Answer:
A. 42½ units
Step-by-step explanation:
the volume = 5×2×4¼ = 10×4¼ = 42½
Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of

if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so

this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is

and the last one is KYXLMJ (the top "triangle")
the volume is

so now add them up
and has to equal 444

and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes

3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D
Answer:
0.5 inches per month
Step-by-step explanation:
There are nearly 0.3937 inches in 1 cm, so

There are 12 months in the year, so'
15 centimeters per year is equivalent to

The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.
A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.
The dimensions of the original photo is 6 x 6.
The answer is y = 8 from the photo
