Answer:

The constant of proportionality is 5/3

Step-by-step explanation:

3 * k = 5

k = 5/3

Check

9 * k = 15

9 * 5/3 = 15

3*5 = 15

15 =15

The constant of proportionality is 5/3

Muriel can do the laundry in 3 hours working alone. Rea has more experience and can do the laundry in 2 hours working alone. How

vagabundo [1.1K]

Here we have a problem of rates of work, where we want to find the rate at which two people would work together, so we can find the time it takes to complete a given job when these two work together..

We will find that they need to work for 6/5 hours to do the laundry together.

---------------------------------------

We know that:

Muriel can do the laundry in 3 hours.
Rea can do the laundry in 2 hours.

<em>Then we can define:</em>

M = rate at which Muriel works = 1/3h
R = rate at which Rea works = 1/2h

Where the rates are computed as the quotient between 1 (1 total laundry completed) and the amount of time it takes to do it.

If they work together, the rate just adds up, so we will have:

rate = (M + R) = 1/3h + 1/2h

Now we need to write that as a single fraction, so we get:

rate = 1/3h + 1/2h = 2/6h + 3/6h = 5/6h

Now we can write an equation of the form:

rate*time = 1

Where the 1 again, means "one complete laundry done".

Then we have:

(5/6h)*T = 1

T = (6/5)h

This means that they need to work for (6/5) hours to do the laundry together.

No solution: 1/2y + 3.2 = 20, 15/2 + 2z -1/4 = 4z + 29/4 - 2z, 1.1 + 3/2x + 2 = 3.1 + 3/4x, and 4.5r = 3.2 + 4.5r. One solution: 2x + 4 = 3x + 1/2

The complete question is attached below.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

If the value of the variable is zero, then the no solution.

If the value of the variable is one, then the one solution.

If the value of the variable is infinity, then the infinite many solutions.

No solution: 1/2y + 3.2 = 20, 15/2 + 2z -1/4 = 4z + 29/4 - 2z, 1.1 + 3/2x + 2 = 3.1 + 3/4x, and 4.5r = 3.2 + 4.5r.

One solution: 2x + 4 = 3x + 1/2

3’2x (8-5) <br> 6’2+(4x3)<br> 42-(14-12)

mezya [45]

Answer:

1. 27

2. 48

3. 40

Step-by-step explanation:

3 to the power of 2 is 9 (3×3)

9×3=27. (8-5=3)

6 to the power of 2 is 36 (6×6)

36+12=48. (4×3=12)

42-2=40

Monthly rate = 1.25% Date Payments Purchases Balance Number of Days Product/Sum 9/1 - 9/5 $387.52 5 $1,937.60 9/6 $50.00 $337.52

ycow [4]

1. The average daily balance = $11,122.72 ÷ 30 = <u>$370.76</u>.

2. The Finance charge = monthly rate x average daily balance = <u>$4.63</u> ($370.76 x 1.25%).

3. The New balance = previous balance - payment/credits + finance charge + new purchases = <u>$404.41</u> ($387.52 - $50 + $4.63 + $62.26).

<h3>Data and Calculations:</h3>

Date Payments Purchases Balance Number of Days Product/Sum

9/1 - 9/5 $387.52 5 $1,937.60

9/6 $50.00 $337.52 1 $337.52

9/7 - 9/18 $337.52 12 $4,050.24

9/19 $62.26 $399.78 1 $399.78

9/20 - 9/30 $399.78 11 $4,397.58

Total $50.00 $62.26 30 $11,122.72

Thus, the new balance is $404.41 ($399.78 + $4.63).
