Savatey [412]

Answer:

The weight of large box is 13.25 kilograms and the weight of small box is 6.25 kilograms.

Step-by-step explanation:

Given:

A fruit company delivers its fruit in two types of boxes large and small a delivery of three large boxes and five small boxes that has a total weight of 71 kilograms and a delivery of six large boxes and two small boxes has a total weight of 92 kilograms.

Now, to find the weight of each type of box.

Let the weight of large box be $x$ .

And let the weight of small box be $y.$

A delivery of three large boxes and five small boxes has a total weight of 71 kilograms:

$3x+5y=71\ \ \ .....(1)$

And, the delivery of six large boxes and two small boxes has a total weight of 92 kilograms:

$6x+2y=92\\\\Subtracting\ both\ sides\ by\ 6x:\\\\2y=92-6x\\\\Dividing\ both\ sides \ by\ 2\ we\ get:\\\\y=46-3x\ \ \ \ ......(2)$

Now, substituting the value of $y$ from equation (2) in equation (1):

$3x+5y=71\\\\3x+5(46-3x)=71\\\\$

$3x+230-15x=71\\\\230-12x=71\\\\$

Subtracting 230 on both sides we get:

$-12x=-159$

Dividing both sides by -12 we get:

$x=13.25.$

The weight of large box = 13.25 kilograms.

Now, substituting the value of $x$ in equation (1) we get:

$3x+5y=71\\\\3(13.25)+5y=71\\\\39.75+5y=71\\\\Subtracting\ both\ sides by\ 39.75\ we\ get:\\\\5y=31.25\\\\Dividing\ both\ sides\ by\ 5\ we\ get:\\\\y=6.25.$

The weight of small box = 6.25 kilograms.

Therefore, the weight of large box is 13.25 kilograms and the weight of small box is 6.25 kilograms.

Decimal a = 2.5m; decimal b = 4.0m; decimal c = 12.7m; int i = 4; int j = 8; int k = 17; What is the value of x after the follow

ra1l [238]

Answer:

Option b(0.5) is the correct answer for the above question.

Step-by-step explanation:

The above code is written in the C# language. The first three statements are used to declare the three decimal variable and initialize them by some value. But this has no use in the above code.
Then there are the other three statemen which is used to declare the three variable of type integer which names are i,j and k and initialize them to a value 4,8 and 17.
Then the expression "decimal x = (decimal)i / (decimal)j;", intialize the value 0.5 to the x variable.
It is because the i and j value will be typecast in the decimal value and then i is divided by j. It means (4.0) is divided by (8.0) which gives the result 0.5.
Hence option b is the correct answer while the other is not because the other option is not the value of the x variable.
