Done.
Answer:
The number is 27
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The quotient of 9 and a number added to 30 is 33
30 + (n / 9) = 33
<u>Step 2: Subtract both sides by 30</u>
30 + (n/9) - 30 = 33 - 30
n/9 = 3
<u>Step 3: Multiply both sides by 9</u>
n/9 * 9 = 3 * 9
<em>n = 27</em>

Molly would have to hike for 11 days for it to equal 11/6
<u>Statement</u><u>:</u>
A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s².
<u>To </u><u>find </u><u>out:</u>
The person's final velocity after 3 s.
<u>Solution</u><u>:</u>
- Initial velocity (u) = 3.7 m/s
- Acceleration (a) = 2 m/s²
- Time taken (t) = 3 s
- We know, the equation of motion,
- v = u + at
- Putting the values in the above equation, we get,
- v = 3.7 m/s + 2 m/s² × 3 s
- or, v = 3.7 m/s + 6 m/s
- or, v = 9.7 m/s
<u>Answer</u><u>:</u>
The final velocity is 9.7 m/s in the direction of the motion.
