Answer:
Sorry but this is not really a question so we can't answer it
Try to visualize the situation; "A percent multiplied by $45 will be me $27"
$45(x/100)=$27
x/100=27/45
x/100=0.6
x=60%
Therefore, the discount was 60%
Hope I helped :)
Answer:
ax2 + bx + c = 0.
Step-by-step explanation:
<h2>Answer:</h2>
[1] Area of base = 13 × 13 = 169in².
Area of faces = 4 (1/2 × 13 × 8) = 208in².
Surface area = (169 + 208)in² = 377in².
[2] Area of base = 1/2 × 5.2 × 4.5 = 11.7in².
Area of faces = 3 (√3/4 × 5.2²) = 35.1in².
Surface area = (35.1 + 11.7)in² = 46.8in².
[3] Area of base = 7 × 10 = 70in².
Area of faces = 2(1/2 × 7 × 6) + 2(1/2 × 10 × 4.8)
= 98in².
Surface area = (70 + 98)in² = 168in².
