Answer:

47%

Step-by-step explanation:

the number in the tenth place is 7 and It can´t be changed because 1 isn´t 5 or it also isn´t greater than 5.

Answer:

h = 0.64 ft

Step-by-step explanation:

$s = \frac{14 + 12 + 6}{2} = \frac{32}{2} = 16 \: ft \\ \\ A = \sqrt{(s - 14)(s - 12)(s - 6)} \\ \\ A = \sqrt{(16 - 14)(16 - 12)(16 - 6)} \\ \\ A = \sqrt{(2)(4)(10)} \\ \\ A = \sqrt{80} \\ \\ A = 8.94427191\\ \\ A \approx 8.94 \: {ft}^{2}$

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft

madreJ [45]

Answer:

Fast train speed: 69 km/h

Slow train speed: 39 km/h

Step-by-step explanation:

Fast train:

-Time: 4.33

-Speed: x

-Distance: 4.33x

Slow train:

-Time: 7.66

-Speed: x - 30

-Distance: 7.66(x - 30)

7.66(x - 30) = 4.33x

7.66x - 229.8 = 4.33x

3.33x = 229.8

x = 69
