9. Large postcards come in packages of 20. Small postcards come in packages of 25. A store buys 24 packages of large postcards and 18 packages of small postcards. Which statement is true? * 10 points The store bought a total of 930 postcards The store bought 30 more small postcards than large postcards The store bought a total of 932 postcards. The store bought 68 more large postcards than small postcards.

930 packages.

Step-by-step explanation:

Large postcards come in packages of 20.

Small postcards come in packages of 25.

A store buys 24 packages of large postcards. The total packages will then be:

= 20 × 24 = 480

The store buys 18 packages of small postcards. The total package here will be:

= 18 × 25 = 450

Therefore, total packages bought will be:

= 480 + 450

= 930 packages

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

i believe the answer is the polygon, heptagon.
