Suppose the first row of a specific section in an auditorium has 34 seats, row two has 38 seats, row three has 42 seats, etc. How many seats are in this section of the auditorium if there are a total of 20 rows? This is from the sequences and series unit. No work is needed but it is appreciated. Thank you if you help!

1,440

Step-by-step explanation:

a = 34

d = 38 - 34 = 4

S20 = (20/2)[2(34) + (20-1)(4)]

= 10(144)

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
