Answer:
about 8.2 cm
Step-by-step explanation:
The key is to realize that the volume never changes.
The formula for the volume of a sphere is (4/3)*pi*radius^3
22/7 is being substituted in place of pi in this problem
The volume of one of the small spheres is
(4/3)*(22/7)*2^3 is about 33.524 cm^3
64 of those spheres would have a volume of 33.524*64, or about 2145 cm^3
Now, the problem is to find a sphere with a volume of 2145 cm^3
Volume = (4/3)*(22/7)*radius^3
plug in and solve
2145 = 4.1905*r^3
r^3=511.87
r is about equal to 8.2 centimeters
Answer:
0, 1, 2
Step-by-step explanation:
So, since there are three consecutive integers, you have the equations
x, x+1, x+2 where x is the smallest number.
The greatest of the three integers= x+2
Finish setting up your equation;
2(x+x+1)=x+2
Combine like terms;
2(2x+1)=x+2
Distribute;
4x+2=x+2
3x=0
x=0
x+1=1
x+2=2
Hope this helps:) Have a good day!
Answer:
Answer is D
Step-by-step explanation:
(3,-7) and (1,-10) belong toD Variant
Yes the distributive property is used to expand expressions, but it is also used to make it simpler.
For an example
3(x+4) + 3(y-8)
This is the same thing as
3x + 12 + 3y -8
