change the mg in the question to g which is
if 10cc contains 5g therefore
0.35g would give?
13 is simplest form
lol I have the same homework ;)
Answer:
15 centimeters.
Step-by-step explanation:
We must calculate the volume of each cylinder and add it, like this:
v = pi * (r ^ 2) * l
replacing:
v1 = 3.14 * (5 ^ 2) * 7
v1 = 549.5
v2 = 3.14 * (10 ^ 2) * 5
v2 = 1570
The sum would be:
549.5 + 1570 = 2119.5
That would be the volume of the cylindrical disk, this case would be the same formula only that it would not be length but thickness, like this:
v = pi * (r ^ 2) * t
we want to know r, therefore:
r ^ 2 = v / pi * t
replacing:
r ^ 2 = 2119.5 / (3.14 * 3)
r ^ 2 = 225
r = 15
which means that the radius would be 15 centimeters.
Hello!
Explanation:
Distributive property: a(b+c)=ab+ac
Multiply by the numbers.
Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.
First, apply used their FOIL.
Foil: (a+b)(c+d)=ac+ad+bc+bd
2x*7x+2x(-6z)+5z*7x+5z(-6z)
Then you can also apply by the minus/plus sign.
2*7xx-2*6xz+5*7xz-5*6zz
And finally simplify by equation.
2*7xx-2*6xz+5*7xz-5*6zz
<em><u>Answer: =14x²+23xz-30z²</u></em>
Hope this helps!
