Answer:

Step-by-step explanation:

$\dfrac{5}{2}=d-\dfrac{2}{4}\qquad\left/\dfrac{2}{4}=\dfrac{2:2}{4:2}=\dfrac{1}{2}\right/\\\\\dfrac{5}{2}=d-\dfrac{1}{2}\qquad\text{add}\ \dfrac{1}{2}\ \text{to both sides}\\\\\dfrac{5}{2}+\dfrac{1}{2}=d-\dfrac{1}{2}+\dfrac{1}{2}\\\\\dfrac{5+1}{2}=d\\\\\dfrac{6}{2}=d\to d=3$

Two students were asked to find the value of a $1000 item after 3 years. The item was depreciating (losing value) at a rate of 4

Yuki888 [10]

Answer:

Student 2 is incorrect because he didn't use the formula properly

Step-by-step explanation:

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

$C(3)=\$1000\cdot(1-0.4)^3$

$C(3)=\$1000\cdot0.6^3$

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly

Converting repeating decimals to a fraction

Goshia [24]

Step-by-step explanation:

Step 1:

Let x equal the repeating decimal you are trying to convert to a fraction.

Step 2:

Examine the repeating decimal to find the repeating digit(s).

Step 3:

Place the repeating digit(s) to the left of the decimal point.

Step 4:

Place the repeating digit(s) to the right of the decimal point.

Step 5:

Using the two equations you found in step 3 and step 4, subtract the left sides of the two equations. Then, subtract the right sides of the two equations

As you subtract, just make sure that the difference is positive for both sides.
