B. 2 time 2 is 4 , 4 times two is 8, 8 times five is 40
Answer:
The time it will take the population to grow to 800 insects is 17 days.
Step-by-step explanation:
The growth function of the insects is exponential.
The exponential growth function is:

Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time taken
It is provided that there were 270 insects after 9 days and initially there were 80 insects.
Compute the value of <em>r</em> as follows:

Now, compute the time it will take the population to grow to 800 insects as follows:

Thus, the time it will take the population to grow to 800 insects is 17 days.
Answer: b = 2a
Step-by-step explanation:
<u>Original equation</u>
a = (1/2) b
<u>Multiply 2 on both sides</u>
a * 2 = (1/2) b * 2

Answer:
5 hours
Step-by-step explanation:
Our goal here is 3 F because 82+3=85
Ok so you start at 82. For example, you can do 0.6×1=0.6 (no)
0.6×2=1.2 (no)
0.6×3=1.8 (no)
0.6×4=2.4 (no)
0.6×5=3 (yes)
82°+3°=85°
