Answer:
108 square metres
Step-by-step explanation:
A=√d square - l square
here
A = area
d= diagonal
l= length
First figure out Info needed
So 142 people 6 drivers
2 vehicles of which are bus and vans
Van:capacity of 10 Bus:capacity of 51
So plug in x for buses and y for vans
x+y+6=142
Subtract 6
x+y=136
51 times 2 gives you 102 for the bus capacity so two buses
x(2)+y=136
51(2)+y=136
102+y=136
Subtract 102
Giving you 34
y=34
4 vans because
34 divided by 10 is 3.4 but there is no 3.4 van so round up to 4
You end up needing 2 buses and 4 vans
Formula for slope-intercept is y = mx+b. The y-intercept is the point where the line crosses the y-axis. From there on, use the slope to graph the line. For example, if the equation is y = 5x - 2, you would want to plot (0,-2) first on the graph. Then, continue using the slope, which is 5. Slope is rise/run. In this case, you go up five, then to the right one, since there is always an invisible one if the slope is a whole number.
Hope that helped. :)
