TheThe smallest diameter of wrapper that will fit the candy bar is 5cm.
<h3>Smallest diameter</h3>
Given:
AD = DC
AC = AD + DC
Segment AD = 2.5cm
Hence:
AC = AD + AD (AD = DC)
AC = 2AD
Where:
AD=2.5
So,
AC = 2(2.5cm)
AC = 5cm
Therefore the smallest diameter of wrapper that will fit the candy bar is 5cm.

255 hours / 85 hours = 3.
This means that the bacteria will double in size 3 times.
900,000 × 2 = 1,800,000
1,800,000 × 2 = 3,600,000
3,600,000 × 2 = 7,200,000
After 255 hours, the colony of bacteria will be 7,200,000
Answer:
9a + 6b and 5c - 3d
Step-by-step explanation:
(a)
4a + 7b + 5a - b ← collect like terms
= (4a + 5a) + (7b - b)
= 9a + 6b
(b)
6c + 4d - c - 7d ← collect like terms
= (6c - c) + (4d - 7d)
= 5c - 3d
20x + 15y = 2000
x + y = 115
55+60=115
20 (55) + 15 (60)=2000
1100+900=2000
2000=2000
