To find the car's total price, add the tax paid to the car's original price.

$32800 + $1968 = $34768

The total cost is $34,768

100% + 6% = 106%

If 6 pipes fill a tank in 120 minutes, then 5 pipes can fill it in how many minutes

Marianna [84]

Answer:

It'll take 144 minutes for 5 pipes.

Step-by-step explanation:

${ \sf{6 \: pipes = 120 \: mins}} \\ { \sf{5 \: pipes = ( \frac{6}{5} \times 120) \: mins}} \\ \\ = { \sf{144 \: mins}}$

but practically, it seems to be abnormal. if 6 pipes take 120 mins, 5 pipes must takes a time greater than 120 mins cause amount of water flowing to the tank is decreasing.

But there is a possibility that pressure of water was increased for the case of five pipes, that's why it takes a time less than 120 mins. (t < 120)

Mark and clean his father's office in 30 minutes his younger sister Lynn can clean the office in 40 minutes how long will it tak

egoroff_w [7]

we are given

Mark clean his father's office in 30 minutes

so, the amount of work done by Mark in 1 minute is $\frac{1}{30}$

younger sister Lynn can clean the office in 40 minutes

so, the amount of work done by younger sister Lynn in 1 minute is $\frac{1}{40}$

total work done by them in 1 minute is $\frac{1}{30}+\frac{1}{40}$

now, we can simplify it

$=\frac{4*1}{4*30}+\frac{3*1}{3*40}$

$=\frac{4+3}{120}$

$=\frac{7}{120}$

total time taken to complete same work is $\frac{120}{7} min$ ........Answer
