A forest fire has been burning for several days. The burned area, in acres, is given by the equation y = (4,800) = 24, where d is the number of days
since the area of the fire was first measured.
Complete the following table:
d, days since first measurement
y, acres burned since fire started

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
