Answer:
1) Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) I disagree
3) 7.88
4) 2.32
5) Ahmed = 60 kg
Jasim = 20 kg
Dalal = 100 kg
Step-by-step explanation:
1) diameter = 24 cm was rounded up to the nearest cm.
Now, usually, we round up 0.5 to the next whole number. This means that, the actual diameter is;
23.5 ≤ D < 24.5
Thus;
Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) If you weigh 57g,converting to kg is 0.57 kg.
Now, this does not fall in between 56.5kg and 57.5kg given.
Thus, I disagree that your weight could be anything between 56.5kg and 57.5kg .
3) 7.875 approximated to the nearest two decimal place = 7.88
4) 2.3242900000 to the nearest 2 decimal place = 2.32
5) 180 kd shared between ahmed ,jasim and Dalal in the ratio of 3:1:5.
Total part of ratio = 3 + 1 + 5 = 9
Their respective shares are;
Ahmed = 3/9 × 180 = 60 kg
Jasim = 1/9 × 180 = 20 kg
Dalal = 5/9 × 180 = 100 kg
