Answer:
66
Step-by-step explanation:
7(12)+3(-6)
84-18=66
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
I honestly don’t know the answer to this question but I hope you find an answer soon and good luck
<u>We are given:</u>
Afsheen can read 39 pages in 30 minutes
<u>Time taken by Afsheen to read 1287 pages:</u>
Time taken to read 1 page:
Time taken to read 1 page = time taken to read 39 pages / 39
Time taken to read 1 page = 30 minutes / 39
Time taken to read 1 page = 0.77 minutes
Time taken to read 1287 pages:
Time taken to read 1287 pages = Time taken to read 1 page * 1287
Time taken to read 1287 pages = 0.77 * 1287
Time taken to read 1287 pages = 991 minutes OR 16.52 hours <em>(Approx)</em>
