Sarah’s mom took 3 hours to clean, but when Sarah helped, it took them 2 hours to clean. How many hours will it take Sarah to cl

Aleonysh [2.5K]

Answer:

It takes them 1.875 hours.

Step-by-step explanation:

Here, the job is cleaning the house.

Mom does 1 job in 3 hours.

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

Dad does 1 job in 5 hours.

In 1 hour, dad does 1/5 of the job.

Mom and dad working together do the job in x hours.

In 1 hour, mom and dad together do 1/x of the job.

1/3 + 1/5 = 1/x

5/15 + 3/15 = 1/x

8/15 = 1/x

8x = 15

x = 15/8 = 1.875

Answer: It takes them 1.875 hours.

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]

Answer:

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

Solution:

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%
