1. 1/9
2. 0
3. -9
4. -1
Reasoning: To get the opposite of a number just add a negative sign or take it away. This can be done to all numbers other than 0
Answer: if the blue rectangles are x, then x = 1/2
1/2 + 1/2 = 1
the green shapes each = 1
so you have 1 + 1 + 1 = 3 which is true so
x = 1/2
Step-by-step explanation:
Answer:
Option A
Step-by-step explanation:
Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF
Area of ΔABH = 
= 
= 9 in²
Area of the trapezoid = 
= 
= 25 in²
Area of ΔDEF = 
= 24 in²
Therefore, area of the given figure = 9 + 25 + 24
= 58 in²
Option A will be the correct option.
Answer:
C = 56.5 cm
Step-by-step explanation:
<h3>
The circumference formula is C = πd. If the diameter, d, is 18 cm, then the circumference of this circle is </h3><h3>
</h3><h3>
C = π(18 cm) ≈ 18π cm ≈ 56.5 cm</h3>
