Answer:

He planted 44 fields do corn, and 22 each for wheat and grass.

Step-by-step explanation:

There are three subjects. If we have something that was 2x as much as wheat, and then something half as much as that, we know that the wheat and grass are equal. Then, you just need to think about how a 50 25 25 split would work out of 88.

the cost of 5 oranges and 3 apples is 43 rupees and the cost of 2 oranges and 4 apples is 34 rupees. find the cost of an orange

liraira [26]

Answer: Orange = 5 rupee

Apple = 6 rupees

Step-by-step explanation:

Let the cost of an orange be x

Let the cost of an apple be y

We can form an equation from the question given which will be:

5x + 3y = 43 ......... i

2x + 4y = 34 ......... ii

Multiply equation i by 2

Multiply equation ii by 5

10x + 6y = 86 ........ iii

10x + 20y = 170 ..... iv

Subtract iii from iv

14y = 84

y = 84/14

y = 6

An apple cost 6 rupees

Since from equation ii

2x + 4y = 34

2x + 4(6) = 34

2x + 24 = 34

2x = 34 - 24

2x = 10

x = 10/2

x = 5

The size of a television screen is measured by the length of thee diagonal of the screen. What size is a television screen that

Murljashka [212]

Answer:

approximately 6.708 feet

Step-by-step explanation:

We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:

$diagonal = \sqrt{(3\,ft)^2+(6\,ft)^2} \\diagonal = \sqrt{9\,ft^2+36\,ft^2} \\diagonal = \sqrt{45} \,ft\\diagonal = 3\,\sqrt{5} \,ft$
