Answer:
C. 4
Step-by-step explanation:
All other answer choices involve the variable 'b' and/or are tied to it in some way. The sole number 4 has no connection to the variable b, therefore it is C. 4.
It will take months for the boy to grow to a height of 132cm. 132-90= 42 cm left to grow. 42÷3.5= 12months, or a year.
Calculator 1: Calculate the percentage of a number.
For example: 87% of 55 = 47.85
Calculator 2: Calculate a percentage based on 2 numbers.
For example: 47.85/55 = 87%

Answer:
resistance is 1.5 ohms (1.5 Ω)
Step-by-step explanation:
R varies directly with l
R varies inversely with 
We can set-up a proportionality statement as shown below:

Now, Given,
R = 1.50
l = 2
d = 1.5
We substitute and find k (the proportionality constant):

Now, we will use this value of k to solve the problem.
Given,
l = 8
d = 3
and
k = 1.6875
We find R:

The resistance is 1.5 ohms (1.5 Ω)
