Jackie is reading a 252 page novel for her summer reading project. On Monday she reads 4/8 of the novel. On Tuesday she reads 28
natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

  • Number of pages she read on Monday = \frac{4}{8} x 252 = 126 pages
  • Number of pages she read on Tuesday = 28 pages
  • Number of pages she read on Wednesday = \frac{1}{4} x 252 = 63 pages

The total number of pages she has read so far = 126 + 28 + 63 = 217 pages

How to factor 25x^2 - 81= 0
dalvyx [7]
Your question is a difference of squares. both terms that need to be factored are squared. to solve take the square root of each put into two terms one of addition and one of subtraction.

anwser= (5x-9)(5x+9)

the reason this works is because when you foil you get
25x²-45x+45x-81 
the middle terms cancel revealing
25x²-81

A chef draws cookies randomly from a box containing 6 cookies of the same shape and size. There is 1 chocolate cookie, 3 almond
vovangra [49]

Answer:

1/5

Step-by-step explanation:

The probability of drawing an almond cookie the first time is 3/6=1/2, since there are a total of 6 cookies and 3 of them are almond. However, the second time the chance is 2/5, since there are 5 cookies left and only two of them are almond. The equation to model this is therefore:

P=\dfrac{1}{2}\cdot \dfrac{2}{5}=\dfrac{1}{5}

Hope this helps!
