Answer: Option B

Explanation:

To find the length of the diagonal path of a rectangular field, we can use the Pythagorean theorem. Let's denote the length of the rectangular field as "L" and the width as "W." Given: Length of the rectangular field (L) = 30 meters Perimeter of the fence = 140 meters The perimeter of a rectangle is given by the formula: Perimeter = 2(L + W). We're given that the perimeter is 140 meters: 140 = 2(L + W) Now, we can solve for W: 2(L + W) = 140 L + W = 140/2 L + W = 70 We know that L is 30 meters, so we can find W: 30 + W = 70 Subtract 30 from both sides: W = 70 - 30 W = 40 meters Now that we have the length (L = 30 meters) and the width (W = 40 meters), we can use the Pythagorean theorem to find the length of the diagonal path (D): D² = L² + W² D² = (30²) + (40²) D² = 900 + 1600 D² = 2500 Now, take the square root of both sides to find D: D = √2500 D = 50 meters So, the length of the diagonal path of the rectangular field is 50 meters.

Answer: Option D

Explanation:

1st condition, G = 2H - 10
2nd condition, G + H = 425
H = 425 - G
Now, G = 2(425 - G) - 10
G = 850 - 2G - 10
G + 2G = 840
3G = 840
G = 280

Answer: Option C

Explanation:

To find the largest 3-digit number using the digits x, y, and z (where x + y + z = 12), you want to maximize the leftmost digit to make the number as large as possible.

The largest possible leftmost digit is 9, as it's the largest single-digit number. To form the largest 3-digit number, you should place 9 as the leftmost digit. Now, you need to arrange the remaining digits (x and y) in the rightmost positions to maximize the number further.

To maximize the number, you should place the next largest digit (8, if available) in the hundreds place and the remaining digit in the tens place. If 8 is not available, use the next largest available digit.

So, if we place 9 in the hundreds place, and if x and y are the remaining digits, the largest number will be 9xy.

Now, we need to find the combination of x and y that adds up to 12. The only combination that satisfies this is x = 3 and y = 0.

So, the largest 3-digit number using the digits x, y, and z (where x + y + z = 12) is 930.

Therefore, the correct answer is 930.
