Question

calcula la media proporcional en cada caso

Answer 1

Explicación paso a paso:

2 ítem.

36/X = X/4

144 = X² /×✔

12 = X

–35/10 / b = b / –14

–7/2 / b = b/–14

–7/2×–14 = b²

98/2 = b²

49 = b² /×✔

7 = X

8/y = y/72

576 = y² /×✔

24 = y

22/10 / m = m / 845/11

11/2 / m = m / 845/11

11/2 × 845/11 = m²

845/2 = m² /×✔

✔845/2 = m

13✔5 / ✔2 = m

d/5= 80/d

d²= 400 /×✔

d = 20

m/ ½ = 45/10 / m

m² = 45/10 × ½

m² = 9/2 ×1/2

m²= 9/4 /×✔

m= 3/2
