Answer:
<h2>(A) 9</h2>
Step-by-step explanation:
Let’s put the number of the set 6, 10, 2, 7, 13, 15 in order from least to greatest :
2 , 6 , 7 , 10 , 13 , 15
we know that the median is the central value of the number set
then
if the median is 10
then x should be placed between 10 and 13 or 13 and 15
which means
x ≥ 10
therefore
9 could NOT be the value of x
Answer:
Total 25.45 hours will be taken to empty the pool.
Step-by-step explanation:
Time taken by large pumpkin to empty the pool=40 hours
Time taken by the smaller pumpkins to empty the pool=70 hours
Amount of pool emptied by large pumpkin in one hour=
Amount of pool emptied by small pumpkin in one hour=
Amount of pool emptied in one hour if both pumpkins work together=
+ 
=
Therefore, the no. of days will be the reciprocal of the amount of work done in one hour ie . 
Total 25.45 hours will be taken to empty the pool.
9mph because 20 minutes time 3 is one hour so multiply 3 by 3 to get 9
1 radian
because s= r × angle measurement in radian
we have s= arc , r = radian so we got the value
