Answer: 9 weeks
Step-by-step explanation:
-0.1³ + 0.6x² + 85 = 70
x ≈ 8.21998224
The answer is 9 weeks because you must round 8.22 up to 9. The reason you round up to 9 is because must include the numbers after the decimal in a week, but you cannot have 0.22 weeks, so 0.22 rounds up to 1.

Answer:
18%
Step-by-step explanation:
Step 1: We make the assumption that 90 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100%=90
Step 4: In the same vein, x%=16.2
Step 5: This gives us a pair of simple equations:
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields
Therefore, 16.2 is 18% of 90
