Answer:
7.5x6.5=48.75
Step-by-step explanation:
To find decimal form, you first have to change 1/4 into a decimal. That equals 0.25. The percentage would be 6.25%. Now to find the decimal equivalent, move the decimal two places to the left. To fill in the one missing place, add a zero before the 6. Therefore, 6 1/4% is equal to 0.0625 in decimal form.
Answer:
9 pieces of candy.
Step-by-step explanation:
The information about how many boys there are is irrelevant, so we can just ignore that.
The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.
So, to solve, we just do 396 / 44 = 9.
Therefore, each student will get 9 pieces of candy.
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
