Answer:
C)
Step-by-step explanation:
- π can be added to π to get a rational number
π + (-π) = 0
0 is a rational number
It is easier to write the equivalent ratios first, then use that information to find the missing values.
3. ratio: cars/trucks = 3/5, or trucks/cars = 5/3. Missing value: 6/3*5 = 10.
4. ratio: TVs/Computers = 2/7, or Computers/TVs = 7/2. Missing value: 21/7*2 = 6.
4 * 2 = 8
8 + 5 = 13
B, is the correct answer
Answer:
D
Step-by-step explanation:
Using the law of logarithms
• 
x = n ⇔ x = 
given
x = 4 ⇒ x = 
= 81 → D
