Myriah wants to use dimensional analysis to find out how many centimeters (cm) are in 1.4 meters (m). which of these equalities will be useful for this calculation?

Option (4) is the answer.

Step-by-step explanation:

The given question is without options ; here is the complete question.

Myriah wants to use dimensional analysis to find out how many centimeters (cm) are in 1.4 meters (m). Which of these equalities will be useful for this calculation?

2.54 cm = 1 in.

1 m = 39.37 in.

1 cm = 10 mm

100 cm = 1 m

During the dimensional analysis Myriah wants to convert the dimension from meter to centimeter.

Option (1), In this option given equality is to convert centimeter to inch. which is not required.

Option (2), In this option equality is to convert meter to inch which is not required.

Option (3) the equality given will convert cm to mm, which is not required.

Option (4) equality given in this option will convert meter to centimeter which is the required equality.

Therefore, Option (4) will be the answer.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
