The italian size of a suit jacket is n centimeters, where n is the linear distance between the armpits. the american size of a suit jacket is 2.5p centimeters, where 2.5p is twice the linear distance between the armpits. if, for a particular jacket, n = p + 10, which of the following is closest to the value of n? (one inch is approximately 2.54 centimeters.)
a) 36b) 47c) 58d) 65e) 72

  B)  47

Step-by-step explanation:

If we assume the 2.5P is more accurately 2.54P, then we have two relations between N and P:

Solving the second for P gives ...

   P = N -10

and substituting that into the first gives ...

  2.54(N -10) = 2N

  0.54N -25.4 = 0 . . . . . . subtract 2N

  N -47.037... = 0 . . . . . . .divide by 0.54

  N ≈ 47 . . . . . . . . . . . . . . add 47.037... and round

The closest value of N is 47.

Comment on the problem

If you take the problem at face value, you compute N=50. The closest offered answer is still 47. In this scenario, the relationship between inches and centimeters is irrelevant, as there are no inches anywhere in the problem.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
