Katarina [22]

Answer:

6 and 1/2 = 13/2

3 and 1/3 = 10/3

3 and 1/5 = 16/5

9 and 1/2? = 19/2

not sure about the 3/5, but hopefully this is what you meant

Step-by-step explanation:

multiply the whole number by the denominator, add the numerator, then put that big number over the numerator.

so... 6 and 1/2

6 × 2 (denominator) = 12

12 + 1 (numerator) = 13

13/2 (denominator)

  • <u>12º</u>

<u></u>

Explanation:

The angle Marcel's code adjust the shot can be calculated using the cosine law:

        C^2=A^2+B^2-2|A||B|cos(c)

For the triangle of the figure:

  • C = 15m
  • A = 50m
  • B = 60m
  • c = ? (the unknown angle)

Substitute and solve for c:

      (15m)^2=(50m)^2+(60m)^2-2(50m)(60m)cos(c)\\\\\\225=2500+3600-6000cos(c)\\\\6000cos(c)=2500+3600-225=5,875\\\\cos(c)=5,875/6000\approx0.97917\\\\c=arccos(0.97917)\approx12\º
