To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.
55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.
So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.
Would it be 3.4, 4.3, 5.2, 6.1, 7
Answer:
24 ft
Step-by-step explanation:
Hypotenuse = √9²+16²=√81+256=√400=20ft
the upper side of the stuff = 4 ft
total = 20+4=24
I think is is:
7/20=35/100=0.35=35%
Hope I'm not wrong!
Hope this helps! :D
Answer:
see explanation
Step-by-step explanation:
(1)
given
4x² = 81 ( divide both sides by 4 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
---------------------------------------------------------------------
(2)
subtract 7 from both sides
(4x - 3)² = 32 ( take the square root of both sides )
4x - 3 = ± 
= ± 4
Add 3 to both sides
4x = 3 ± 4 ( divide both sides by 4 )
x = 
±
