Answer:
-11
Step-by-step explanation:
3x+10=2x-1
3x-2x+10=-1
x+10=-1
x=-1-10
x=-11
Circumference = 2

r
r = 12.5
2 *

* 12.5 ~ 78.540
The answer is about 78.540
Answer:
18,000 forks
Step-by-step explanation:
They are making 3,000 forks each hour for 6 hours, so you would multiply 3,000 by 6. 3,000 multiplied by 6 is 18,000.
Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes
