Cardi B is building a rectangular recording studio. Her architect created a blueprint for her using a SCALE OF ½ CM TO 3 FEET. The dimensions of the blueprint are :
9 cm long by 4.5 cm wide. WHAT ARE THE ACTUAL DIMENSIONS OF HER RECORDING STUDIO?

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: idk
