Answer:
1/16 or 0.0625
Step-by-step explanation:
we can take 4 outside the parentheses and we would get 4^(4-7+1)=4^(-2)= 1/(4^2)=1/16=0.0625.
Answer:
≈ 38.14 cm²
Step-by-step explanation:
Diameter of circle= 6.97 cm
Area of circle = ?
- Area = πr² = πd²/4 =
- 3.14*(6.97)²/4 ≈ 38.14 cm²
60-3d + 20-6 =4d
74-3d =4d
-3d =4d -74
-7d = -74
D=74/7
Actually I didn't see the (-5, -27), the answer would be -2.
