Answer:
A is correct
Step-by-step explanation:
A has no solution because since the slopes are the same, setting both equations equal to each other will cancel out the slopes and result in 8=16, meaning no solution will make both sides equal to each other.
B does have a solution because of different slopes
C does have a solution because of different slopes
D does have a solution because of different slopes
Should be B the total numbers of boxes filled with reams

The surface area of the table tennis ball will be around 1256.64 mm².
<h3>What is the sphere?</h3>
A sphere is a 3D geometrical object which has a radius and becomes a point that revolves around a fixed point called the center.
A sphere has surface area and volume based upon the radius of the sphere.
For example, if you have a sphere of radius r then its surface area will be 4πr² and volume will be (4/3)πr³.
The table tennis ball is the form of a sphere.
Given that,
The diameter of a table tennis ball is 20
Radius(r) = 20/2 = 10 mm
Surface area of an sphere = 4πr²
So,
Area = 4π(10)² = 1256.64 mm².
Hence "The surface area of the table tennis ball will be around 1256.64 mm²".

Answer:
E
Step-by-step explanation:
dy/dx - sqrt(x/y) = 0
dy/dx = sqrt(x) ÷ sqrt(y)
y^½ .dy = x^½ .dx
Add 1 to the power and divide by the new power
(⅔)y^(3/2) = (⅔)x^(3/2) + c
x = 1, y = 0
0 = ⅔ + c
c = ⅔
(⅔)y^(3/2) = (⅔)x^(3/2) + ⅔
y^(3/2) = x^(3/2) + 1
At y = 73
73^(3/2) = x^(3/2) + 1
622.7122734 = x^(3/2)
x = 622.7122734^⅔
x = 72.9219527
Approximately 73
