You are in charge of a crew that inspects cars. Each car takes approximately 1/2 hour for 1 person to inspect. The normal crew h

jonny [76]

Answer:

Each inspectors NEEDS to work 20 hours in order to review 320 cars.

Step-by-step explanation:

The amount of time taken to inspect 1 car = 1/2 hr = 0.5 hr

The total people in crew are supposed to be 10

But 2 people are MISSING.

So, the total number of present people in crew = 10 - 2= 8

The total number of cars to be inspected = 320 cars.

Since each car takes 0.5 hour to be reviewed.

So, the time required to review 320 cars = 320 x 05 = 160 hours.

So, the total hours needed to inspect all 320 cars = 160 hours

Now,as there are total 8 crew members.

$\implies \textrm{The number of hours each inspector needs to work} = \frac{\textrm{Total working hours needed}}{\textrm{Toal number of inspectors}} \\= \frac{160}{8} = 20$

Hence , each inspectors NEEDS to work 20 hours in order to review 320 cars.

Lucy has a 40-inch T.V. This means the diagonal distance from one corner of the T.V. to the other is 40 inches.

masha68 [24]

Using Pathogorean Theorem.....

40 = the square root of 24^2 + 32^2
40 = the square root of 576 + 1024
40 = the square root of 1600
40 = 40

Phil had 93 dollars, and his sister owed 10 dollars to her friend. How much should Phil give to his sister for each of them to h

Olegator [25]

Answer:

Phil should have $41.5 and Phil should give $51.5 to her sister.

Step-by-step explanation:

Given that,

amount of money Phil have = $93

amount of money Phil's sister owed to her friend = 10

$10 of the $93 is going to his sister's friend; that leaves $83 for Phil and his sister.

If they are to finish with the same amount, then each should have half of the Phil's money after she paid $10

So,

83/2

= 41.5 each but since Phil's sister have to give 10 rupees in debt so

41.5+10

= 51.5

So Phil should have $41.5 and Phil should give $51.5 to her sister.
