Answer:
volume= 1040
surface area=696
Step-by-step explanation:
1/2x 13x10x16
=1040#
(1/2x12x10)2
=120
(16x13)2
=416
16x10
=160
120+426+160
=696#
Answer:
Step-by-step explanation:
Given

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
Take any fraction, proper or improper, and then multiply both the numerator and denominator by any number you want.
An example is one-half (1/2)
1/2 = 2/4 = 4/8 = 12/24 = 25/50 = 50/100 = 1000/2000 = 1024/2048
All of those are the same 1:2 ratio, just expressed in different forms.
