The common difference is -1-(-7) = 6. Since each term is 6 more than the last, the sequence is described by
  a(1) = -7
  a(n) = a(n-1) + 6
. . . n ≥ 2

Answer:

a_{n}= a_{n-1} + 6

Step-by-step explanation:

–7, –1, 5, 11, ......

LEts find out the difference

-1-(-7)= 6

5-(-1)= 6

11 - 5=6

So common difference is 6

General form of recursive for arithmetic sequence is

a_{n}= a_{n-1} + d where d is the common difference

we know common difference d= 6

a_n-1 is the previous term , an is the next term

Recursive formula is 4

a_{n}= a_{n-1} + 6

olya-2409 [2.1K]

Answer:

<em>$605</em>

<em></em>

Step-by-step explanation:

The correct question is

Taho Earns His Regular Pay Of $11 Per Hour For Up To 40 Hours Of Work Per Week. For each hour over 40 hours of work per week. Taho earns 1½ times his regular pay. How much does Taho earn in a week in which he works 50 hours?

a. $550

b. $605

c. $625

d. $750

e. $825

For the first $40 that Taho works, he earns $11 x 40 = $440

For the extra $10 (since he worked 50 hrs that week)

1½ of $11 per hr = 1.5 x $11 = $16.5

for the 10 days extra = $16.5 x 10 = $165

total pay = $440 + $165 = <em>$605</em>

Convert a markup of 15% on selling price to its equivalent markup on cost.
spayn [35]

Answer:

option: D is correct. (  (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).

Step-by-step explanation:

" Markup is the percentage difference between a product's cost and its selling price "

Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.

As there is a markup of  15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.

<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>

<em>Hence, option D is true.</em>

Week 1 = 8 13/15 in.
Week 2 = 9 8/15 in.
Week 3 = 10 1/5 in.
Week 4 = 10 13/15 in.
Week 5 = 11 8/15 in.

Lyric:
Week 0 = 10 7/10 in.
Week 1 = 10 13/15 in.
Week 2 = 11 1/30 in.
Week 3 = 11 1/5 in.
