Answer:

The correct answer is option B.

Step-by-step explanation:

Given quadratic equation : y^2-12y+32

Using middle term splitting theorem:

=y^2-12y+32

=y^2-8y-4y+32

=(y-8)(y-4)

y = 8, 4

kolezko [41]

Answer: 6/625 gallons of water wa splashed out of the pool

Step-by-step explanation:

Total number of gallons of water in the pool was 10 1/2. Converting to improper fraction, it becomes

21/2 gallons.

Jake and his friend splashed g gallons of water out of the pool. There are 7 7/8 gallons still left in the pool. Converting 7 7/8 to improper fraction, it becomes

63/8 gallons

This means that

g + 63/8 = 21/2

g = 21/2 - 63/8 = (84 - 63)/8

g = 21/8 = 2.625 gallons

16. Considering the "kindergarten-path effect," if your 4.5-year-old sister was asked to Put the bunny on the blanket on the she
sweet-ann [11.9K]

Answer:

if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

Step-by-step explanation:

If your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, the chance that she might follow the instructions she receives is less 50 percent. In other words:

                                      Chance < 50%

The reason is that children at this age may have challenging time figuring out the subject when you may instruct certain things to do, as the sentences could be tricky for the children to decode the meaning.  

So,  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.
