For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3
There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.
There should be 6 orange picks.
You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.
Answer:
7. ∠CBD = 100°
8. ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°
Step-by-step explanation:
7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.
Then the congruent base angles of isosceles triangle ABC will be ...
∠B = ∠C = (180° -20°)/2 = 80°
The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...
∠CBD = 180° -80°
∠CBD = 100°
__
8. In the isosceles trapezoid, base angles are congruent, and angles on the same end are supplementary:
∠CBD = ∠BCE = 100°
∠CED = ∠BDE = 80°
A quotient is a answer or the sum
answer c. none of the above
