Answer:
Y = 12
Step-by-step explanation:
3/9 = 4/y
By cross multiplying, we get
3*y = 4*9
3y = 36
Y = 12
This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!
The answer is 4/15, because we have to get the denominaters to be the same, so the LCM of 5 and 15 is 15, so 15/5 is 3 and 4*3 is 12. Now, its 12/15-8/15 which is 4/15. Hope this helps!
Answer: Average or Mean
Step-by-step explanation:
The center of measure calculated was the average or mean. To get the mean of a set of numbers, we have to add all the numbers given and then divide them by the numbers.
In this case, the mean of 3,7,11,11,16 will be:
= (3 + 7 + 11 + 11 + 16) / 5
= 48/5
= 9.6
