Answer:
Its 120.
Step-by-step explanation:
40 percent of 300 equals 120.
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
The simplest form is 15/28
Correct me if I'm wrong. Hope this helps!
4.75=4+0.75
0.75=0.75/1=7.5/10=75/100=3/4
4 and 3/4
I think the answer is right triangles sorry its it wrong
