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
Answer:5c+4
Step-by-step explanation:
The answer is (a) 8m
This is because, if the length is 3 times as long as the width, you would multiply the numbers by 3 to give you a length.
8×3=24 16×3=48
We can stop at this point as we know the perimeter is 64 and to work out the perimeter you add up all the sides. 48+48+16+16 is larger than 64 so the only smaller number is 8. We can check this is correct by adding up the numbers.
8+8+24+24=64
We now know that the width of the field is 8m.

Answer:
5, 8, and 9
Step-by-step explanation:
If the function is to be factorable, then k must be values which have factors that add to 6.
6 can be added as 1+5, 2+4, and 3+3. These pairs of factors multiply to 5, 8, and 9.
