Answer:
1/8 room
Step-by-step explanation:
(3/4 roll)/(6 rolls/room) = (3/4)(1/6) rooms = 1/8 rooms
With 3/4 roll of wire, the electrician can wire 1/8 of a room.
Answer:
17:27
Step-by-step explanation:
You would start with 34:54
this reduces to 17:27
Answer:
option C
Step-by-step explanation:
m∠3 =m∠6 ( Alternative Interior Angles are equal )
But m∠5 & m∠6 are linear pair. So ,
m∠5 + m∠6 = 180°
=> m∠5 + m∠3 = 180° ( because m∠3 =m∠6 )
I assume you're asked to solve
4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0
Factor the left side:
(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0
Then either
4 cos(<em>x</em>) - 3 = 0 <u>or</u> cos(<em>x</em>) - 1 = 0
cos(<em>x</em>) = 3/4 <u>or</u> cos(<em>x</em>) = 1
From the first case, we get
<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em> <u>or</u> <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>
and from the second,
<em>x</em> = <em>nπ</em>
where <em>n</em> is any integer.
2m+-m=7
3m-8=7
Then add 8 to both sides of the equation.
simplify.
Divide both sides of the equation with the same term.
simplify.
m=5
