Answer:

Equivalent. 0.4(k+3)=0.4k+1.2

Step-by-step explanation:

x means multiplication. k is the variable.

Hi.

So, you have to distribute the 0.4 into the parenthesis to get rid of them. So, you do 0.4xk, which is just 0.4k, and 0.4x3, which is 1.2. So, you have 0.4k+1.2, which means it is Equivalent.

What is 4 1/3 × 2 3/5? express it in lowest terms​
soldier1979 [14.2K]

We have,

4\dfrac{1}{3}\cdot2\dfrac{3}{5}=\dfrac{13}{3}\cdot\dfrac{13}{5}=\dfrac{13\cdot13}{3\cdot5}=\dfrac{169}{15}=\boxed{11.2\bar{6}}

To express periodic number calculated we use:

x=11.2\bar{6}\\10x = 112.\bar{6}\\100x=1126.\bar{6}\\90x=100x-10x\Longrightarrow90x=1126.\bar6-112.\bar6\\90x=1014\\x=\dfrac{1014}{90}=\boxed{11\dfrac{24}{90}}

Hope this helps.

Answer:

$9,220,000(0.888)^t

Step-by-step explanation:

Model this using the following formula:

Value = (Present Value)*(1 - rate of decay)^(number of years)

Here, Value after t years = $9,220,000(1 -0.112)^t

          Value after t years =  $9,220,000(0.888)^t
