I think it’s 3 at least from my knowledge
3/10 -c
2/10-b
9/10- h
7/10-g
1/10-a
So we know that 22% of the mass off the chocolate bars is pecans, and that 4.5kg of pecans were used. To find the mass of nutty chocolate bars made with 4.5kg of pecans we can divide the 4.5 by 22 to find 1% of the weight of nutty chocolate bars produced, then multiply it by 100 to find the full weight in kg.
So 4.5/22= 0.205 (3dp), then 0.205x100=20.5kg of nutty chocolate bars produced.
Now to convert the kgs of chocolate bars to lbs, we multiply by 2.205 (as there is approximately 2.205 lbs to 1 kg).
So 2.205x20.5kg=45.203 lbs (3dp) of nutty chocolate bars produced on Tuesday.
Answer:
The answer is 20 meters squared
base area = side^2 = 2^2 = 4 m^2
base perimeter = (2 x 4) = 8 m
lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2
surface area = (base area + lateral surface) = (4 + 16)= 20m^2
I think the answer is: r=13/16
