Acertain colony of bacteria doubles in size every 5 minutes if the colony began with two organisms how many will there be after 30 minutes

There will be 128 organisms after 30 minutes.

Step-by-step explanation:

30/5=6

1.) 2*2=4

2.) 4*2=8

3.) 8*2=16

4.) 16*2=32

5.) 32*2=64

6.) 64*2=128

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
