(a)

Expert Solution

Explanation of Solution

For the length of the baseball bat following values are given:

100 mm, 100 cm and 100 m.

A normal baseball bat is of 42 inches. Converting this into cm as follows:

(2.54cm1inch)(42inch)=106.68cm

Converting 100 mm and 100 m to cm as follows:

Thus, 100 mm in cm will be:

100mm(1cm10mm)=10cm

Now converting 100 m to cm:

100cm1m(100m)=10000cm

Here, 10 cm and 10000 cm are not correct values for length of a baseball bat thus, the value which is closest to the correct value for a length of baseball bat is 100 cm.

There are three figures given for the weight of a man:

75 mg, 75 g and 75 kg.

The average weight of a human body is 62 kg. This value is closer to 75 kg. The other figures are 75 mg and 75 g, the values in kg will be:

75mg(10−6kg1mg)=7.5×10−5kg

A normal baseball bat is of 42 inches. Converting this into cm as follows:

(2.54cm1inch)(42inch)=106.68cm

Converting 100 mm and 100 m to cm as follows:

Thus, 100 mm in cm will be:

100mm(1cm10mm)=10cm

Now converting 100 m to cm:

100cm1m(100m)=10000cm

Here, 10 cm and 10000 cm are not correct values for length of a baseball bat thus, the value which is closest to the correct value for a length of baseball bat is 100 cm.

For the volume of a glass following values are given:

23 cc, 230 mL and 23 L.

A normal glass can hold a volume of 240 mL.

The volume 23centimeter cubes is equal to 23 mL and 23 L is equal to 23000 mL which is not possible.

There are three figures given for the weight of a man:

75 mg, 75 g and 75 kg.

The average weight of a human body is 62 kg. This value is closer to 75 kg. The other figures are 75 mg and 75 g, the values in kg will be:

75mg(10−6kg1mg)=7.5×10−5kg

And,

75g(10−3kg1g)=0.75kg

Both the values are not possible for a weight of man thus, correct answer is 75 kg.
