Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²
Answer:
0.07
Step-by-step explanation:
0.70-0.63
Answer:
<h2>The radius r = 22.5 cm</h2>
Step-by-step explanation:
The formula of a circumference of a circle:
r - radius
We have the circumference
Substitute:
<em>divide both sides by π</em>
<em>dvide both sides by 2</em>
Y=1/2+4
1/2=Slope (M)
4= Y-intercept (B)
The 35% is 81.90 plus the 234. So your answer would be $315.90 is the original price. If you need me to explain it let me know :)
