Answer: 2√10 - √30
explanation:
ok so they’re asking for the difference between the lengths of the sides of each cube. they have different SA’s (surface areas). all you gotta do is plug in the SA in the given equation to find the length of the side and THEN you subtract the answers and thats how you find the difference between the sides.
given:
s = √(SA/6)
SA1 = 240 m^2
SA2 = 180 m^2
S1 = √(240/6) = 2√10 or 6.32
S2 = √(180/6) = √30 or 5.47
s1 -s2 = 2√10 - √30
Substract 2/3 from each side.
X= 2/3, assuming that you are solving for X.
Answer:
There are 392 storybooks.
There are 49 magazines.
<h3>There are 343 more storybooks than magazines are there in the library.</h3>
Step-by-step explanation:
s = number of storybooks
m = number of magazines
The library has 441 storybooks and magazines altogether.
s + m = 441
There are 8 times as many storybooks as magazines.
s = 8m
How many more storybooks than magazines are there in the library
?
Substitute s = 8m into the original equation to find m.
s + m = 441
8m + m = 441
9m = 441
m = 441/9
m = 49
Substitute m = 49 into the original equation to find s.
s + m = 441
s + 49 = 441
s = 441 - 49
s = 392
s - m = 392 - 49 = 343
