Answer: im guessing you need the amount of compound b
Step-by-step explanation:
1 think out problem
compound A =222m compound B=3 milliliters of compound A used for every 2 milliliters of compound B
write compound B as an equation which is:
a=3+2b
compound a equation is: a=222
to continue you have to make compound B equation equal b
a=3+2b
-2b -2b
a-2b=3
-a -a
-2b/-2=3/-2-a/-2
b= -3/2+a/2
i am working on the substitution method: so now you substitute variables
problems are: b=-3/2+a/2 and a=222
substute a for a: b=-3/2+222/2
b=109.5
a=222
<u>compound A=222</u>
<u>compound B=109.5</u>
<u>add both for final answer or whatever: 109.5+222= 331.5</u>
<em>sorry for the long complicated answer hope you understand. i tried my best it should be right. sorry if my answer is wrong. </em>
We know that
volume of a right circular cylinder=pi*r²*h
where
r ----> is the radius
h---> is the height
in this problem
r=6 cm
h=?
Volume=550 cm³
so
V=pi*r²*h------> h=V/[pi*r²]----> h=550/[3.14*6²]----> h=4.87 cm
<span>Round to the nearest tenth
</span>h=4.9 cm
the answer is
4.9 cm
