Answer:
18/20
Step-by-step explanation:
You just have to multiply by 2
Lets cut this shape into rectangles and triangles.
The rectangles will be 7x3 and 3x4
So that is 21 sq rt and 12 sq ft.
Now the triangles.
One will be 2*3/2 and the other will be 4*3/2
So that is 3 sq ft and 6 sq ft.
In total the hole is 42 sq ft.
Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
=
this is also known as the <em>gradient </em>, meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
=
=
also can be represented into an integer form
answer is <u>1.5</u>
