Answer:
7.05 in^3
Step-by-step explanation:
V = 4/3(pi)r^3 , r = 3/2 = 1.5
V = (4/3)(3.14)(1.5^3)
= 14.10
Now divide by 2 for 1/2 of the ball.
V/2 = 14.10 = 7.05
= 7.05 in^3
Answer:
(Yes, "5" is a polynomial, one term is allowed, and it can be just a constant!) 3xy-2 is not, because the exponent is "-2" (exponents can only be 0,1,2,...)
Step-by-step explanation:
Answer: 16 g
Step-by-step explanation:
We can solve this with the Radioactive Half Life Formula:
Where:
is the final amount of radioactive calcium
is the initial amount of radioactive calcium
is the time elapsed
is the half life of radioactive calcium
Solving with the given data:
This is the amount of radioactive calcium left
Answer:
5/243
Step-by-step explanation:
4/18 × 6/18 × 5/18 = 5/243
I think
All you have to do is divide
500 divided by 10 equals 50
so 50 cars went on the picnic trip
