The rise of the segmental arc is 10 cm, its span
is 100 cm and IZXI = IZYI = 120 cm.
Calculate, taking a to be 22 where necessary,
a) the radius of the circle
b) the area of the segmental cap, correct to
2 significant figures
c) the total area of the design, correct to
3 significant figures. (WAEC/SSCE]

2x+3y=12 x-y=6 solve the following system equations

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
