Answer:
8/10=0.8
8/400=0.02
So 8/10 is greater
Step-by-step explanation:
Slope is equal =
- coefficient of x / coefficient of y
slope = -6/12 = -1/2
D option is correct
Answer:
c
Step-by-step explanation:
We have two right triangles and three different rectangles.
The formula of an area of a right triangle:

l₁, l₂ - legs
We have l₁ = 20cm and l₂ = 21cm. Substitute:

The formula of an area of a rectangle:

l - length
w - width
We have:
rectangle #1: l = 22cm, w = 29cm

rectangle #2: l = 22cm, w = 21cm

rectangle #3: l = 22cm, w = 20cm

The total Surface Area of the triangular prism:

It would be D. 5/20 because the other 2 you would add then subtract and then you would just put the answer yo get from subtracting it over 20.
