The <u><em>correct answer</em></u> is:
(8, 20).
Explanation:
We can substitute the values for x in the equation and see if they equal y:
y=16+0.5(0) = 16+0 = 16 ≠ 18. This is not the correct option.
y=16+0.5(5) = 16+2.5 = 18.5 ≠ 19.5. This is not the correct option.
y=16+0.5(8) = 16+4 = 20. This is the correct option.
Solution:
Consider the Given Isosceles Triangle
Considering the Possibilities
Case 1. When two equal angles are of 70°
Let the third angle be x.
Keeping in mind , that sum of Interior angles of Triangle is 180°.
70° + 70° + x= 180°
140° +x= 180°
x= 180°- 140°
x= 40°
Case 2:
When an angle measures 70°, and two equal angles measure x°.
Keeping the same property of triangle in mind, that is sum of interior angles of triangle is 180°.
70° + x° + x° = 180°
⇒ 70° + 2 x° = 180°
⇒ 2 x° = 180° - 70°
⇒ 2 x° = 110°
Dividing both sides by 2, we get
x= 55°
Answer:
310
Step-by-step explanation:
The maximum possible number is obtained when each family owns one appliance only. That total is ...
60 + 85 +70 +95 = 310
The maximum possible number of families is 310.
