Запиши ответы По формуле S = ab найди значение: 1 S, если S = a = 7 1/4 * ub = 16/29 . 2 b, если S=72 vee a = 36/49 ; b =

To find the value of S using the formula S = ab, where a = 7 1/4 and b = 16/29, we substitute the given values into the formula:

S = (7 1/4) * (16/29)

To multiply fractions, we multiply the numerators and denominators separately:

S = (29/4) * (16/29)

The numerator of b cancels out with the denominator of a:

S = 4 * 16 S = 64

Therefore, S = 64.

To find the value of b using the formula S = ab, where S = 72 and a = 36/49, we substitute the given values into the formula:

72 = (36/49) * b

To solve for b, we can multiply both sides of the equation by the reciprocal of (36/49), which is (49/36):

72 * (49/36) = (36/49) * b * (49/36)

The (36/49) terms cancel out on the right side of the equation:

b = 72 * (49/36)

To simplify the expression, we can divide 72 by 36 to get:

b = 2 * 49

b = 98

Therefore, b = 98.
