4 3/4 =19/4=57/12
57/12 is larger than 38/12
20 medium and large pumpkins
m ... number of medium pumpkins
l ... number of large pumpkins
20 = m + l
20 = m + (m + 6)
20 = 2 * m + 6
2 * m = 20 - 6
2 * m = 14
m = 7 medium pumpkins
l = 20 - 7 = 13 large pumpkins
Result: Julio bought 13 large pumpkins.
You are multiplying the numbers by 8 so it would most likely be patrick
Arc length = radius * central angle (radians)
central angle (radians)= arc length / radius
central angle (radians)= 60 / 15
central angle (radians)= 4 radians
sector area =(central angle / 2) * radius^2
sector area = (4 / 2) * 225
sector area = 450
