Answer:
It could be -111 and -173
Step-by-step explanation:
-111 is 62 more than -173 and together they are -284.
4/8 because if 2 already got pulled theres only 8 left four blue four yellow theres a 4 out od 8 chance youll pull them like that again
Answer: 294.4 m²
<u>Step-by-step explanation:</u>
Separate the shaded region into two parts:
- The section containing the central angle of 230° (360° - 130°)
- The triangle with sides 11.1, 11.1 & 20.12 (use Law of Cosines)

Area of shaded region = Area of (1) + Area of (2)
= 247.3 + 47.1
= 294.4
Answer:
Step-by-step explanation:
32+(-10)
32-10
22 is not equal to 0
so its false
