Answer:
same time , 12 minutes
Step-by-step explanation:
'A' can eat 1÷6 pizza in 2 minutes
Therefore, 'A' can eat full pizza in 6×2 minutes=12 minutes
'B' can eat 1÷4 pizza in 3 minutes
therefore, 'B' can eat full pizza in 3×4 minutes=12 minutes
So, Both 'A' and 'B' will finish at same time.
Answer: The tank which has 3 m side.
Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:
V = length*width*height
Since they are all the same, volume will be:
V = s³
One tank has a 3 m side, so its volume is:
V = 3³
V = 27 m³
The other has half of the first one side, then s = 
and volume will be:
V = 
V = 
m³
As you can see, the volume of the second tank is 
smaller than the first one. Therefore, the tank which has 3 m side can store more water than the tank with side measuring half of the first.
<span>the discriminant D of the equation 3g² + 15g + 10 = 0
for a quadratic equation ax²+bx+c=0
the discriminant D is D= b²-4xaxc
so for </span><span> 3g² + 15g + 10 = 0 D=15²- 4x3x10=125-120=5, so D=5</span><span>

Answer: The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
Step-by-step explanation:
x is the price of the battery
x + 1.50 is the price of the torch
x + (x + 1.50) is 2.50
x + (x + 1.50) = 2.50
2x = 2.50 - 1.50
2x = 1
x = 1/2
x = 0.50
The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
