A cell doubles every 15 minutes. If there is 1 cell at noon, how many cells will there be at 3 p.m.? Show work.

Answers

Answer 1

Answer: 12:15 - 1+1 = 2
12:30 - 2 + 2 = 4
12:45 - 4 + 4 = 8
1 - 8 +8 = 16
1:15.......
.......
3 - 4096

Answer 2

Answer: okay so there is 1 cell and it starts doubling at 12:00 every 15 minutes that is 4 times every hour and there is three hours so 4 x 3 = 12 so it doubles 12 times then 12 x 2 = 24 so at 3pm that cell would have multiplied it self into 24 other cells

Choose the polygon that is a regular quadrilateral

Answers

"Regular quadrilateral" means it has four sides, and the
sides AND the inside angles are all equal.

-- The one at the upper left is a rhombus. All 4 of its sides
are the same length, and the first time I saw it, I picked it.
But then I remembered that in order to be 'regular', the
inside angles also have to be equal, and in a rhombus,
they're not.

-- The one in the lower right is a square. It has four sides,
they're all equal, and the inside angles are all the same too.
So the square is the only one that does the job for you.

600 is not prime because you can divide it by 10.
743 is prime because you can't divide it by any number.

PRQ and PRQ are obtuse angles

Simplify
2/5(a+b)+3/5(a+c)

Answers

distribute 2/5 and 3/5 into the ():
2/5(a+b)+3/5(a+c)

2/5 a+ 2/5 b+3/5 a+ 3/5 c

combine the like terms:
2/5 a+3/5 a= 5/5 a --> 1a --> a

new simplified equation:
a+2/5 b+3/5 c

Distribute

(2/5) (a) + (2/5) (b) + (3/5)(a) +(3/5)(c)

= 2/5a+2/5b+3/5a+3/5c

Combine like terms

2/5 a + 2/5 b + 3/5 a + 3/5 c

= ( 2/5 a + 3/5 a ) + ( 2/5 b) +(3/5 c)

= a + 2/5 b +3/5 c
