(1/7)*42=6
(2/3)*42=28
6+28=34
42-34=8
8/42=4/21
your answer is 4/21
<h2>Greetings!</h2><h3>First when doing an inequality, if you find it easier to think of the ≤ signs as equal signs it can make it look easier. </h3>
14 = 2t + 18 = 20
<h3>Because we need to isolate the t, we need to subtract 18 from either side:</h3>
14 - 18 ≤ 2t + 18 - 18 < 20 - 18
<h3>Which then simplifies to:</h3>
-4 ≤ 2t < 2
<h3>Now, to get the t without two lots of it, we simply divide all sides by two:</h3>
-2 ≤ t < 1
<h3>So this means that t is smaller than one and bigger than or equal to -2, and the graph that shows that is C, because it includes -2 but is less than 1.</h3>

Answer:
20
Step-by-step explanation:
First, rewrite the numbers in numerical order:
8, 10, 10, 15, 15, 20, 20, 20, 20, 25, 25, 25, 35
Then find the middle number: (note there's 6 numbers on each side of <u>20</u>)
<em>8 10 10 15 15 20 </em><u>20</u> <em>20 20 25 25 25 35</em>
Hope this helps!
Answer:
C.
Step-by-step explanation:
......................
Surface area of the cylinder = 2 pi r * 40 = 2 pi * 3* 40 = 24 pi
of the cone this is pi * 3 * 5 = 15pi
of the hemisphere this is 1/2 * 4 * pi * 3^2 = 18pi
So the answer is 24pi + 15pi + 18pi = 57pi = 178.98 cm^2
