Meagan walked 4/10 mile to the park.she walked the same distance home.how much did she walk altogether? Write in simplest form

We add them up to find the total distance :

$\dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5}$

$\text {She walked } \dfrac{4}{5} \text { miles}$

The population of Henderson City was 3,381,000 in 1994, and is growing at an annual rate 1.8%

liq [111]

<h2>In the year 2000, population will be 3,762,979 approximately. Population will double by the year 2033.</h2>

Step-by-step explanation:

Given that the population grows every year at the same rate( 1.8% ), we can model the population similar to a compound Interest problem.

From 1994, every subsequent year the new population is obtained by multiplying the previous years' population by $\frac{100+1.8}{100}$ = $\frac{101.8}{100}$ .

So, the population in the year t can be given by $P(t)=3,381,000\textrm{x}(\frac{101.8}{100})^{(t-1994)}$

Population in the year 2000 = $3,381,000\textrm{x}(\frac{101.8}{100})^{6}$ = $3,762,979.38$

Population in year 2000 = 3,762,979

Let us assume population doubles by year $y$ .

$2\textrm{x}(3,381,000)=(3,381,000)\textrm{x}(\frac{101.8}{100})^{(y-1994)}$

$log_{10}2=(y-1994)log_{10}(\frac{101.8}{100})$

$y-1994=\frac{log_{10}2}{log_{10}1.018}=38.8537$

$y$ ≈ $2033$

∴ By 2033, the population doubles.

How to I find the estimate of 25% of 230

MArishka [77]

The key to understanding the question is to keep the details at the fore.

Percentage = 25%

Amount = 230

Our answer to the estimation is given by the formula:

$\begin{gathered} \text{Percentage }\cdot\text{ Amount = 25\% }\cdot\text{ 230} \\ =\frac{25}{100}\cdot230=\frac{25\cdot230}{100} \\ =57.5 \end{gathered}$
