Answer:
3.315
Step-by-step explanation:
This would simply be y=8x. Which is not one of the options. Are you sure that is the function?
6. The lengths of two tangent lines to a circle are equal, which can be proved using similar triangles. The perimeter is 2*(3+2+5)=10.
14. c=40 degrees, since c and the given 40 angle correspond to the same arc on the circle. b=40, since b and the given angle are alternate interior angles of two parallel lines. d=180-40-40=100 degrees. a=180-d=180-100=80 degrees.
18. a is two times the given angle according to the inscribed angle theorem. a=2*20=40. b=180-a=140. c=90 since the tangent line is perpendicular to the diameter of the circle.
19. b=85, a=95. Connect the two points on the circle near 45 degrees on the diagram. b is the sum of the two angles formed (b is the exterior angle of the small triangle), and the sum is half the central angles they correspond to, which is 360-145-45=170. So b=170/2=85, and a=180-85=95 degrees.
20. Use power of a triangle. 5*(10+5)=6(6+x), x=6.5.
3 ft is equal to 36 inches, so they are the same length
Answer:
3. 2.5
4. $5 per candy bar
5. You mowed 6 lawns
6. 15.66 is the number
7. 13 weeks
8. 135 students came
9. 12
Step-by-step explanation:
3. 25+7= 32.
81/32= 2.5
4. 23-3= 20
20/4= 5
5. 155-35=120
120/20=6
6. 10-4 = 6
94/6=15.66
(not 100% sure about this one)
7. 200-161=39
39/3=13
8. 975-300=675
675/5=135
9. 36-12=24
36/3= 12
(not 100% sure about this one)
Bonus: Sorry I don't know
I hope I can help! Also next time do each question one by one so other people can answer and not answer all of them if they don't know one.
