Answer:
A) rational number
Step-by-step explanation:
56 is a rational number because it can be expressed as the quotient of two integers like 56 ÷ 1.
The similarity relationship is AC / EC = AB / ED.
The length of AB is 157.50m.
<h3>What is the length of AB?</h3>
When two triangles are similar, the ratio of the known sides of the triangles can be used to determine the length of the side of the unknown length.
The similarity relationship is : AC / EC = AB / ED
AC = 160 + 50 = 210
210 / 160 = AB / 120
AB = (210 X 120) / 160 = 157.50

Answer: 16
Step-by-step explanation:
9,10,12,x ,20, 25 so we know the median is 14 which is the middle number.
Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.
we know one of the middle numbers is 12 and we trying to find x .
So we could use the equation x + 12 = 2(14)
x + 12 = 28
-12 -12
x= 16 so X is 16. check: 16+12=28/2 is 14.
256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
