Answer:
Step-by-step explanation:
If we divide 12.6/4.5 by 3 we receive 4.2/1.5. So yes they are proportional. <span />
The answer should be
12t^2 - 14t
Let me know if it’s right.
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
16 dimes = $1.60
<em>12 quarters</em><em> </em>= $3.00
