8. Perimeter:5.9*2 or you can write 5.9+5.9 equals to 11.8 then add the 3.4
9.perimeter : 8.2+4.2+9.17
Area:(8.2*4.1)/2
Answer: the answer is D
Step-by-step explanation:
The greatest comment factor of 28 and 64 is 4.
The factors of 28 are 28, 14, 7, 4, 2, 1.
The factors of 64 are 64, 32, 16, 8, 4, 2, 1.
The common factors of 28 and 64 are 4, 2.
the greatest one of the two factors is 4.
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:
Correct, as 4 is the only number repeating twice
