Answer:
<em>The single percentage change is 27.46%</em>
Step-by-step explanation:
<u>Percentage</u>
Suppose x is the initial number. It will be decreased by 7%.
(7/100)x=0.07x
x - 0.07x = 0.93x
This last number will be decreased by 22%.
0.93x*(22/100)=0.2046x
0.93x-0.2046x=0.7254x
The last number is 72.54% of the initial number. This is equivalent to a single decrease of:
100% - 72.54% = 27.46%
The single percentage change is 27.46%

sorry bout the others. idk how to word it so hopefully what I gave you helps
Answer:Parts of two triangles can be proportional; if two triangles are known to be similar then the perimeters are proportional to the measures of corresponding sides. Continuing, if two triangles are known to be similar then the measures of the corresponding altitudes are proportional to the corresponding sides.
