Answer:
Two sides have a measure of 48 cm and the shortest side is 16 cm.
Step-by-step explanation:
this is an isosceles triangle
let x = length of shortest side
let 3x = length of other two sides
find x:
3x + 3x + x = 112
7x = 112
x = 16
3x = 48
The answer is 13. You substitute the x in 2x+5 with 4, because x=4 here. That would give you 2(4)+5. 2(4) is 8, 8+5 is 13. Hope this helped!

Answer: 0.1122
Step-by-step explanation:
Let A denotes the event that it snows in Greenland.
Then A' denotes the event that it does not snow in Greenland.
Let G be the event that glaciers grows.
Given : Suppose that it snows in Greenland an average of once every 27 days.
i.e.
Then,
Also, P(G|A)=0.23 and P(G|A')=0.07
By Bayes theorem , we have
Hence, the probability that it is snowing in Greenland when glaciers are growing= 0.1122
