Answer: The refrigerator cost in this month is $4.5 approximately.
Step-by-step explanation:
Since we have given that
Amount of watt of electric power = 320 W
Number of days = 30
Unit cost of electricity = $0.13/Kwh
Hold factor = ![\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D)
Number of hours in a month = 24
So, the refrigerator cost in this month would be
![0.13\times 0.32\times \dfrac{1}{4}\times 30\times 24\\\\=\$7.488](https://tex.z-dn.net/?f=0.13%5Ctimes%200.32%5Ctimes%20%5Cdfrac%7B1%7D%7B4%7D%5Ctimes%2030%5Ctimes%2024%5C%5C%5C%5C%3D%5C%247.488)
Hence, the refrigerator cost in this month is $4.5 approximately.
Answer:
(a) 0.2707
(b) 0.8576
Step-by-step explanation:
I believe it is proposition
Notice that x is part of the two triangles.for the bigger triangle
92+85+x=180
177+x=180
x=3
in the smaller triangle
y+100+x=180
since x=3
y+100+3=180
y=77
