BC/AC = EF/DF
10/20 = 20/DF
DF = 40
AB/BC = DE/EF
AB/10 = 36/20
so AB = 18
answer
AB = 18, DF = 40 (A. fist one is your answer)
You are correct. 4 is the slope and 2 is the y intercept.
Reasoning:
y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept
In your case, m = 4 and b = 2.
Answer:
<h2>The height is 87.5 in</h2>
Step-by-step explanation:
We can solve the height of a square pyramid using the Pythagoras theorem, this is because the slant height the height and the section of the base form a right triangle
the slant height is equivalent to the hypotenuse
the height is equivalent to the opposite
while the base(half) is the adjacent
Given
the base of the pyramid= 
the adjacent is = 
the slant height (hypotenuse)= 
we know that Pythagoras theorem states that "The sum of the squares of the lengths of the legs of a right triangle ('a' and 'b' in the triangle) is equal to the square of the length of the hypotenuse ('c').


substituting we have

Answer:
0.72727272727 or 0.73
Step-by-step explanation:
To get that all you have to do is divide 8 by 11. So 8 divided by 11 equals 0.72727272727 which would round up to 0.73
Answer:
Decrease
Step-by-step explanation:
160/40 = 4 units/hour
138/36 = 3.833 units/hour
3.833 < 4
So it's a decrease
