21.4*pi(r^3)/3=1000 ,so use r from it to calculate SA=4*pi*(r^2)
don't ask me to do it completely unless u are unable to do it.
22.yes, 1:6
Step-by-step explanation:
1- -7x+2=2x+2-9x
2- -7x-2x+9x= -2+2 collect the like terms and put them on separate sides (always put x on the left hand side and the others on the right hand side). and always convert + to - and reversed (for example: I put the 2x from the right to the left and changed it to -2x)
3- -9x+9x= -2+2 now work out the sum
4- 0x=0 so x=0

Answer:
B. 470 miles
Step-by-step explanation:
Using numbers rounded to the nearest 10, the remaining distance is ...
1270 -420 -380 = 470 . . . . miles
Answer: The domain would be all real numbers.
Step-by-step explanation:
This is not a piecewise function, so it means that the domain, which means all possible x values, is all real numbers, not imaginary.
