Answer:

<u>The original price of the coat was £ 275</u>

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Sale price of the coat = £ 220

Discount from the original price = 20%

2. Let's find the original price of the coat

Original price of the coat = x

Sale price of the coat = £ 220

Sale price of the coat = x - 20%x

220 = x - 0.2x

220 = x - 2x/10 (0.2 = 2/10)

2,200 = 10x -2x (Multiplying by 10 at both sides)

2,200 = 8x

2.200/8 = 8x/8 (Dividing by 8 at both sides)

275 = x

<u>The original price of the coat was £ 275</u>

Answer:

a = 60°/2 = 30°

b = 84/2 = 42°

c = (100+60)/2 = 80°

d = 360-100-60-84 = 116°

a. For each of the Five Platonic Solids, count the number V of vertices, the number F of faces, and the number E of edges. Check

natita [175]

Answer:

1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2

2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2

3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2

4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2

5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.
