Answer:
x = 10.3
Step-by-step explanation:
x + 24. 5 = 34.8
- 24.5 - 24.5
x = 10.3
Check your answer:
x + 24. 5 = 34.8
10.3 + 24.5 = 34.8
34.8 = 34.8
Hope this helps!
Answer: the answer to lg is 18
Answer:
F = 8.48 x
N
Step-by-step explanation:
The force on an electron in a magnetic field can be determined by;
F = qvB Sin θ
where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.
Thus,
q = -1.6 x
C
v = 106 m/s
B = 0.5 T
θ = 
So that,
F = 1.6 x
x 106 x 0.5
= 8.48 x
N
The force on the electron crossing the uniform magnetic field is 8.48 x
N.
Answer:
50 of D and 10 of C
Step-by-step explanation:
First of all, put this data into 2 equations.
You sold 60 items, so C+D=60
C is $5 so we can represent it by 5C
D is $7 so we can represent it by 7D
You made $400 total from C and D, so 5C+7D=400
We can use simultaneous equations to solve this.
To eliminate one of these variables, we'll multiply the first one by 5 to make it 5C like the other.
5(C+D=60) (make sure you multiply both sides.)
so 5C+5D=300
5C+7D=400
Now we solve it:
5C-5C+7D-5D=400-300
7D-5D=100
2D=100
D=50
Now we can substitute this with one of the equations to find C
C+50=60
C=60-50
C=10
so, (10x5)+(50x7)=400
Select both the 2nd and 4th options!
