Answer:
1/600, 6/100, 1/1400
Step-by-step explanation:
Answer:
7/2
Step-by-step explanation:
Here are the steps to calculating the given equation:
Distribute 2 to x and 6: 2x-12+14=38
Group like terms: 2x+(-12+14)=38
Combine like terms: 2x+2=38
Subtract number on 'x' side: 2x+2-2=38-2
Simplify: 2x=36
Divide: 2x/2=36/2
Simplify: x=18
Label with correct terms:
I cannot do this because you did not provide sufficient information, I would need to know what the difference between the two, or if 'x' stood for one particular temperature. Hope that helped enough with what you provided.
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.
