Answer:
55/72 feet squared
Step-by-step explanation:
The area of a rectangle is Length x Height, or Width x Height.
Here, we have a width of 5/6 feet and a height of 11/12 feet.
We multiple 5/6 and 11/12 to get 55/72 feet squared.
If we discuss this as if it is a triangle then the "rise" is the vertical side and the "run" is the adjacent side.
So the ratio of the rise to the run is 8 / 15 which equals

and we find that is 28.072 Degrees

Answer:
95
Step-by-step explanation:
let x be his mark in the fourth test, then
mean = 
= 83 ( multiply both sides by 4 )
83 + 81 + 73 + x = 332
237 + x = 332 ( subtract 237 from both sides )
x = 95
Answer:
4
Step-by-step explanation:
rise/run = slope
As it goes to the left or adds by one, it goes up by 4
4/1
Answer:
Gradient = -3
• Parallel lines have the same gradient, therefore gradient, m is -3
• At point (0, -4)
y intercept is -4
