Answer:
B. A triangle can have only 1 right angle.
Step-by-step explanation:
Think of a right angle as an L. If you have an L connecting to a backwards L, you have an open shape. Triangles have 3 sides and are closed shapes. If a triangle has two right angles, you could connect the two ends but that would give you a square or triangle.
Hope this helped!
Answer:
8
Step-by-step explanation:
Total length of the fabric is ![6\dfrac{2}{3}=\dfrac{20}{3}\ \text{yards}](https://tex.z-dn.net/?f=6%5Cdfrac%7B2%7D%7B3%7D%3D%5Cdfrac%7B20%7D%7B3%7D%5C%20%5Ctext%7Byards%7D)
We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.
Let she needs x scarves. So, ATQ
![x\times \dfrac{5}{6}=\dfrac{20}{3}\\\\x=\dfrac{20}{3}\cdot\dfrac{6}{5}\\\\x=8](https://tex.z-dn.net/?f=x%5Ctimes%20%5Cdfrac%7B5%7D%7B6%7D%3D%5Cdfrac%7B20%7D%7B3%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B20%7D%7B3%7D%5Ccdot%5Cdfrac%7B6%7D%7B5%7D%5C%5C%5C%5Cx%3D8)
Hence, she can make 8 scarves.
Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
