Answer:
x - y = 5
x + y = 23
x = 14, y = 9
Step-by-step explanation:
Make x subject:
x = 5 + y
Substitute c by (5 + y) :
( 5 + y) + y = 23
2y = 18
y = 9
Substitute y (9):
x = 5 + 9
x = 14
Answer:6.0002inch
Step-by-step explanation:
Volume of sphere=904.39
π=3.14
Volume of sphere=4/3 xπ x r^3
904.39=4/3 x 3.14 x r^3
904.39=(4x3.14xr^3) ➗ 3
904.39=(12.56xr^3) ➗ 3
Cross multiplying we get
904.39x3=12.56xr^3
2713.17=12.56xr^3
r^3=2713.17 ➗ 12.56
r^3=216.02
Taking the cube root of both sides
r=3√216.02
r=6.0002
