One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together? If x represents how many minutes to do the job together, then how much of the job does the slowest person do?

1. x/15
2. x/10
3. 15/x

Answers

Together they can complete the whole job in 6 minutes.

The amount of work done by the slowest person is $(x)/(15)$ .

What is time, work done, and rate formula?

The time, work and rate formula is given by

Work done = time × rate of wok

According to the given question.

One person can do a certain job is 10 minutes.

⇒ The work done in 1 minute by the first person or the rate of work done by the first person = $(1)/(10)$

Another person can do the same job in 15 minutes.

⇒ The work done in 15 minutes by another person or the rate of work done by the second person = $(1)/(15)$

So,

The amount of work done by both of them in one minute

= $(1)/(10) + (1)/(15) =(1)/(6)$

⇒ Together they can complete the $(1)/(6)$ th part of the work in one minute.

Therefore, together they can complete the whole job in 6 minutes.

As, we know that

Work done = Total time taken × Rate of work done

Since, the second person is taking 15 minutes to complete the jo.

So, he is the slowest person.

Total time total time taken by the two persons to complete the job together is x (given).

Also, the rate of work done by the slowest person = $(1)/(15)$

Therefore,

The amount of work done by the slowest person = $x ((1)/(15) )$

Hence, the amount of work done by the slowest person is $(x)/(15)$ .

I believe the answer you may be looking for is 2. x/10.

John paid $32.16 for groceries this included the 7% sales tax what was the cost of groceries before the sales tax

Answers

The answer is $30.06.

John added 7% of tax to the price before tax which is 100%. So, the price John paid is 107%. If $32.16 is 107%, how many $ is 100% (the price before tax):
$32.16 : 107% = x : 100%

After crossing the products:
x · 107% = $32.16 · 100%
⇒ x = $32.16 · 100% ÷ 107% = $30.06

Therefore, the cost of groceries before the sales tax is $30.06.

Answer The answer would be $30.06

Complete the pairs of corresponding parts if △ RST ≅ △ TXY. ∠ R =
∠ XYT
∠ XTY
∠ TXY

Answers

Solution:

Given: △ RST ≅ △ TXY

We are given ΔRST and ΔTXY are congruent to each other.

If two triangles are congruent to each other then their corresponding parts are equal.

Please see the attachment of two triangles.

∠R is corresponding to ∠T

∵ ∠R=∠T By CPCT

∠XYT is corresponding to ∠STR

∵ ∠XYT=∠STR By CPCT

∠XTY is corresponding to ∠SRT.

∵ ∠XTY=∠SRT By CPCT

∠TXY is corresponding to ∠RST

∵ ∠TXY=∠RST By CPCT

CPCT: Congruent part of congruence triangle.

So, two triangles are similar. Ordering of letters matters when you are writing this down. So, RST~TXY, then ∠R = ∠T, or ∠TRS = ∠YTX = ∠XTY
