What's the explicit formula for 5,10,15,20,25,30

vivado [14]

Answer:

$a_{n}$ = 5n

Step-by-step explanation:

There is a common difference d between consecutive terms

d = 10 - 5 = 15 - 10 = 20 - 15 = 25 - 20 = 30 - 25 = 5

This indicates the sequence is arithmetic with explicit formula

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 5 and d = 5 , then

$a_{n}$ = 5 + 5(n - 1) = 5 + 5n - 5 = 5n

Ms. Wilson invested $34000 in two accounts, one yielding 8% interest and the other yielding 9%. If she received a total of

Digiron [165]

Answer:

Amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000

Step-by-step explanation:

Total Amount = $ 34000

Let amount invested at 8 % rate = x

Amount invested at 9 % rate = $ 34000 - x

Total interest = $ 2910

$2910 = \frac{x (8) (1)}{100} + \frac{(34000-x) (9) (1)}{100}$

291000 = 8 x + 306000 - 9 x

x = 306000 - 291000

x = 15000

So amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000

John bought 3 pencils for $0.75 each and a notebook for $4.25. If the tax rate is 5%, what is the total amount of John's purchas

SIZIF [17.4K]

Answer:

$6.83

Step-by-step explanation:

First calculate the before-tax total amount:

$0.75 + $0.75 + $0.75 + $4.25, or

3($0.75) + $4.25 = $2.25 + $4.25 = $6.50 (total before tax)

The before-tax total PLUS the 5% tax comes to:

$6.50 + 0.05($6.50) = $6.50 + $0.33 = $6.83
