Answer:
19 and 20
Step-by-step explanation:
19^3 = 6859
20^3 = 8000
7201 is between the two numbers.
S would be equal to 10. We’d multiply 45 by 2 to get the 90 then divide by 9 to isolate it
So, 350 out of 1750
350/1750=
.1828/1
percent is parts out of 100 so x%=x/100
make bottom number 100
0.1828/1 times 100/100 =18.28/100=18.28%
