Volume (V) of a cylinder = B x h ; where B is the area of the base and h is heighth
65 π = B x 5
13 π = B <em>divided both sides by 5</em>
Answer: 13π cm²
Answer:
A) 21.0 g of N2
Explanation:
From the periodic table:
atomic mass of nitrogen = 14 grams
This means that:
molar mass of N2 = 2(14) = 28 grams/mole
Now, from the given balanced equation, 2 moles of NaN3 produce 3 moles of N2. We can use cross multiplication to know the number of moles of N2 produced from 0.5 moles of NaN3 as follows:
2 moles NaN3 ..............> 3 moles N2
0.5 moles NaN3 ...........> ?? moles N2
number of moles of N2 = (0.5*3) / 2 = 0.75 moles
Now, we will get the mass of 0.75 moles as follows:
number of moles = mass / molar mass
mass = number of moles * molar mass
mass = 0.75 * 28
mass = 21 grams
Hope this helps :)
The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.
(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab
x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.
Thus the answer to this question is option C
Answer:
the easy way to figure this out is to just plug in answers.
start with a, (10)=3(3)+1
10=9+1
10=10
this makes this a true statement
feel free to try the other options but this is your answer
A. (3,10)
Divide 60 by however much people was there to get your answer
Hope it works
