Remark
You need a split statement like C or D. A and B would have to be considered if the ages were between 12 and 60. However the discounts apply the other way. Up to 12 and over 60. You need two inequalities to describe this.
<em><u>Under 12</u></em>
x ≤ 12
The pointy end of the arrow points toward the x. x must be less than or at most equal to 12. The pointy end of the inequality must be directed towards the smaller number.
<em><u>Over 60</u></em>
x ≥ 60
This time the pointy end is directed towards the 60. x must be at least 60 and then upwards.
So C is the correct answer.
Step-by-step explanation:
Height of the cylinder A(h1)=5cm
CSA of cylinder A(CSA1)=18cm^2
Height of the cylinder B (h2)=10cm
CSA of cylinder B (CSA)=?
Since cylinder A and B are similar,
h1=xh2
or,5cm=x*10cm
or,x=1/2
Similarly,
CSA1=xCSA2
or,18cm^2=1/2*CSA2
or,CSA2=36cm^2
We khow that,
Volume of cylinder B (V2)= CSA2 * h2
=36cm^2*10cm
=36cm^3

Her goal : 1350
What she has now: 174
she earns 84$ a month
answer is 14 months because 84* 14 is 1176 and if u add 174 $ to that it will give u 1350.
