2/5 on the pie chart it says that 2/5 of the band plays a brass instrument
B. Y=4x-14
Think about where the point is on the grid and then use the slope to get to the y-intercept. So for this question your going to have to move backwards to get to the y axis. Move down 12 units and left 3 and that’ll give you the y-intercept which will match in the equation.
Answer:

Step-by-step explanation:
sinA = = , thus
sinA = =

tanA = = , thus
tanA = =
b + 8 =13
Move 8 to the other side
Sign changes from +8 to -8
b+8-8=13-8
b=5
Answer : b=5
Miles to metres: 5 = 8046.72
8046.72 / 34.7
= 23.19 m/s
