Answer:

7.5

Step-by-step explanation:

Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:

Hours        Dollars

0                 25 = 25 + 0(20)=25

1                  25+20 = 25 + 1(20)=45

2                  25+20+20 = 25 +2 (20)=65

3                  25+20+20+20 = 25 +3 (20)=85

4                  25+20+20+20+20 = 25 +4 (20)=105

5                  25+20+20+20+20+20 = 25 +5 (20)=125

......

n                  25+n(20)=175

To find how many hours he worked for $175 we solve the equation using inverse operations:

25+n(20)=175

25-25+n(20)=175-25

n(20)=150

n= 7.5 hours

Answer:

Ronnie spent 5 hours working.

Step-by-step explanation:

From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:

c=25+30x, where:

c is the total cost of the job

x is the number of hours

Now, you can replace c with 175 and solve for x:

175=25+30x

175-25=30x

150=30x

x=150/30

x=5

According to this, the answer is that Ronnie spent 5 hours working.

NEED HELP WITH A MATH QUESTION
Lady_Fox [76]

Answer:

\dfrac{18}{5}

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

\dfrac{18}{5}

Peter Chibwe works at Company XYZ. The following information relates to his performance at work for a single week Deductions are
Colt1911 [192]

The question is related to Payroll Administration and Management.

Where the weekly gross is $10,000 the Net Pay is $ 7,240 while monthly Net Pay is $ 28,960.00.

<h3>What is Payroll Administration?</h3>

This is defined as the series of task required to organize the compensation an benefits of the employee for the period that they have spent working.

<h3>The solution is given below:</h3>

A) Note that the information given above is for a week. We are not given the gross wage. Hence we'd assume that the gross wage for the week is $10,000.

If gross pay is $10,000, Net Pay is calculated by removing deductions.

Deductions are:

Pension fund = 7.5% of 10,000 = $750

PAYE Tax = 20% of (95% of 10,000) = $1,900 This is because medical aid is non-taxable.

Employee Insurance = 1% of 10,000 = $100

Union Membership = $10

The Total Deduction thus is = 750 + 1,900 + 100 +10 = $2, 760.00

The Net pay =  Gross Pay Less Deductibles

= 10,000-7,760

Thus The Net pay = $ 7,240/Week.

His weekly net wage will be:

7,240 * 4 = $28,960.00/Month

B) The kind of remuneration method used by company XYZ is

Time Rate System. Under the time rate system, the worker is paid per hour, per day, per week, or per month.

It is normally used for workers who are engaged on highly skilled jobs or highly skilled services, for example, equipment testing, or inspection of operations, toolmaking, etc.

Ilya [14]
<span>Juanita is watering her lawn using the water that is stored by rainwater.
=> the water in the tank drops 1/3 inch in every 10 minutes she waters.
=> The tanks water level is 4 feet.
Question : Number of days can Juanita waters is she waters 15 minutes per day.
=> 4 feet is the total amount of water = 1 ft = 12 inches
=> 48 inches in total
=> 1/3 inch is used every 10 minutes = 0.33 inches
=> she waters 15 minutes per day = 0.495 inches in every 15 minutes
Solution
=> 48 inches / 0.495 inches per day
=> 96.97
So Juanita can use all the water in water tank for approximately 97 days.</span>
