Answer:
969
Step-by-step explanation:
173 + 212 + 185 + 197 + 202 = 969
82° because
98° + 70° = 168°
360° - 168° = 192°
192° is for two angles, so it can't be 192°, 220°
it's not VERY obtuse angle. So it remains only 82°
(0, 1) (4, -2)
(-2 - 1)/(4 -0) = -3/4
$9.10
455 ÷ 50 = 9.1. The student tickets cost $9.10. (I think)
Find the greatest common factor of both numbers:
Factors for 150:
150: 1, 2, 5 , 6, 10, 15, 25, 30, 50, 75, 150
Factors for 270:
1, 2, 3, 5, 6 , 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
The largest number they both have in common is 30, so the largest tile could be 30 cm^2.
610
Given:
Add:
259 + 431 = 690
Subtract:
1300 - 690 = 610
So, on Wednesday 610 emails were sent out.
Hope this helped.
