3, -3)

= atan(-1)

= -π/4

Therefore, the polar coordinates for the point (-3, 3) are (3√2, -π/4).

There are infinitely many possible polar coordinates for a given point in the Cartesian plane, as angles can be represented in different ways.

In this case, we can represent the angle -π/4 as 7π/4, -π/4 + 2π, -π/4 - 2π, and so on.

So, different polar coordinates for the same point (-3, 3) can be expressed as (3√2, 7π/4), (3√2, -π/4 + 2π), (3√2, -π/4 - 2π), and so on.

Answer:

y = –4x–10

Step-by-step explanation:

First write the equation of a straight line: y=mx+c

Using the coordinate given, x = –4 and y = 6. m = –4.

Substitute these values into the equation and solve for c.

6 = (–4×–4) + c

6 = 16 + c

subtract 16 from both sides

–10 = c

now write the full equation using c.

y = –4x+–10

Mary's HLV is $2,215,773.95.

Mary's HLV if she works until 70 is $1,611,008.23.

Mary's COE if she works until 75 is $5,130,372.40.

Mary's COE if she works until 70 is $2,985,308.60.

To calculate the Human Life Value insurance (HLV) of Mary, we need to determine the present value of her future income stream.

Annual after-tax earnings = $55,000 x (1 - 0.15) = $46,750

Total after-tax earnings over working life = $46,750 x (1 + 0.03)^(75-35) = $3,382,820.33

Total personal consumption = 27% x $3,382,820.33 = $914,073.89

Calculate Mary's HLV:

= $3,382,820.33 - (1 + 0.05)^(-1) x $914,073.89

= $2,215,773.95

Therefore, Mary's HLV is $2,215,773.95.

If Mary works until 70 total after-tax  = $46,750 x (1 + 0.03)^(70-35) = $2,124,182.09

Mary's HLV if she works until 70 is $1,611,008.23.

To calculate the Capitalization of Earnings (COE) method. Here's how we can calculate it:

Calculate Mary's expected earnings in her final year of work:

Expected earnings in final year = $55,000 x (1 + 0.03)^(75-35) = $256,518.62

Apply a capitalization rate to the expected earnings:

COE = expected earnings in final year / capitalization rate

= $256,518.62 / 0.05

= $5,130,372.40

Therefore, Mary's COE if she works until 75 is $5,130,372.40.

If Mary works until 70, her expected earnings in her final year of work would be:

Expected earnings in final year = $55,000 x (1 + 0.03)^(70-35) = $149,265.43

Mary's COE if she works until 70 is $2,985,308.60.

Using leaner equation we find that After 12 years from now will Jerry's age be (2/3) of the combined ages of his brother and sister at that time.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Let Jerry's brother present age be X years,

Then Jerry's present age will be 2x

And his sister's present age will be 2X - 6

And let y be  the  number of years from now when Jerry's age = (2/3) of combined age of his brother and sister.

So we have that,

(2X + y)  = (2/3) [(X + y) + (2X - 6 + x)]

simplify the above equation

2X + y = (2/3) [3X + 2y - 6]

multiply through by 3/2

3X + (3/2)y = 3X + 2y - 6

subtract  3X from both sides

(3/2)y = 2y - 6

subtract 2y from both sides

-1/2y = -6

divide both sides by -1/2

y = 12 years

Step-by-step explanation:

Extra people required is 50.

Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Question 1 :

Number of associates = 30

Number of direct workers = 30 - 2 = 28

You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.

Direct rate = 150 units per hour

Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week

                                                            = 37.5 hours per week

Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units

28 people produce 5625 units in a week

Let x people produce 10,000 + 5625 = 15,625 units in a week

Using proportion,

28 : 5625 = x : 15,625

28 / 5625 = x / 15,625

x = (28 × 15,625) / 5625 = 77.78 ≈ 78

Extra people required = 78 - 28 = 50

Question 2 :

Number of sandwiches made in 10 minutes = 1

Number of sandwiches made in 10 hours = 60

5 workers are there. one worker makes 60/5 = 12 sandwiches

But Deli want number of sandwiches in 10 hours = 75

One worker should make 75/5 = 15 sandwiches instead of 12.

Number of sandwiches made in 8 minutes should be 1.

So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.

Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

Approximately \(30\; \rm N\) toward the center of the object.

Step-by-step explanation:

Look up the gravitational constant and the mass of the earth:

\(\begin{aligned}G &\approx 6.67 \times 10^{-11}\; \rm m^{3} \cdot kg^{-1} \cdot s^{-2} \\ &= 6.67 \times 10^{-11} \; \rm N \cdot m^{2} \cdot kg^{-2}\end{aligned}\).

\(M \approx 5.97 \times 10^{24}\; \rm kg\).

Convert the unit of distance to standard units:

\(\begin{aligned}r &= 25600\; \rm km \\ &= (25600 \times 10^{3})\; \rm m \\ &= 2.56 \times 10^{7}\; \rm m\end{aligned}\).

Consider two spherical objects with mass \(m_{1}\) and \(m_{2}\). Let \(r\) denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:

\(\begin{aligned}F &= \frac{G \cdot m_{1} \cdot m_{2}}{r^{2}}\end{aligned}\).

Thus, the size of the gravitational force between this object and the earth would be:

\(\begin{aligned}F &= \frac{G \cdot m \cdot M}{r^{2}} \\ &\approx \frac{1}{2.56\times 10^{7}\; \rm m} \\ &\quad \times 6.67 \times 10^{-11}\; \rm N \cdot m^{2}\cdot kg^{-2} \\ &\quad \times 50\; \rm kg \times 5.97 \times 10^{24}\; \rm kg \\ &\approx 30\; \rm N\end{aligned}\).

Since gravitational force is attractive, the \(50\; \rm kg\) object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this \(50\; \rm kg\!\) object.

Step-by-step explanation:

Therefore, the probability of getting exactly 4 calls between 8:00 AM and 9:00 AM is approximately 0.1755, rounded to four decimal places.

To calculate the probability of getting exactly 4 calls between 8:00 AM and 9:00 AM, we need to use the Poisson distribution formula. The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space. In this case, the mean (λ) is given as 5. The formula for the Poisson distribution is:

P(X = k) = (e*(-λ) * λ\(^k\)) / k!

Where:

P(X = k) is the probability of getting exactly k calls

e is the base of the natural logarithm (approximately 2.71828)

λ is the mean number of calls (given as 5)

k is the number of calls (in this case, 4)

k! is the factorial of k

Let's calculate the probability using the formula:

P(X = 4) = (e*(-5) * 5⁴) / 4!

P(X = 4) ≈ 0.1755
