<em>Hello there, and thank you for asking your question here on brainly.

<u>Short answer: A. 1272 cm</u></em>³
<em>
Why?

When finding the volume of a cone, you use the formula <u>V = </u></em><u><em>πr²h/3. </em></u><em>R = 9, H = 15. V = π9²15/3 9</em>² = <em>81 | 15 / 3 = 5 | 3.14 * 81 = 254.34 | 254.34 * 5 = 1271.2 1272 rounded.

Hope this helped you! ♥</em>

Sanjay and Felipe are putting together a 500-piece puzzle. Sanjay could do the entire puzzle by himself in 6 hours, while it wou
Nata [24]

What is the time it takes Sanjay to complete the puzzle? 6 hours

What is the time it takes Felipe to complete the puzzle? 8 hours


We can use the general formula of rate and time to solve this problem. Generally we have,

<em><u>Rate * Time = Work/Job</u></em>

<em>** where Work/Job for this problem is 1 since they are doing 1 work, which is solving a puzzle</em>


  • <u>Finding rate of Sanjay:</u>

R(6)=1\\R=\frac{1}{6}

  • <u>Finding rate of Felipe:</u>

R(8)=1\\R=\frac{1}{8}


Working together, their rate is the sum,

Total Rate = \frac{1}{6} + \frac{1}{8} = \frac{7}{24}.


Using the general formula again, we can find the time it will take to solve the puzzle when both works together.

(\frac{7}{24})T=1\\ T=\frac{1}{\frac{7}{24}}= \frac{24}{7} = 3.43 hours

Rounding the answer, we have 3.4 hours.


ANSWER: 3.4 hours

Answer:

  all are functions except Relation 2

Step-by-step explanation:

If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.

Only Relation 2 is not a function.
