Answer:
1) Appliances are connected in parallel
2) Appliances are connected in parallel
3) Appliances are connected in parallel (because in house , appliances are connected in parallel)
4) Advantage :- Such kind of connections assures that even if one or more appliances stops working , the working of other appliances will remain unaffected because in such connections , voltage remains constant
Disadvantage :- Such circuits can draw more power which leads to high bill charges on electricity. Also such connections need more wiring.
Answer:
The lower score is -12, and he wins buy (12 -9) , or 3 points
Answer:
9x, 8x+12
Step-by-step explanation:
x(2x+7)-2x(x-1)
=> 9x
The general equation for computing the circumference of a circle is
![C=\pi d](https://tex.z-dn.net/?f=C%3D%5Cpi%20d)
, where C is the circumference, and d is the diameter. (You might also see the equation as
![C=2 \pi r](https://tex.z-dn.net/?f=C%3D2%20%5Cpi%20r)
where r is the radius, because
![d=2r](https://tex.z-dn.net/?f=d%3D2r)
)
Computing the circumferences of the two circles, we get:
![C_{d=15}=\pi (15)=15\pi](https://tex.z-dn.net/?f=C_%7Bd%3D15%7D%3D%5Cpi%20%2815%29%3D15%5Cpi)
![C_{d=30}=\pi (30)=30\pi](https://tex.z-dn.net/?f=C_%7Bd%3D30%7D%3D%5Cpi%20%2830%29%3D30%5Cpi)
.
To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"
![\frac{C_{d=30}}{C_{d=15}}=\frac{30\pi}{15\pi}=2](https://tex.z-dn.net/?f=%5Cfrac%7BC_%7Bd%3D30%7D%7D%7BC_%7Bd%3D15%7D%7D%3D%5Cfrac%7B30%5Cpi%7D%7B15%5Cpi%7D%3D2)
So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.
