Answer:
670.21 inches^3
Step-by-step explanation:
To find the volume of the spheres, all you need to know is the formula for the volume of a sphere, which you've included in your problem. From the problem, you also know that r = 2. From here, you calculate the volume of 1 of the spheres, which turns out to be:
V = 33.51032
Since there are 20 spheres in this box, you multiple the volume of a single sphere by 20 to get the total volume occupied by the spheres.
V = 20 * 33.51032
V = 670.2064
If you round to 2 decimal places, this becomes 670.21.
Answer:
0u
7u
6u
2u
Step-by-step explanation:
All of these question are just a matter of adding like terms
For the first one we have
7u+(-u)+(-6u)
which is equal to
7u-u-6u
Which I'm sure you can see is equal to 0 or 0u
10/2u+2u
10/2u=5u
5u+2u=7u
6u+0u
0u=0
6u
6u+(-4u)
6u-4u
2u
Divide 3/5 by 2/3:
3
---
5 3(3)
------ = ---------- = 9/10 (answer). This is not a very satisfactory answer,
2 5(2) because 9/10 is a fraction. 2/3 is
--- larger than 3/5, so the answer would
3 be zero groups.
1) A, 1:2
Because the ratio of the points is 7:14
2) C, 3:5
Because there are 9:15 boys, so divide by 3
3) C, 33 yards
Convert 1200 inches into yards, it makes 33.3
