The number of bacteria multiplies by two every hour

For example,

1 times 2 = 2,

then 2 times 2 = 4,

next 4 times 2 = 8

And so on and so forth

so look at the last number of bactieria they gave you (128) and multiply that by 2 so that would equal 256

so then multiply that by 2 so that would equal 512

512 (2) = 1024

1024 (2) = 2048

2048 (2) = 4096

4096(2) = 8192

8192 (2) =16384

16384 (2) = 32768

So the number of bacteria after 15 hours would be 32768

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
