Answer:
<u>Triangle ABC and triangle MNO</u> are congruent. A <u>Rotation</u> is a single rigid transformation that maps the two congruent triangles.
Step-by-step explanation:
ΔABC has vertices at A(12, 8), B(4,8), and C(4, 14).
- length of AB = √[(12-4)² + (8-8)²] = 8
- length of AC = √[(12-4)² + (8-14)²] = 10
- length of CB = √[(4-4)² + (8-14)²] = 6
ΔMNO has vertices at M(4, 16), N(4,8), and O(-2,8).
- length of MN = √[(4-4)² + (16-8)²] = 8
- length of MO = √[(4+2)² + (16-8)²] = 10
- length of NO = √[(4+2)² + (8-8)²] = 6
Therefore:
- AB ≅ MN
- AC ≅ MO
- CB ≅ NO
and ΔABC ≅ ΔMNO by SSS postulate.
In the picture attached, both triangles are shown. It can be seen that counterclockwise rotation of ΔABC around vertex B would map ΔABC into the ΔMNO.
Answer:
<u>10 sundaes</u> will be vanilla.
Step-by-step explanation:
Given:
Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.
1/3 of the Sunday's are mint ice-cream.
And 1/2 of the remaining sundaes are chocolate.
The rest are vanilla.
Now, to find the number of sundaes that will be vanilla.
Fernando is making sundaes total = 30.
So, the quantity of sundaes that are mint ice-cream:
<em>Thus, 10 sundaes are mint ice-cream.</em>
So, the remaining sundaes are:
<em>Thus, the remaining sundaes are = 20.</em>
Now, to get the quantity of chocolate sundaes of the remaining sundaes:
<em>Hence, 10 sundaes are chocolate of the remaining 20 sundaes.</em>
<em>As, given the rest are vanilla.</em>
Now, to get the vanilla sundaes we subtract the 10 chocolate ice-cream from the 20 remaining sundaes:
Therefore, 10 sundaes will be vanilla.
