If they are growing 80% for every twodays, it would be 40% for every one day.

Bacteria after 9 days = 212 * 9 * 40 / 100
= 763.2
To round up, the population of bacteria after 9 days would be 763, with a growth rate of 80% for every two days.

A rectangular box has a volume x^3-64 cubic inches. If the height of the box x-4 inches, what is the area of the base of the box
Zanzabum

Answer:

\purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

Step-by-step explanation:

\because \: V_{box} = A_{base} \times height  \\  \\ \therefore \: A_{base} =  \frac{V_{box}}{height}  \\  \\ \therefore \: A_{base} =  \frac{ {x}^{3}  - 64}{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ {x}^{3}  -  {4}^{3} }{(x - 4)}   \\  \\  \therefore \: A_{base} =  \frac{ \cancel{ ({x}  -  {4})}( {x}^{2}  + 4x +  {4}^{2}  )}{\cancel{ ({x}  -  {4})}}  \\  \\ \purple{ \bold{ \therefore \: A_{base} = {x}^{2}  + 4x +  16}}

Find the value of x. (picture)
Hoochie [10]

Answer:

x = 23

Step-by-step explanation:

Remember, angles in a triangle add up to equal 180

That being said we can create an equation to solve for x

180 = 110 + 35 + x + 12

now we solve for x

step 1: combine like terms

110 + 35 + 12 = 157

now we have 180 = 157 + x

step 2 subtract 157 from each side

180 - 157 = 23

157  - 157 cancels out

we're left with x = 23
