earbuds
we have a 1in : 0.2in scale of drawing to reality.
0.2 = 2/10 = 1/5
so, 1in in the drawing is actually 1/5in in reality.
how long are the 4in in the drawing ?
well, 4 times the 1in thing.
4×1/5 = 4/5 = 0.8in long
again the similar triangles
similar triangles means that each pair of corresponding lines (sides, heights, ...) in the triangles follows the same scaling factor for the length.
so, what do I need to multiply the side of the large triangle with to get the corresponding side length of the small triangle ?
27 × x = 9
x = 9/27 = 1/3
and that is the scale factor.

Answer:
$120
Step-by-step explanation:
r = R/100 = 4%/100 = 0.04 per year,
I = 300 × 0.04 × 10 = 120
I = $ 120.00
The simple interest accumulated
on a principal of $ 300.00
at a rate of 4% per year
for 10 years is $ 120.00.

According to the statement of the question:
<h2>X² = 20</h2>
<em>Let's apply square root to both members</em>
√X² = √20
X = √20
20 = 2² · 5 so √20 = √2² · 5 = 2√5
X = √20 or X = 2√5 or X = 4.4721
