The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.

n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.
The possible values for n are 9, 10, 11, and 12.
Answer:
VX = 8.8 in
Step-by-step explanation:
By applying Sine rule in the right triangle WXV,
Sin(∠W) = 
= 
Sin(34)° = 
VX = 15.Sin(34)°
= 8.8379
≈ 8.8 in.
Therefore, measure of side VX is 8.8 in.
Answer:
Alvin: 49
Elga: 40
Step-by-step explanation:
- The equation is 89 = x + (x-9).
- Remove the parenthesis and combine the like terms. 89 = 2x - 9
- Add 9 on both sides. 98 = 2x
- Divide by 2 on both sides. x = 49
- 49 is the age of Alvin. (49-9) 40 is the age of Elga.
