A single tree produces about 2.6 × 10² lb of oxygen each year. The Amazon rainforest has about 3.9 X 10^11 trees.

Ymorist [56]

$(2.6\times10^2) \times (3.9\times10^{11}) = 1.014\times10^{14}$

$1.014\times10^{14}$ <---How much is produced by all the trees in a year.
They want how much each day so divide by 365

$\frac{1.014\times10^{14}}{365} = 2.77808\times10^{11}$
$2.77808\times10^{11}$ <---answer per day

The groundhog population of Punxsutawny, Pennsylvania is closely monitored each year. Two years ago the population decreased by

kap26 [50]

Answer:

There was a increase of 1.7% over these three years

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

What was the percentage increase/decrease of groundhogs over these three years?

Decrease of 12%(multiplication by 0.88).

Increase of 6%(multiplication by 1.06).

Increase of 9%(multiplication by 1.09).

After these three years:

0.88*1.06*1.09 = 1.017

1.017 - 1 = 0.017

0.017*100% = 1.7%

There was a increase of 1.7% over these three years

Select the three ratios that represent the number of red cars to blue cars.

Lorico [155]

Three ratios that represent the number of red cars to blue cars are

2 : 3

6 : 9

8 : 12

$\texttt{ }$

<h3>Further explanation</h3>

<u>Given:</u>

Number of Red Cars = 4

Number of Blue Cars = 6

<u>Asked:</u>

Ratio = ?

<u>Solution:</u>

<em>Let:</em>

<em>Number of Red Cars = R</em>

<em>Number of Blue Cars = B</em>

The ratio that represent the number of red cars to blue cars is :

$R : B = 4 : 6$

We can find other ratio by dividing or multiplying the above comparison with the same number :

$R : B = (4/2) : (6/2) = 2 : 3$

$R : B = (4 \times 2) : (6 \times 2) = 8 : 12$

$R : B = (4 \times \frac{3}{2}) : (6 \times \frac{3}{2}) = 6 : 9$

$\texttt{ }$

<h3>Conclusion:</h3>

Three ratios that represent the number of red cars to blue cars are:

2 : 3

6 : 9

8 : 12
