We know that
<span>An electrician can wire a house in ------------> 20 hours
so
100%----------------> 20 hours
X-------------------> 12 hour
x=12*100/20----> x=60%
that means
</span><span>the apprentice in 12 hours complete the (100-60)----> 40%
</span>the apprentice in 12 hours complete -------> 40%
x hours------------------------------------> 100%
x=100*12/40-----> x=30 hours
the answer is
30 hours
Answer:
rule
Step-by-step explanation:
To start, determine how much a non-college graduate would earn over a 40 year period by multiplying their yearly salary by 40, 30,000*40=120,000. Next, increase it by 30%. Do this by taking 30% of 120k to find out how much more money you would make in comparison to a non-college grad, 120,000*.3=36,000. This means a college grad would make $36,000 more than a non-college grad.

Step-by-step explanation:
24 p=72
17. RQ is the same as PS.
PS = -1 + 4x
RQ = 3x + 3
-1 + 4x = 3x + 3
4x = 3x + 4
x = 4
Now plug that into RQ.
3(4) + 3 = RQ
15 = RQ
18. Angles G and E are equal to each other.
G = 5x - 9
E = 3x + 11
5x - 9 = 3x + 11
5x = 3x + 20
2x = 20
x = 10
Plug that x into G.
5(10) - 9
41 = G
19. TE and EV are equal to each other.
TE = 4 + 2x
EV = 4x - 4
4 + 2x = 4x - 4
2x = 4x - 8
-2x = -8
x = 4
Plug that into TE.
4 + 2(4)
12 = TE
20. DB and BF are equal.
DB = 5x - 1
BF = 5 + 3x
5x - 1 = 5 + 3x
5x = 6 + 3x
2x = 6
x = 3
Plug that into DB.
5(3) - 1
14 = DB
