161 1-foot tiles.
EXPLANATION:
To find how many tiles we need,
We must find the area of the kitchen.
To find the area, you multiply
length x width
In this question,
the length is 14
the width is 11.5
14 x 11.5 is 161.
So 161 1-foot tiles to cover the kitchen.
Hope this helps! Have a gud day!
Answer:
I'm not completely sure but if they want exponents for 6 * 6 * 6 then it should be 
Step-by-step explanation:
25% 6 divided by 24 will give you the percentage of copper in the bar
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
The "relative frequency" is
(number of times a blue marble came out)
divided by
(total number of trials before everybody got bored and quit) .
-- The relative frequency of blue was (20/60) = (33 and 1/3) % .
(Even though 38.5% of the marbles in the jar are blue,
they didn't get picked that often.)
-- The relative frequency of green was (18/60) = 30 % .
(Even though only 26.9% of the marbles in the jar are green,
they got picked more often than that.)
-- The relative frequency of red was (22/60) = (36 and 2/3) % .
(Even though 42.3% of the marbles in the jar are red,
they didn't get picked that often.)
