Answer:

The standard time for this task is 162 seconds ⇒ 1st answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Kat observed one of her workers perform this task six times, with the

 following results

- Observation : 1       2      3      4      5      6

 Time (sec.)    : 99   87    90    81    93    90

- Lets calculate the average of the time

∵ The average time = Total time ÷ number of times

∵ Total = 99 + 87 + 90 + 81 + 93 + 90 = 540

∵ The number of times is 6

∴ The average time = 540 ÷ 6 = 90 seconds

- The standard time = normal time + allowances

∵ Normal time = average time × rating

∵ The average time is 90 seconds

∵ The rate is 50 percent faster pace than average

∴ The rate is (1 + 50/100) = 1.5

∴ The normal time = 90 × 1.5 = 135 seconds

- The allowance of 20 percent of job time is used

∵ The allowance = average time × allowance rate

∵ The allowance is 20%

∴ The allowance = 135 × 20/100 = 135 × 0.2 = 27 seconds

* Lets calculate the standard time

∵ The standard time = normal time + allowances

∵ the normal time is 135 seconds

∵ The allowance time is 27 seconds

∴ The standard time = 135 + 27 = 162 seconds

* The standard time for this task is 162 seconds

Scenario
Elena-2011 [213]

The function that gives the shares received by a post whereby each friend

shares the post a constant multiple of times each day is exponential.

<h3>Responses;</h3>
  • Ben's social media post: <u>2 × 3ⁿ</u>
  • Carter's social media post: <u>10 × 2ⁿ</u>

<h3>Methods by which the above expressions are obtained:</h3><h3 /><h3>Ben's social media posts;</h3><h3 /><h3>Given:</h3>

The given table of values for Ben's social media post is presented as follows;

\begin{tabular}{|c|c|}Day&Number of shares\\0&2\\1&6\\2&18\end{array}\right]

<h3>Solution:</h3>

The number of shares triples everyday, therefore, the number of shares form a geometric progression, with a common ratio of r = 3, and a first term of <em>a</em> = 2

The function for the number of shares of Ben's post is, tₙ  = a·rⁿ

Which gives;

  • Ben's social media post shares on day <u><em>tₙ</em></u><u> = 2·3ⁿ</u>

<h3>Carter's social media posts;</h3><h3 /><h3>Given;</h3>

Number of friends Carter shared his post with = 10 friends

Number of people each of the 10 friends shared with each day = 2 people

<h3>Solution;</h3>

The exponential function for number of shares received by Carter is therefore, <u>tₙ = </u><u>10×2ⁿ</u>

  • Carter's social media post shares on day <em>n</em>: <u>10 × 2ⁿ</u>

Zack’s car travels 30.2 miles in 2/3 of an hour. What is the average speed, in miles per hour, of the car?
diamong [38]

Answer:

Step-by-step explanation:

30.2 miles / 2/3 hour

This is saying 30.2 divided by 2/3. When you divide by a fraction you have to multiply by the inverse

30.2 x 3/2

90.6 / 2

45.3 miles per hour
