Let the angles be x, 2x, 3x, and 4x. The sum of angles in a quadrilateral is 360 degrees. Therefore, x + 2x + 3x + 4x = 360, which gives 10x = 360, so x = 36 degrees. The largest angle = 4x = 144 degrees.

Let the angles be 2x, 3x, and 4x. Then, 2x + 3x + 4x = 180 degrees. Therefore, 9x = 180, x = 20. The largest angle is 4x = 80 degrees.

Let the angles be 2x, 3x, and 4x. Then, 2x + 3x + 4x = 180 degrees. Thus, 9x = 180 degrees, x = 20 degrees. The largest angle = 4x = 80 degrees.

Area = πr² = 50π. Thus, r² = 50, r = √50 = 5√2 cm. Diameter = 2r = 10√2 cm ≈ 20 cm.

Area = Length × Width. Therefore, Width = Area / Length = 48 / 8 = 6 units.

Area = 1/2 * base * height. Thus, 30 = 1/2 * 10 * height. Solving gives height = 6 cm.

Area = 1/2 * base * height, so 48 = 1/2 * 12 * height, height = 48/(6) = 8 cm.

The area of a triangle is given by (1/2) * base * height. Thus, 60 = (1/2) * 10 * height. Solving for height gives height = 12 units.

Area = 1/2 * base * height. Therefore, 60 = 1/2 * 12 * height, which gives height = 10 units.

Area = 1/2 * base * height. Therefore, 60 = 1/2 * 10 * height, which gives height = 12 units.

Area = 1/2 * base * height. Therefore, 60 = 1/2 * 10 * height, which gives height = 12 units.

Area = 1/2 * base * height. Therefore, 60 = 1/2 * 12 * height, which gives height = 10 units.

Area = 1/2 * base * height. Therefore, 60 = 1/2 * 12 * height, which gives height = 10 units.

The atmospheric pressure at 5000 meters is approximately 700 hPa.

The atmospheric pressure of 1013 hPa is equivalent to 760 mmHg.

Total age = Average age * Number of members = 50 * 545 = 27250, approximately 29000.

Total days = 3 × 14 = 42 days.

Sum = Average * Number of items = 50 * 10 = 500.

Total of 6 numbers = 6 * 30 = 180.\n\nNew total = 180 + 10 = 190.\n\nNew average = 190 / 6 = 31.67.

Mean = (7 + 9 + 11 + 13) / 4 = 10.

Total sum = Average * Number of items = 12 * 6 = 72.

Average = Total Sum / Number of Items. Therefore, Total Sum = Average × Number of Items = 20 × 5 = 100.

The total of the five numbers is calculated as average * number of items = 60 * 5 = 300.

Discharge is directly proportional to velocity. If velocity doubles, discharge also doubles.

Area = (1/2) * base * height = (1/2) * 10 * 5 = 25 cm².

Temperature in Kelvin (K) = °C + 273 = 100 + 273 = 373 K.

Radius = distance from center to point = √[(7-3)² + (1-4)²] = √[16 + 9] = √25 = 5 units.

The chance of not contracting the disease = 1 - (1/500) = 499/500 = 0.998 = 99.8%.

Circumference = 2πr. Setting 31.4 = 2 × 3.14 × r gives r = 5 units.

The circumference C = 2πr. Setting 31.4 = 2 * 3.14 * r gives r = 5.
