Step-by-step explanation:
1. 'x' is the total no. of students and 'y' is no. of 6th graders.
1/3 of the total students are 6th graders.
So the equation will be
1/3 × x = y
x/3 = y
2. If x = 90
y = 90/3
y = 30
3. If x = 27,
y = 27/3
y = 9
4. If y = 42
x/3 = 42
x = 42 x 3
x = 126
The answer is A: Whose, the reason it is whose is because whose shows possession while Who's is Who is and Who is what you use when you ask who a person is! Hope this helps!!

Answer:
The answer is option b.
<h2>144π</h2>
Step-by-step explanation:
Surface area of a sphere is 4πr²
where r is the radius
diameter = radius / 2
<h3>
<u>For Big </u><u>sph</u><u>ere</u></h3>
radius = 15 / 2 = 7.5in
Surface area = 4π(7.5)²
= 225π
<h3><u>Small </u><u>sph</u><u>ere</u></h3>
radius = 9/2 = 4.5in
Surface area = 4π(4.5)²
= 81π
Difference of the surface areas is
Surface area of big sphere - surface area of small sphere
Which is
225π - 81π
<h3>= 144π</h3>
Hope this helps you.
