Answer:
blue
Step-by-step explanation:
If two red marbles are removed, 1 red is returned. The number of reds is reduced by 1, and the number of blues is unchanged.
If two blue marbles are removed, 1 red is returned. The number of reds is increased by 1, and the number of blues is decreased by 2.
If one of each is removed, one blue is returned. The number of reds is reduced by 1, and the number of blues is unchanged.
So, at each step, the number of blue marbles is unchanged or reduced by 2. That is, it only changes by an even number. The number of blues is initially odd, so can never reach zero.
The last marble in the bag is blue.
it is commutative i just took the test and got a 100 argh 7th grade i tell you
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
C is ur answwer
Hope this helpss
Given:
The length of the given prism = 6 m
The width of the given prism = 3 m
The height of the given prism = 12 m
To find the surface area of the prism.
Formula:
The surface area of the prism is
where, l be the length
b be the width
h be the height
Now,
Putting, l=6, b=3 and h=12 we get,
sq m
or, 
sq m
Hence,
The surface area of the prism is 252 sq m.
