Answer:
EF=10
Step-by-step explanation:
If they are corresponding,
AB = 2 x Scale factor of 5 = 10
revenue = $2000
labor cost per worker working 40 hrs = 8 . 40 = 320
for 2 workers = 640
as a % of revenue = ( 640 . 100)/2000 = 32%
Answer:
3/5
Step-by-step explanation:

Answer:
sorry im not sure about this..
Step-by-step explanation:...
Two complementary angles = 90°
X = 18+ 2y
X + y = 90
Plug first equation into second
18 + 2y +y = 90
18 + 3y = 90
18 – 18 +3y = 90 – 18
3 y = 72
3y/3 = 72/3
Y = 24
Plug y into 2nd formula
X + 24 = 90
X + 24 -24 = 90 – 24
X = 66
