Answer:1/2
Step-by-step explanation:
Answer:
172 ft
Step-by-step explanation:
Due south and due east form a 90-degree angle.
Her path is a right triangle. The 60 ft and 40 ft distances are the legs of the right triangle. We can use the Pythagorean theorem to find the hypotenuse. Then we add the lengths of the three sides to find the total distance she traveled which is the perimeter of the right triangle.
a^2 + b^2 = c^2
(40 ft)^2 + (60 ft)^2 = c^2
1600 ft^2 + 3600 ft^2 = c^2
c^2 = 5200 ft^2
c = 72 ft
perimeter = a + b + c = 40 ft + 60 ft + 72 ft = 172 ft
Answer:
3rd one
Step-by-step explanation:
It is the most reasonable answer
Answer:
A. The lines stay parallel
Step-by-step explanation:
Rigid transformations do not change angle or line relationships. When the parallel lines are rotated they stay parallel. Reflecting them will keep them parallel. If this were not true, then figured with parallel lines like rectangles and squares would change shape when reflected.
Answer:
No Solutions
Step-by-step explanation:
Multiply the first equation by 5,and multiply the second equation by 2 to get a least common multiple for the x's.
5(4x+6y=3)
2(−10x−15y=−4)
It becomes:
20x+30y=15
−20x−30y=−8
Add these equations to eliminate y:
0=7
Answer:
No solutions.
