56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
Volume of a cone = (1/3) * Area of Base * height
144 * 3 / 9 = Area of Base
Area of the Base = 48
Answer:
A
Step-by-step explanation:
a = 10 X 5 = 50, 25 X 2 = 50 = 100
B = 15x5 = 75, 20 x 2 = 40, = 105
C = 20 x 5 = 100, already at 100 (so immediately wrong)
D: 25 x 5 = 125, already larger than 100 (so immediately wrong)
Therefore A is the only correct option, hop i helped you!

Answer:
a.) First check on the height of the bar that ranges between 20 and 24 which is 6. The 6 is the number of students who bought 20 books or more, so get the percentage of those students who bought 20 or more books; divide 6 which is the number of students who bought 20 books or more with the total number of students which is 40 then multiply with 100.
% of students who bought 20 or more books = 6/40 ×100
=15
Step-by-step explanation:
b.) Find the area of a trapezium
= 1/2 × {a+b} × h
= 1/2 × {9 + 13} ×12
= 132
= 1/2 × {13 + 6} × 12
= 108
Mean no. of books bought = 132 + 108
= 240
