in a wood there are 420 silver birch trees, 160 oak tees and 300 wild cherry trees. what is the percentage of the oak trees give
elena-14-01-66 [18.8K]

Answer:

18.2%

Step-by-step explanation:

The total number of trees in the wood = 420 + 160 + 300

                                                                = 880 trees

∴ The percentage of the oak trees = \frac{160}{880} * \frac{100}{1}

                                                            = \frac{2 * 100}{11}%

                                                            = \frac{200}{11}%

                                                            = 18.181818...%

In 1 decimal place = 18.2%

Hope this helps!!

Write an example of an equation that’s represents exponential decay
seropon [69]

The equation for exponential decay is given as y = a(1 - r)^x.

<u>Explanation:</u>

The formula for original exponential decay is y = ab^x.

The growth rate (r) is determined as b = 1 + r.

The decay rate (r) is determined as b = 1 - r.

y = ab^x (Where b = 1 - r)

y = a(1-r)^x

a represents the initial value

r represents growth or decay rate

x represents the number of time intervals that have passed.

<em>For example</em>

The population of Home Town is 2016 was estimated to be 35,000 people with an annual rate of increase of 2.4%.

The equation for decay factor y = 35000(1 - 0.024)^x

y = 35000(0.976). (where x = 1)
