Answer:
its B because
Step-by-step explanation:
Simplifying
41n(7x) = 8
Remove parenthesis around (7x)
41n * 7x = 8
Reorder the terms for easier multiplication:
41 * 7n * x = 8
Multiply 41 * 7
287n * x = 8
Multiply n * x
287nx = 8
Solving
287nx = 8
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '287x'.
n = 0.02787456446x-1
Simplifying
n = 0.02787456446x-1
Answer:
-3
Step-by-step explanation:
you go down from the dot left most and you count towards the line that the second dot falls on and count over too it
Answer:
6 laptops
Step-by-step explanation:
First, find the amount spent on the textbooks:
30(116)
= 3480
Subtract this from the total amount they have to spend:
6500 - 3480
= 3020
Divide this amount by 439 to find how many laptops they can buy:
3020/439
= 6.8
Round down to 6 since you can only have full laptops:
= 6
So, they can buy 6 laptops
Answer:
B
Step-by-step explanation:
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.
