It is observed that a certain bacteria culture has a relative growth rate of 15% per hour, but in the presence of an antibiotic
wel

Answer: 110 in the presence of no antibiotic, 53 in the presence of an antibiotic

Step-by-step explanation:

So first we are told the growth rate of a bacteria culture is 15% and the number of bacteria in the culture is 24

So we find 15% of 24

15/100 x 24 = 18/5

So 18/5 bacteria is produced every hour, then for 24hours

18/5 x 24 = 86.4

The number of bacteria is already 24 as said

So altogether

86.4 + 24 = 110.4 approximately 110

Then, for the presence of antibiotic, the growth rate is 5%

So 5% of 24

5/100 x 24 = 6/5

So 6/5 bacteria is produced every hour

For 24hours

6/5 x 24 = 28.8

Initial culture = 24

Final culture = 24 + 38.8 = 52.8 approximately 53

#11 (Angles with Equations) In the figure below, 2POR is 180°.
lina2011 [118]

Answer:

55

Step-by-step explanation:

The three angles form a straight line, so they add to 180.

x + x + 70 = 180

Combine like terms

2x+70 =180

Subtract 70 from each side

2x+70-70 =180-70

2x= 110

Divide by 2

x = 55

SQT = x

So SQT = 55

KIM [24]

answer:

( \frac{1}{7}, 1)

explanation:

- 5y =  - 5 \\ 7x + 6y = 7 \\ divide \: both \: sides \: by \:  - 5 \\  \\ y = 1 \\  \\ 7x + 6y = 7 \\ substitute \: the \: value \: of \: y \: into \: an  \\ equation \\  \\ 7x + 6 \times 1 = 7 \\ multiply \: 6 \: to \: 1 \\  \\ 7x + 6 = 7 \\ subtract \: 6 \: from \: both \: sides \\  \\ 7x = 1 \\ divide \: both \: sides \: by \: 7 \\  \\ x =  \frac{1}{7} \\  \\  (\frac{1}{7}, 1)

What is the value of e^3x+6=8
Natasha2012 [34]

Hello there!

<u><em>Answer: ⇒⇒  x=\frac{2}{e^3}</em></u>

___________________________________________________

Step-by-step explanation:

First you had to subtract by 6 from both sides of equation.

e^3x+6-6=8-6

Simplify.

e^3x=2

Then you divide by e³ from both sides of equation.

\frac{e^3x}{e^3}=\frac{2}{e^3}

Simplify it should be the correct answer.

x=\frac{2}{e^3}
