The ratio x : y is equal to 2 : 5, and y is 80% of z. Write an equation to represent the proportional relationship between x and
Mila [183]

Answer:

  • x : z = 8 : 25

Step-by-step explanation:

<u>Given</u>

  • x : y = 2 : 5, y is 80% of z

<u>Rearranging the ratios:</u>

  • x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5x
  • y is 80% of z ⇒ y = 0.8z

<u>Comparing the values of y:</u>

  • 2.5x = 0.8z
  • x/z = 0.8/2.5
  • x/z = 0.32
  • x/z = 32/100
  • x/z =  8/25
  • x : z = 8 : 25

3. A new house was purchased in 1990 for $175,000.
brilliants [131]
<h3>Answer:   $655,430.67</h3>

===============================================

Work Shown:

A = P*(1+r)^t\\\\A = 175,000*(1+0.045)^{30}\\\\A = 175,000*(1.045)^{30}\\\\A \approx 175,000*3.74531813453687\\\\A \approx 655,430.673543952\\\\A \approx 655,430.67\\\\

The home's value in 2020 is approximately $655,430.67 assuming that the rate of inflation is kept at 4.5% per year.

Note that for the r value, I used the decimal form of 4.5% (so you'll move the decimal point 2 spots to the left).

Also, the timespan from 1990 to 2020 is 2020-1990 = 30 years, which is why I used this for the t value.
