<span>Need to write a decimal which is the value is 1/10 as much as the value of the other digit.
=> 1/10 is equals to 0.1
Thus, we need to find a decimal that the value of the digits are 1.10 greater than each other.
Since we have 0.1 already as decimals, simply divide 0.1 again with 10 to get the answer
=> 0.1 / 10
=> 0.01
Now, let’s add the 0.1 and 0.01
=> 0.11
Thus, the decimal that are 1/10 greater than the other digit next to it is 0.11.

solve the problem related to population growth.A city had a population of 23,900 in 2007 and a population of 25,100 in 2012.(a)
Finger [1]

Solution

a)

To find the exponential growth function, we apply the exponential growth formula which is

N(t)=a(1+k)^t

Where

\begin{gathered} a\text{ is the }initial\text{ population} \\ k\text{ is the growth rate} \\ t\text{ is the number of time intervals} \end{gathered}

Given that

\begin{gathered} a=23,900 \\ N(5)=25,100 \\ t=2012-2007=5 \end{gathered}

Substitute the variables into the exponential growth formula

\begin{gathered} 25100=23900(1+k)^5 \\ \text{Divide both sides by 23,900} \\ \frac{25100}{23900}=\frac{23900(1+k)^5}{23900} \\ 1.05021=(1+k)^5^{} \\ \sqrt[5]{1.05021}=1+k \\ 1.00984=1+k \\ \text{Collect like terms} \\ k=1.00984-1 \\ k=0.00984 \end{gathered}

Hence, the exponential growth function is

\begin{gathered} N(t)=23900(1+0.00984)^t_{} \\ N(t)=23900(1.00984)^t \end{gathered}

Hence, the exponential growth function is

N(t)=23900(1.00984)^t

b)

For the population of the city in 2022,

\begin{gathered} t=2022-2007=15 \\ t=15 \end{gathered}

Substitute for t into the exponential growth function

\begin{gathered} N(t)=23900(1.00984)^t \\ N(15)=23900(1.00984)^{15} \\ N(15)=27700\text{ (nearest hundred)} \end{gathered}

Hence, the population is 2022 is 27700 (nearest hundred)

Solve for x . x + 30 divided by 11 equals 1
Mnenie [13.5K]
What you are asking is x + 30 ÷ 11 = 1

x + 30 ÷ 11 = 1
Simplify
x + 30/11 = 1

Subtract 30/11 from each side
x + 30/11 - 30/11 = 1 - 30/11
x = -19/11
