Power = Current *Voltage
You already have the current, but not the voltage.
But you are given resistance, and you know that
Voltage=Current*Resistance
Therefore
V=I*R=4*12=48V
So you have 48V
Now you can figure out the Power
P=I*V=4*48=192W
Therefore you have 192W.
hope this helps
Answer:
Step-by-step explanation:
So, Tanvi started with b buttons.
And she gave away 17.
Since she "gave away," this means that we should use subtraction.
Therefore, she now has b-17 buttons.
Our expression is:
Answer:
She would have 24 single shoes. This is because she has 12 pairs and there are 2 of something in each pair. Therefore, Danielle would have 24 single shoes. (12*2=24) Hope this helped!!
Answer:
x=3, y=1
Step-by-step explanation:
2x+y =7
3x-4y =5
Multiply the first equation by 4 so we can eliminate y
4(2x+y =7)
8x +4y =28
Add this to the second equation
8x +4y =28
3x-4y =5
----------------
11x = 33
Divide by 11
11x/11=33/11
x=3
Now we still need to find y
2x+y=7
2(3)+y =7
6+y=7
Subtract 6 from each side
6-6+y=7-6
y= 1
1.introduce a constant k hence
y=kx then find the value of the constant first -4=k2 hence k =-2
y=-2×-6
y=12
Step-by-step explanation:
follow the same procedure for the others and remember if it is inversely proportional then it becomes y=k/x
