would be your answer. Hope I helped!
Vsphere=(4/3)pi(r)³
remember that d/2=r, so 2r=d
given
V=2400
2400=(4/3)pi(r)³
times both sides by (3/4)
1800=pi(r)³
divide both sides by pi
1800/pi=r³
cube root both sides
<span>8.30566118415=r
times 2
</span><span>16.6113223683=r</span>
the aproximate diameter isi 16.6 cm
Answer:
-x^2+15x+2/x
Step-by-step explanation:
All steps that Marcie did are right, but she forgot to change sign in last step.
Consider the inequality

Then

Group the numbers:

Separate terms with x and without x in different sides:

The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:

Answer: Marcie forgot to change sign in last step.
