Answer:
The length of the side of an equilateral traingle 
inches
Step-by-step explanation:
Given that the area of an equilateral triangle is given by
It can be written as
Square inches (1)
To find the length of the side s os an equilateral triangle
Given that area of an equilateral triangle is 
square inches
It can be written as
square inches
It can be written as
square inches (2)
Now comparing equations (1) and (2) we get
Dividing by 
on both sides we get
Therefore inches
Therefore the length of the side of an equilateral traingle inches
5 over 25 = 1/5
1/5 = 20 %
Hope this helped :)
It is important to note that all the information's required are already given in the question
Probability that a day will be hot = 0.15 + 0.10
= 0.25
Probability that a day will be sunny = 0.15 + 0.30 + 0.10
= 0.55
Adding the above two probabilities, we get = 0.25 + 0.55
= 0.80
Now
Probability that a day will be both hot and sunny = 0.15
So
Probability that a day was hot or sunny = 0.80 - 0.15
= 0.65
I hope the procedure is clear enough for you to understand.
Equation of a line is in the form y = mx+c, where m is the gradient and c is the y-intercept.
First step is to find the gradient.
m = (y2-y1)/(x2-x1)
= ( 5- -8)/(8-4) = 13/4
We have y = (13/4)x + c
Now we replace one of the coordinates to find c. Let’s replace (4,-8)
We have: -8 = (13/4)*4 + c
-8=13+c
c=-8-13= -21
Therefore, equation of line is:
y = (13/4)x - 21
