19. Find the current in a circuit if the power is 500 W (watts) and the resistance is 25 ohms. Round off your answer to two deci
HACTEHA [7]

Answer:

A

Step-by-step explanation:

The formula that relates current, power and resistance is

I=\sqrt{\frac{P}{R}}

Where

I is the current (in amperes)

P is the power (in watts)

R is the resistance (in ohms)

We know P = 500 and R = 25, we plug them into the formula and solve for I:

I=\sqrt{\frac{P}{R}}\\I=\sqrt{\frac{500}{25}}\\I=\sqrt{20}\\ I=4.47

Correct answer is 4.47 Amperes, or choice A.

2. An electronics store sold 1,500 CD's this year. The previous year, the store sold 990
Vera_Pavlovna [14]

Answer:

52%

Step-by-step explanation:

First, find the difference between this year's sales and the previous'. 1500-990=510.

Now we can divide 990 by 510 to find the percent increase. 510/990=0.515151515152, or 52%.

X+7y=24 and x-9y=-24 doing elimination
nirvana33 [79]
The easy thing to do is eliminate x by subtraction 
 
   x + 7y = 24
- x - 9y = -24
-------------------
      16y = 48

now solve for y and then substitute the value into either original equation to find x

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!
maxonik [38]

The number in parenthesis after f is the x coordinate. Basically, it says which y coordinate is tied with an x value. In choice a, it says that when x is 0 y is 3, etc.

So, you can look at the graph to see which answer choice has a point from the graph. Choice a says (0,3), and that does not match. Choice b says (5,-1) and that does match. So the answer is B.

*(x,y)*
