Well, each pizza is cut into 10 slices, that means both pizzas are 10+10 slices, or 20 slices, then they ate 14 of those 20 slices.
so they ate 14 out of 20, or 14/20, which simplifies to 7/10.
Answer: 1/27
Step-by-step explanation:
-r=5×2
-r=10
r=-10
That's your answer.
As we knw that the dr/dt = 2
And The area of the circular slick is given by formul
A = (pi)r^2.
Now lets take derivative:
<span>dA/dt=2πrdr/dt
As we knw that radius is 25
so</span><span>dA/dt=2π(25)(2)=100π
which is equal to
=314.16 per minute this is how area is increasing
now for part b
</span><span> t = 4, the radius will have increased to 8 m.
now we will put the values in formula dr/dt
</span>so it will be.dA/dt=2π(8)(2)
=32π
=100.53 is the answer
hope it helps
Answer:
45 i think
Step-by-step explanation:
i could be totally wrong about this but im pretty sure that if an initial price is 100 percentages are really easy. so 100 minus 60 is 40 and with a 5 percent tax thats 45.
