Answer:
The length of the model is 21 inches
Step-by-step explanation:
we have
The scale factor
That means
1 unit in the model represent 12 units in the actual
1 inch in the model represent 12 inches in the actual
Remember that
so
1 inch in the model represent 1 ft in the actual
The scale factor is
therefore
21 ft in the actual represent 21 inches in the model
Answer:
Yes good job!

The above polygon is a pentagon
The polygon has a rectangle and a triangle
Area of triangle FSCW
= Length × width
= 9 × 2
= 18 square units
area of triangle FNS
= 1/2 × base× height
= 1/2 × 9 × 6
= 27 square units
Therefore the area of the polygon is
= 27 + 18
= 45 square units
Step-by-step explanation:
Let x be the principal amount.
Simple Interest Formula:
where a = final amount
p = principal amount
r = annual interest rate
t = time taken in years.
given a = 3x, p = x, t = 25, substitute a,p and t into formula.
