Equivalent ratios are those ratios which are same that is on simplifying each of them, we will get the same answer.

A. $\frac{2}{3} and \frac{9}{15} = \frac{3}{5}$

So they are not equivalent

B. $\frac{5}{8} and \frac{15}{21} = \frac{5}{7}$

So they are not equivalent

C. $\frac{3}{12} and \frac{6}{18} = \frac{1}{4} and \frac{1}{3}$

They are not equivalent too.

D. $\frac{4}{10} and \frac{12}{30} = \frac{2}{5} and \frac{2}{5}$

And they are equivalent. SO the correct option is D .

A particular bacterium population is found to double the in 20 minutes. If a laboratory culture

insens350 [35]

The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.

<h3>What does population growth exponentially mean?</h3>

When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.

Given:

P = 340

It has been discovered that a specific bacterial population doubles in 20 minutes.

k = 2/20 = 0.1

t = 37 minutes

We know that,

P = P₀ $e^{kt}$

340 = P₀( $e^{0.1*37}$ )

340 =P₀(40.44)

P₀ = 8.40

As a result, the bacteria that will be present in t=37 minutes is found to be 8.40 with no change in growth rate.

Answer:

Step-by-step explanation:

2)

x + 14 $\frac{13}{25}$ = -0.87

x + $\frac{363}{25}$ = - $\frac{87}{100}$

x + $\frac{1452}{100}$ = - $\frac{87}{100}$

x = - $\frac{87}{100}$ - $\frac{1452}{100}$

x = - $\frac{1539}{100}$

3)

x -8 $\frac{5}{6}$ = 1.5

x - $\frac{53}{6}$ = $\frac{9}{6}$

x = $\frac{9}{6}$ + $\frac{53}{6}$

x = $\frac{62}{6}$

x = $\frac{31}{3}$

4)

x - $\frac{7}{12}$ = - 7 $\frac{7}{16}$

x - $\frac{28}{48}$ = - $\frac{119}{16}$

x = - $\frac{357}{48}$ + $\frac{28}{48}$

x = - $\frac{329}{48}$

5)

$\frac{8}{9}$ - x = 6 $\frac{1}{15}$

$\frac{8}{9}$ = $\frac{91}{15}$ + x

$\frac{40}{45}$ - $\frac{273}{45}$ = x

- $\frac{233}{45}$ = x

x = - $\frac{233}{45}$

6)

-33.754 - x = 28.05

-33.754 - 28.05 = x

- 61.804 = x

x = - 61.804
