Step-by-step explanation:
In the glass tank:
W = represents the volume of water Andrei uses (in liters)
n =Number of marbles
Given that:

Therefore:

Volume of the tank =32 Liters
Answer:
Jude is not correct
Step-by-step explanation:
The volume of a square pyramid is given as:

where a = base edge and h = height
Hence, the volume of the square pyramid with base edge of 7 in and height of 7 in is:

V =
≅ 
The volume of a cylinder is given as:

where r = radius and h = height
Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V =
≅ 
Since their volumes are not equal, Jude is not correct.
We use the formula
L = rθ
where s is the arc length or the length of the wire
r is the distance from the center to the end of the rod
θ is the angle made by the rod with the wall
Substituting the values and converting the angle to radian measure
L = 4 (40°) (π/180°)
L = 2.79 feet<span />
Answer:
Given that,
My cupcake recipe makes $12$ cupcakes and requires $1\frac12$ sticks of butter. I can only buy whole sticks of butter.
Therefore, 1 whole sticks of butter is enough to make $100$ cupcakes.
