Aleaky pool loses 2 1/4 inches of water each day. jermaine and mildred are asked to determine the change in the amount of water in the pool over 5 days. jermaine’s solution mildred’s solution 5(-2 1/4) 5(-2 1/4) 5(-2 -1/4) 5(-2 -1/4) -10 -1/4 -10 -5/4 -10 1/4 -11 1/4 which describes the reasoning used to determine whose solution is correct? a. jermaine is correct because -10 -1/4 equals -10 1/4. b. jermaine is correct because he distributed 5 correctly. c. mildred is correct because she multiplied 5 by –2 but not by -1/4. d. mildred is correct because she distributed 5 correctly.

D. Mildred is correct because she distributed 5 correctly.

Step-by-step explanation:

Since, the loss of water in one day =

⇒ The loss of water in 5 days =

⇒ The loss can be written with negative sign,

Thus, the expression that shows the changes in quantity of water in 5 days,

Since, the above steps are similar to that of Mildred's solution,

⇒ Mildred is correct.

Also, By the above explanation it is clear that jermaine incorrectly distribute 5 in his third steps.

⇒ Option D is correct.

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
