erastovalidia [21]

Answer:

adults : 0  children: 600

Step-by-step explanation:

x + y = 600

6x+4y = 2400

4×(x + y = 600) = 4x+4y = 2400

(6x+4y = 2400) - (4x+4y = 2400) = x=0

so y=600

Find the length of side xz give your answers to 3 significant figures
aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = \frac{adjacent}{hypotenuse} = \frac{ZY}{XZ} = \frac{12.6}{XZ}

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = \frac{12.6}{cos29} ≈ 14. 4 ( to 3 sig. figs )
