<em>Step-by-step explanation:</em>

<em></em>

<em>Here, the job is cleaning the house.</em>

<em></em>

<em>Mom does 1 job in 3 hours.</em>

<em></em>

<em>In 1 hour, mom does 1/3 of the job.</em>

If z varies inversely as x^2, and z = 9 when x = 2/3, find z when x = 5/4
zimovet [89]

Answer:

Step-by-step explanation:

z varies inversely

so z=a/x^2

9=a/(2/3)^2

9=a/(4/9)

9=9a/4

a=4

z=4/x^2

z=4/(5/4)^2

z=4/(25/16)

z=64/25

Chance bought a surf board for 249. Now it's on sale for 221.10. Find the percent of the discount
Masteriza [31]

<u>Answer:  </u>

Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.

<u>Solution: </u>

Step 1:

Bought price= RS.249

Sale price=RS.221.10

Step 2:

Discount = bought price - sales price

Discount = 249 - 221.10

Discount = 27.9

Step 3:

Discount Percent = \frac{\text {Discount}}{M R P} \times 100

Substitute the value for Discount which we found in step 2 in the above formulae

Discount Percent = \frac{27.9}{249} \times 100

On simplification, we get

\frac{27.9}{249} \times 100

Discount Percent = 11.20%

Result:

Hence from the given data, we got the discount percent is 11.20%
