1. The shortest side is always opposite of the smallest interior angle.
2. The longest side is always opposite of the largest interior angle.
1' = 12"
The scale; 1/4" : 1' → 1/4" : 12" → 1" : 48"
Actual large is 48 times greater than on the architectural drawing. Therefore:
2 1/2" = 2.5"; 3 3/4" = 3.75"
2.5" → 2.5" · 48 = 120" = (120 : 12)' =10'
3.75" → 3.75" · 48 = 180" = (180 : 12)' = 15'
Answer: A. 10ft by 15 ft.
The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:

Where,

Substituting values:

We choose an ordered pair:

Substituting values:

Answer:
y = 8.34x + 30
Answer:
c
Step-by-step explanation:
Answer:
The total area:
12 units²
Step-by-step explanation:
There are three parts on this shape:
1 big right triangle
1 rectangle
1 small right triangle
area = (4*4)/2 = 16/2 = 8units²
area = 2*1 = 2units²
area = (2*2)/2 = 2units²
8+2+2 = 12 units²
