42 received an A
so 40-42 = 38 did not
the fraction would be 38/80, divide both numbers by 2
38/80 reduces to 19/40 did not receive an A
Answer:
348
Step-by-step explanation:
Length-l
Width-w
Height-h
A=2(wl+hl+hw)=2·(8·9+6·9+6·8)=348
The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
(30.26/35.6)*100= 85%
check: .85 * 35.6 = 30.26
The best answer would be C.
Hope this helps:)
