Answer:
= 0.95 = 0.485 --> (hundredth) 0.49
Step-by-step explanation:
a) 1/2 of 12 = 1/4 of 24
b) 1/3 of 90 = 2/3 of 45
1/2 of 16 is 6, so 6 would be 1/4 of what? 6 x 4 = 24. 6 is 1/4 of 24. The other one is the same. 1/3 of 90 is 30, and 30 is 2/3 of 45.
50
The median number is known as the middles number
The first step is to rearrange the set of numbers starting from the lowest
25, 32, 32, 32, 33, 40, 47, 47, 48, 55, 56
Hence the middle number is 50
2) The domain would only include positive integers
y cost for x person
x can't be negative or fraction.
c. 12
PA² = (BC + PB) × PB => tangent-secant theorem
PA = 8
PB = 4
BC = ?
Substitute
8² = (BC + 4) × 4
64 = 4BC + 16
64 - 16 = 4BC + 16 - 16
48 = 4BC
48/4 = 4BC/4
12 = BC
BC = 12
