Amilkyway bar is 5 inches long. the bar will be split into two pieces. for each situation find the length in inches of the two pieces and write your answer as the ratio of the larger piece to the smaller piece. show your worka) one piece is 1 inch longer than the other? b) one piece is 60% of the bar asap

A)one is 3 inches and the other is 2 inches.2:5 and 3:5

B)It would be still b three and two because 3/5 of the chocolate bar is 60% and 2/5 is 40%.

Step-by-step explanation:

A) If the bar is 5 inches long and it is broken into two pieces with one that measures an inch longer then you would find that if broken in half it   would be 2.5, so if you take the other point 0.5 off of the other 2.5 and add it to the other half then it would have on piece that is an inch longer than the other piece.3+2=5

B)  5(0.6) =3

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
