60 + 0.50(x - 40) < = 270
60 + 0.50x - 20 < = 270
40 + 0.50x < = 270
0.50x < = 270 - 40
0.50x < = 230
x < = 230/0.50
x < = 460 miles <==
They’re both the same equation but the first one is simplified
Answer:
8.25475 m
Step-by-step explanation:
pi*r^3 is the formula for a sphere.
Using this, pi is a nmber (about 3.14) and we only don't know the radius, but we know what it equals.
pi*r^3=1,767.1
First divide by pi, then get ride of the cube by cube rooting both sides.
The cube root of 1767.1/pi (remember to cube root both denominator and numberator!!!) is about 8.25475 m
